GETTING STARTED

Initialization

Intializing the Receiver

The first time you power up your new GPSMAP 185 Sounder is an important step

in getting the best possible GPS performance. The receiver must be given an oppor-

tunity to collect satellite data and establish its present position. To ensure proper ini-

tialization, the GPSMAP 185 Sounder is shipped from the factory in AutoLocate

mode, which will allow the receiver to find itself anywhere in the world. To speed

up the initialization process, we recommend using the graphic initialization process

described below, which will usually provide a position fix in about a minute.

Before you initialize, make sure the GPSMAP 185 Sounder unit and antenna have

been correctly installed on your vessel according to the instructions in Appendix A.

To turn the GPSMAP 185 Sounder on:

1. Press and hold the

key until the power tone sounds.

The welcome page will appear while the unit conducts a self test. Once the

internal test is complete, the mariners warning will appear, asking you to read and

acknowledge important information regarding the proper use of electronic charts.

To acknowledge the mariners warning:

1. Press the

key.

A message alert and prompt will also appear to ask you to select an initialization

method.

To view a system message:

1. Press the

key.

2. Press the

key again to return to the previous page.

A. The welcome page will be displayed while

the unit performs a self-test.

B. Confirm the Mariners Warning before

starting navigation. Remember that the

electronic chart is designed as a supple-

ment to local government charts, not as a

replacement.

A B

The select initialization window will appear, with the select from map option

highlighted.

1. Press

to initialize the receiver from the built-in worldwide map.

The map page will appear, prompting you to select your approximate present posi-

tion with the map cursor.

1. Use the

keypad to move the map cursor to a location close to your present position. If you

have difficulty identifying your exact position, press the

key to zoom in to a lower map

scale.

2. Press

to confirm your selection.

The GPSMAP 185 Sounder will now begin searching for the appropriate satellites

for your present position and should acquire a fix within a minute or so. While the

receiver searches for satellites, a flashing satellite icon will appear at the left-hand side

of the status bar located at the bottom of the screen. The status bar is used to monitor

the current status of functions such as satellite signal reception, activated alarms, and

also constantly shows the digital depth. A signal strength bar for each satellite in view

will appear on the lower half of the page, with the appropriate satellite number under

each bar. The progress of satellite acquisition is shown in three stages:

 No signal strength bars the receiver is looking for the satellites indicated.

 Hollow signal strength bars the receiver has found the indicated satellite(s) and is col-

lecting data.

 Solid signal strength bars the receiver has collected the necessary data and the satel-

lite(s) is ready for use.

Once the receiver has collected information from at least three satellites, the flash-

ing satellite icon on the status bar will glow steadily, and the GPSMAP 185 Sounder is

ready for use.

GETTING STARTED

Initialization

A. Use the arrow keypad to move the cursor to a

location close to your present position.

B. Hollow signal strength bars will appear on the

status page while the receiver collects satellite

GPSMAP 185 Sounder Getting Started Tour

The GARMIN GPSMAP 185 Sounder is a powerful electronic navigation and

depth sounding system that provides detailed chart coverage and convenient con-

trol of many advanced features right from the screen display. This tour is designed

to take you through the basic pages and functions of the system using the simula-

tor mode. Once youre familiar with the main pages and functions of the unit, refer

to the reference section for instructions on performing specific tasks and functions.

The Getting Started tour assumes that the receiver has been properly installed

and initialized, and you have not changed any of the default unit settings. If you

have changed any settings (position formats, units of measure, etc.), the descrip-

tions and pictures in the tour may not match your configuration.

To turn the GPSMAP 185 Sounder on:

1. Press and hold the

key until the power tone sounds. The welcome page will appear

while the unit conducts a self test.

2. Once the self test is complete, press the

key to acknowledge the mariners warning.

The satellite status page will appear as the receiver begins acquiring satellites.

From the status page, you may also adjust the screen contrast and backlighting.

To adjust the screen contrast:

1. To increase the screen contrast, press the right arrow of the

keypad.

2. To decrease the screen contrast, press the left arrow of the

keypad.

B. The status bar at the bottom of the screen is

displayed at all times. It continuously shows

current depth and displays icons which show

what mode the unit is in, satellite signal pres-

ence, and which alarms (if any) have been trig-

gered. The current scale will also be displayed if

you are viewing the navigation or map page, or

if you are using the sounder zoom function.

A B

The GPSMAP 185 Sounders status page provides a visual reference of satellite

acquisition and receiver status, with a signal strength bar graph and a satellite sky

view in the center of the page. Each page of the GPSMAP 185 Sounders system

also features an options page, which gives you access to other functions and fea-

tures that relate to the specific page you are viewing. To get a feel for how the

options pages work, lets put the GPSMAP 185 Sounder into simulator mode.

To place the GPSMAP 185 Sounder in simulator mode:

1. From the status page, press the

key. The options page will appear, displaying a menu

of options and functions for the status page.

2. Use the UP or DOWN arrow of the

Once the simulator has been started, the status field at the top of the page will

display a Simulating Navigation status. Now youre ready to continue the rest of

the tour. Keep in mind that the GPSMAP 185 Sounder does not track satellites in

simulator mode, and this mode should never be used for actual navigation or to

determine the water depth. All the waypoint and route planning done in simula-

tor mode will still be retained in memory for future use.

GETTING STARTED

Status Page/Simulator Mode

A. To start the simulator, confirm the simulator

warning. Simulator mode should never be

used for actual navigation.

B. Whenever the GPSMAP 185 Sounder is in

simulator mode, a Setup Simulator? option

Page Sequence/Position Page

The satellite status page is one of five main pages used in the GPSMAP 185

Sounders system. All five pages are linked together in a simple chain, which

allows you to scroll through the pages in either direction using the

and

keys. To continue the tour, lets move on to the next page, the position page.

To scroll to the next page in sequence:

1. Press the

key.

The GPSMAP 185 Sounders position page shows where you are, what direction

youre heading and how fast youre going. The compass tape at the top of the page

indicates the direction youre moving. The four user-selectable data fields below

the compass tape show your current course and speed over ground, along with a

resettable trip odometer and depth display. Your current latitude and longitude,

along with a 12/24-hour clock, appear at the bottom of the page.

Now that youve seen how the status and position pages can be used to monitor

satellite acquisition and your present position, lets take a minute to learn how to

mark and store our present position as a waypoint. (Since were in simulator

mode, the present position displayed will be the last position calculated by the

receiver, which should be the spot where youve initialized the unit.) This will also

give you an opportunity to see how the GPSMAP 185 Sounders keypad and

key are used for data entry.

described in the reference section of the manual and/or on your GPSMAP 185

Sounder quick reference guide. To continue our tour, lets move on to the

sounder page.

GETTING STARTED

Marking A Position

ss The mark position page will automatically

assign a default three-digit name for each

waypoint, which can be changed at any time

to an alphanumeric name containing up to

tion.

1. Press the

key.

The sounder page lets you use the GPSMAP 185 as a fishfinder. The top of the screen

contains any of thirteen selectable data field options, while the middle of the page contains a

right-to-left moving sonar image of the water beneath your boat. (Note: Items appear on the

screen as they pass under your transducer. Those objects appearing on the right side of the

screen are closer to you than those on the left.) Fish are displayed as a darkened arch or a

fish icon in three different sizes. Thermoclines (layers of water separating warmer water

above from cooler water below) are shown as shades of gray.

The area of strongest sonar return (or whiteline) is displayed as a solid gray. Typically, the

bottom will be the primary source of the whiteline. A thin whiteline indicates a softer bot-

tom while a thick whiteline shows a harder bottom. A black line is used to show the point

where water meets the whiteline. This black line will follow the bottom contour, along with

any significant objects lying on the bottom. Along the right side of the screen is an adjustable

scale which reflects the depth of the area being displayed. The status bar at the bottom of the

page displays satellite signal status, digital depth, and any triggered alarms. More on the

we take off on our practice route, lets take a brief look at its various features and

displays.

The map display, located in the middle of the page, shows your boat as a triangle

marker on an electronically generated chart. Geographic names, markers and buoys

that are provided by the Micro G-chart cartridge youre currently using are also

shown. It also displays your track, routes and nearby waypoints. An on-screen

cursor lets you pan to other map areas, determine the range and bearing to a posi-

tion, and perform various waypoint and route functions.

The data window, located at the top of the page, provides a user-selectable dis-

play of various navigation data, including course, speed over ground, and bearing

and distance to the cursor or a particular waypoint. The status bar, located at the

bottom of the page, displays the current map scale setting, as well as the status

information described on page 21.

The split screen functions as a map page only

and any changes to the sounder display must be

made from the sounder page. Use the QUIT or

PAGE key to quickly switch between the map

split-screen and the sounder page.

B. The map page can also be configured to display

additional data fields and a graphic course devi-

ation scale or compass. See page 40 for more on

map options.

Using the Map Cursor

Working from the map page is a simple process that centers around the use of

the cursor. Controlled by the

keypad, the cursor is an important tool that can

be used to pan to other map locations, mark and edit waypoints and routes, and

review position data of on-screen navaids and waypoints.

To get a feel for using the map page and using the cursor, try the following

exercise:

1. Use the

key to set the map scale to the 64 nm setting. Your boat should be near the

center of the map, at the receivers last known position. (If your boat isnt where it

should be, make sure that you have initialized the receiver and acquired a position as

described on pages 1-2.)

2. Use the DOWN arrow of the

keypad to move the cursor down to the first lat/lon grid

south of your boats position.

3. Using the

keypad to move the cursor, try following the outline of the lat/lon grid clos-

est to your boat. Notice how another data field appears at the top of the page, showing

the bearing and distance from your boat to the cursor, along with the lat/lon of the cur-

sor.

4. Press the

key to remove the cursor and recenter your boat on the map display.

As you become more familiar with the cursor, youll see that the map display

actively scrolls or pans, letting you explore areas around the world (even outside

of your current Micro G-chart coverage) and create waypoints and routes.

Wherever you move the cursor, youll always be just one

keystroke away

from returning the map to your present position.

Now that you have a feel for how the cursor works, lets move on and see how

the GPSMAP 185 Sounder works on the water. To help you practice using the

map page and other features, weve stored a practice route in the receivers perma-

nent memory so you can see exactly what youll experience when youre navigat-

ing with your new GPS chartplotter.

GETTING STARTED

Map Cursor

A. Whenever the cursor is active, the bearing

and distance of the cursor from your present

position will appear in a pop-up data win-

dow. To remove the cursor and recenter your

vessel on the map, press the QUIT key.

B. To select an on-screen waypoint, simply

move the cursor over the desired waypoint.

The waypoint/navaid name and position,

along with the bearing and distance from

your present position, will be displayed.

Note: Underwater waypoints are also shown

on the map. 11

Going to a Destination

GPS is all about marking positions as waypoints and navigating to them using

the receivers steering guidance and map displays. Weve already seen how to use

the

key to store our present position, so its time to move on to the fun

partgoing to a destination. The

key, located on the left side of the keypad

above the

key, is the primary tool used to select a destination waypoint or a

route to navigate. The

key can be used in three primary ways:

 Pressing

once displays a list of all waypoints in memory, from which

you can select a single destination waypoint.

 Pressing

followed by the

key provides a list of GOTO options

that lets you start a TracBack

route, select a destination waypoint from

the nearest waypoints list, select a stored route to navigate, or cancel the

current GOTO destination.

 Pressing

twice allows you to graphically select an on-screen waypoint,

navaid or cursor position as a destination directly from the map display.

For our simulated trip, were going to select the pre-programmed tour route

[the second method], which will automatically place our vessel at the first route

waypoint. This will also give us an idea of how the

key is used throughout

the GPSMAP 185 Sounder system to provide context-sensitive options and func-

tions. Lets give it a try by activating the practice route stored in memory for navi-

gation:

1. Press

. The waypoint list page will appear. (If we were selecting a single waypoint

to navigate to rather than a route, we would highlight the waypoint and press

2. Press

to display the context-sensitive options available for the GOTO function.

3. Use the

keypad to highlight the Select Route? option. Press

to confirm.

4. The select route page will appear, with the GPSMAP TOUR route highlighted.

5. Press

. The map page will reappear and display five waypoints chained together in

a simple route, with your boat at the first route waypoint.

GETTING STARTED

Using the GOTO Function

A. Pressing GOTO once displays a list of all way-

points stored in memory. To pick a destination,

select the desired waypoint and press

EDIT/ENTER.

B. The GOTO options page allows you to either

start a TracBack route back home, select a des-

tination from the nearest waypoints list, or

select a route to navigate.

A B

A data field at the top of the page will now display the bearing and distance to

the second route waypoint. To get started, lets enter a speed for our vessel, which

we can do from the Setup Simulator? listing on the options page. The setup sim-

ulator page is also available from any other page in the main page sequence.

To enter a boat speed:

1. Press the

key to display the map options page.

2. Use the

keypad to select the Setup Simulator? option and press

3. Once the setup simulator page appears, press

to access the SOG field.

4. Use the

keypad to enter a speed of 60 knots.

5. Press

to finish, and

to return to the map display.

Once a speed has been entered, youll notice that the map will begin to move

slowly, keeping your boat centered on the display. To get a better view of whats

going on, zoom in to a closer map scale.

1. Press the Ckey to select the 16 nm scale.

Youll now have a clearer picture of the route we are navigating, along with an

outline-only presentation of the surrounding shoreline. Because the usable range

of the built-in database is only valid to 64 nm scale, we no longer have full cartog-

raphy available. Keep in mind that whenever you do exceed the usable range of

the built-in database or the Micro G-chart cartridge in use, the range field will dis-

play OVR ZM or NO MAP to indicate that you should exercise extreme caution

using the cartography data. See pages 39 and 81 for more information on map

scales and using Micro G-chart detailed cartography.

Now that weve zoomed in a little closer to our route, we can pan ahead of our

vessel with the cursor to review and create on-screen waypoints and navaids. Try

moving the cursor to select the TOUR3 waypoint just use the

keypad to

move the cursor as close as possible to the waypoint. (To move the cursor in small

increments, try a series of short key presses.)

GETTING STARTED

Simulator Setup/Map Scales

A. To enter a boat speed or define the simulated

course, highlight the Setup Simulator? option

and press EDIT/ENTER.

B. Enter a boat speed of 60 knots to begin the

tour. This will allow you to complete the

Getting Started tour in 10-15 minutes.

Once the cursor is over the TOUR3 waypoint, youll notice that the waypoint

symbol and name will become highlighted. The data field at the top of the page

will display the waypoint name, the range and bearing from your present position,

and the coordinates for the waypoint.

To review the waypoint page for a selected waypoint:

1. Press the

key.

2. To return to the map page, press

again.

The cursor can also be used to create new waypoints right from the map

display.

To create a new waypoint using the cursor:

1. Use the

keypad to move the cursor as close as possible to the following position:

N 35º 02.129; W 076º 26.106 (Use the data window to verify the cursor position.)

2. Press the

key to capture the cursor position.

3. Use the

key to highlight the waypoint symbol field.

4. Press

to access the symbol page.

5. Press the DOWN arrow of the

keypad twice to select the wreck symbol.

6. Press

to confirm, and

again to finish.

GETTING STARTED

Navigation Page

Now that were navigating to an actual destination, lets move on to the next

page of the GPSMAP 185 Sounder system, the navigation page:

1. Press the

key.

The navigation page provides graphic steering guidance to your destination.

The bearing (BRG) and distance (DIS) to the destination, with your current course

(COG) and speed over ground (SOG), are displayed at the top of the page, along

with a compass tape to indicate your cardinal heading. The estimated time

enroute (ETE) and velocity made good (VMG, or the rate you are closing in on

your destination) are displayed at the bottom of the page.

As you head toward the destination, the middle section of the page gives you

visual guidance to your waypoint on a graphic highway, which displays the route

and nearby waypoints on screen. The moving arrow below the highway always

points to the destination waypoint relative to the direction youre moving. The

line down the center of the highway represents your desired track, while the bot-

tom of the page provides a graphic indication of your crosstrack error (the dis-

tance and direction you are off course) according to the scale at the bottom right

of the page.

Whenever the GPSMAP 185 Sounder is in simulator mode, you can adjust your

speed and course from the navigation page using the

keypad. As you head

toward each waypoint in the tour route, try adjusting your boat speed and course

to get a feel for how the highway works.

A. In this example, our boat is off course to the

left by about 1/8th of a mile (the base of the

highway map is equal to the scale selected at

the bottom right of the page). To get back on

course, steer right.

B. In this example, our boat is off course to the

right. To get back on course, steer left. A digi-

tal readout of your exact crosstrack error can

be displayed in any of the six data fields (see

page 47).

Notice that as you get off course, the highway and waypoint pointer move to

give you graphic guidance to get back on course. The scale in the lower right cor-

ner of the page represents the total distance (or the width) of the base of the high-

way display. The default graphic highway setting is 1/4 nm, but can be set for a

1/2-, 1-, 2- or 4-nm range.

To change the highway scale display:

1. Press either the Cor Dkey to increase or decrease the map scale.

Power Off

Status Page

The GPSMAP 185 Sounder status page provides a visual reference of various

receiver functions, including current satellite coverage, receiver operating mode

and current receiver accuracy. The status information will give you an idea of

what the receiver is doing at any given moment.

The sky view and signal strength bars give you an indication of what satellites

are visible to the receiver and whether or not they are being tracked. The signal

strength is shown on a bar graph for each satellite, with the satellite number

below. When a satellite is visible but not being tracked, the strength bar will not

be shown and the sky view indicator will not be highlighted.

The sky view shows a birds-eye view of the position of each satellite relative

to the receivers last known position. The outer circle represents the horizon

(track up), the inner circle 45º above the horizon, and the center point a position

directly overhead. Use the sky view to determine if there are obstructions shading

your reception of GPS signals.

keys, combined with the

keypad, let

you select zoom ranges and move the cursor. Two basic map operating modes,

position mode and cursor mode, determine what cartography is shown on the

map display. Position mode pans the cartography to keep the present position

marker within the display area, while cursor mode pans the cartography to keep

the cursor within the display area.

The GPSMAP system will always power up in the position mode, with your

vessel centered on the map display.

 Whenever sufficient map coverage is not available to keep the boat centered, the

boat icon will move toward the edge of the display.

 If the boat icon attempts to go off the display, the zoom level may need to be

adjusted to keep cartography on screen.

Whenever the

 Whenever the cursor reaches the edge of the display, the map will scroll

forward under the cursor. Keep in mind that the boat icon will move with the map

scrolling and may go off the display screen (you may not be able to see your present

position).

 When the cursor is stationary, a fixed coordinate position will appear in the posi-

tion field. Note that the distance and bearing will change as the boats position

changes.

 Whenever you zoom in cursor mode, the cursor will be centered on screen.

Creating and Using Waypoints

The GARMIN GPSMAP 185 Sounder stores up to 250 alphanumeric waypoints

with a user-defined icon and comment available for each waypoint. Waypoints can

be created using three basic methods:



key used primarily for marking your present position, the

key

also provides options that allow you to select a map or navaid position from

the map display.

 Graphically allows you to define a new waypoint position from the map or

sounder display using the cursor.

 Text Entry allows you to enter a new waypoints position coordinates man-

ually (from a chart, etc.) or by referencing its bearing and distance from a

Creating Waypoints/

Waypoint List

Going to a Destination

The GPSMAP 185 Sounder provides four ways to navigate to a destination:

GOTO, MOB, TracBack and route navigation. The easiest method for selecting a

destination is the GOTO function, which lets you select a destination waypoint

and quickly sets a direct course from your present position. The

key can be

used in three ways: from a list of waypoints, graphically from the map display and

from a list of GOTO options. Pressing the

key once shows a list of all way-

points in memory, from which you can select a single destination waypoint.

To activate a GOTO from the waypoint list:

1. Press the

key.

2. Select a waypoint and press

Selecting a GOTO Graphically

Pressing the

key twice allows you to graphically select an on-screen way-

point, navaid or cursor position as a destination. A graphical GOTO may be used

to select one of three options from the map display: an existing waypoint, an on-

screen navaid, or a cursor position. If you are selecting a navaid or a new position

as the GOTO destination, the GPSMAP 185 Sounder will automatically create or

move the waypoint named MAP at the navaid or map position.

To activate a GOTO from the map display:

1. Press the

key twice.

2. To select an existing user waypoint, highlight the waypoint on screen and press

3. To select a navaid, highlight the navaid on screen and press

. The GOTO new way-

point page will appear, displaying the navaid position as a MAP waypoint, with the navaid

symbol and text as the default icon and waypoint comment. Press

to save the way-

point and begin navigation.

4. To select a cursor position as your destination, move the arrow cursor to the desired posi-

tion and press

. The GOTO new waypoint page will appear and display the position as

the MAP waypoint. Press

to save the waypoint and begin navigation.

SECTION

GOTO/MOB

Selecting a GOTO

Destination

A. Press GOTO once to select a destination from a list

of waypoints.

B. Press GOTO twice to select a destination waypoint

with the map cursor. If you are not selecting an

existing waypoint as your destination, a new way-

point named MAP will be created. Keep in mind

that the MAP waypoint will be overwritten for each

MAP GOTO. This allows you to navigate to on-

screen navaids without permanently storing the

navaid as a waypoint. If you want to save the MAP

waypoint, rename it following the steps on page 39.

GOTO Key Options

The GOTO options page provides a list of additional GOTO options that let

you start a TracBack route, select a destination waypoint from the nearest way-

points list, select a route to navigate, or cancel the current GOTO destination.

To display the GOTO options:

1. Press

To select a menu option:

1. Highlight the desired option and press

The following options are available:

 Start TracBack? allows you to create and start navigation of a TracBack route

To stop navigation to the MOB position:

1. Press the

key, followed by

, to display the GOTO options page.

2. Select the Cancel GOTO option and press

TracBack Navigation

The third method of navigating to a destination is by using the GPSMAP 185

Sounders TracBack feature. The TracBack function allows you to retrace your

path using the track log automatically stored in the receivers memory, which will

eliminate the need to store waypoints along the way. TracBack routes are created

by reducing your track log into a route of up to 30 waypoints and activating an

inverted route along those points. Once activated, a TracBack route will lead you

back to the oldest stored track log point, so its good idea to clear the existing

track log at the start of your current trip (e.g., your dock) before you get started.

To clear the track log and define a starting point for a TracBack route:

1. Press the

key twice to display the main menu page.

2. Highlight the Track option and press

3. Select the Delete Track? option and press

To activate a TracBack route:

1. Press the

key.

2. Highlight the Start TracBack? option and press

Once a TracBack has been activated, the GPSMAP 185 Sounder will take the

track log currently stored in memory and divide it into segments called legs. Up

to 30 temporary waypoints (e.g. T001) will be created to mark the most significant

features of the track log in order to duplicate your exact path as closely as possi-

ble. To get the most out of the TracBack feature, remember the following tips:

 Always clear the track log at the point that you want to go back to (dock, etc.).

 The RECORD option on the track log setup page must be set to Fill or Wrap.

 There must be at least two track log points stored in memory to create a TracBack route.

 If there are not enough available waypoints in memory to create a TracBack route, you

will be alerted with a waypoint memory full message, and the receiver will use available

waypoints to create a route with an emphasis on the track log closest to the destination.

 If the track log interval is set to the Time option, the route may not follow your exact

path (keep the interval set to resolution for best performance).

 If the receiver is turned off or satellite coverage is lost during your trip, the TracBack will

draw a straight line between any point where coverage was lost and where it resumed.

 If your track logs changes in distance and direction are too complex, 30 waypoints may

not mark your path accurately. The receiver then assigns the 30 waypoints to the most

significant points of your track, and simplifies segments with fewer changes in direction.

 Whenever a TracBack route is activated, the receiver will automatically erase any tempo-

rary waypoints (e.g., T001) that are not contained in routes 1-20. If there are temporary

waypoints stored in routes 1-20, the receiver will create any new temporary waypoints

using the first three digit number available. 61

A. The TracBack feature uses your track log to

create a route back to where you started.

B. Once a TracBack is activated, the track log is

divided into segments using temporary way-

points, and an inverted route is activated

back to the oldest track log point in memory.

Using Micro G-chart Cartography

Once a Micro G-chart cartridge has been inserted, the map coverage outlines for

the cartridge will automatically appear on-screen. Keep in mind that the display

will not automatically scroll to the map area or zoom to a level where you can see

the coverage outlines. If you do not immediately see the outlines, scroll the cursor

to the broad geographic area covered by the chart and zoom out to another map

scale.

The large outlined box shown is the main chart, which serves as the boundary

area for the entire cartridge. The small outlined box inside the main box are sub-

charts, which provide more detailed coverage of the area indicated. To view the

detailed cartography of any subchart, scroll the cursor to the subchart outline and

use the

key to zoom in to smaller range scales. If the map outlines still do not

appear, check the Map Outlines setting on the map options page to make sure

they are set to appear (see page 40).

Whenever you zoom past the usable range of the current electronic chart, the range

field will display Ovr Zm or No Map. These warnings indicate that although you

may still have cartography, you should exercise extreme caution using the data. See

page 39 for more information on Overzoom and No Map modes.

When a Micro G-chart cartridge is installed, the GPSMAP 185 Sounders system

will automatically use the best available chart for display. As you enter and exit

various subcharts, the system will automatically display the appropriate chart for

the area you are in. When you leave the area covered by the main map of a car-

tridge, the GPSMAP 185 Sounder will default back to using the built-in 64 nm

database if it is available at the current scale.

If you are not seeing certain map items (navaids, depth contours, etc. on

offshore cartridges; highways, boat ramps, etc. on inland cartridges), check the

map configuration settings available from the map options page.

Installing the GPSMAP 185 Sounder

The GPSMAP 185 Sounder must be properly installed according to the follow-

ing instructions to get the best possible performance. Included with your sounder

is GARMIN power/data/transducer cable (part no. 320-00089-00) and GARMIN

transducer with cable, which must be used to comply with FCC regulations. To

complete the installation, youll need the appropriate fasteners and a 1 x 14-

thread marine antenna mount available at most marine dealers.

Mounting the GPS antenna

The antenna should be mounted in a location that has a clear, unobstructed

view of the sky in all directions to ensure the best reception. Avoid mounting the

antenna where it will be shaded by the boats superstructure, a radome antenna,

or mast. Sailboat users should avoid mounting the antenna high on the mast to

prevent inaccurate speed readings caused by excessive heeling. Most marine VHF

and loran antennas will not seriously degrade the GPS antennas reception. Never

paint the antenna or clean it with harsh solvents.

The GARMIN antenna screws directly onto any standard 1 x 14-thread anten-

na mount. If you need to raise the antenna to avoid shading, try using a 1 x 14-

thread extension mast available at most marine dealers.

To install the GPS antenna:

1. Screw the antenna directly onto the 1 x 14-thread mount.

2. Route the cable to the mounting location of the display unit. Use the appropriate tie-

wraps, fastners and sealant to secure the cable along the route and through any bulk-

head or deck.

3. Once the GPSMAP 185 Sounder unit has been installed, connect the cable to the anten-

na connector on the back of the display unit. Make sure that you turn the antenna cable

connector 1/4 turn clockwise to lock the cable into place.

SECTION

APPENDIX

Installation

It is possible to route the coaxial cable either through, or

outside the antenna mount. The BNC connector on the

coaxial cable can be removed, and the coaxial cable

shortned to ease installation. If the BNC connector is

removed it must be replaced with a new BNC connector.

Mounting the GPSMAP 185 Sounder Unit

The GPSMAP 185 Sounders compact, waterproof case is suitable for mounting

in exposed locations or at the nav station. The unit comes with a gimbal bracket

that can be used for surface or overhead mounting. When choosing a location for

the display unit, make sure you consider the following conditions:

 There should be at least a 3 (5 cm) clearance behind the case to allow connection of the

antenna, power/data cables.

 You should provide adequate clearance for the Micro G-chart cartridge cover to swing

open freely. You may have to swivel the unit to get a firm grip on the cartridge.

 The mounting surface should be heavy enough to support the unit and protect it from

excessive vibration and shock.

To install the GPSMAP 185 Sounder unit:

1. Place the mounting bracket in the desired location.

2. Mark and drill the four mounting holes for the fastener you are using.

3. Fasten the bracket to the surface using the appropriate fastener.

4. Insert the GPSMAP 185 Sounder into the mounting bracket. The bracket is designed for a

tight fit to provide additional support when swiveling the unit.

5. Screw the two mounting knobs through the bracket and into the display case.

6. Connect the power/data/transducer and antenna cables to the back of the unit, making

sure the locking rings are fully tightened on both connectors.

SECTION

APPENDIX

Installation

The mounting bracket can be rotated, allowing

the unit to be mounted overhead or on a verti-

cal surface.

To flush mount the GPSMAP 185 Sounder:

1. Remove the four M5 screws from the back of the unit and remove the mounting

bracket .

2. Using the mounting template provided in the box, determine the location where you

want to mount the unit and tape the template in place.

3. Using a hammer and center punch, mark the centers of the relief hole and mounting

screw holes.

4. Using a drill and 2.75 hole saw, cut the center relief hole from the panel. Drill the four

0.25 screw holes, using a 1/4 drill bit.

5. From the front, place the GPSMAP 180 into the relief hole until the unit rests flush

against the mounting surface.

6. Secure the unit to the mounting surface using M5 screws. Note: For thick mounting sur-

faces, insert the M5 screws directly thru the four drilled holes (figure 1). For thin panels,

place the mounting bracket on the back side of the panel for more support (figure 2).

7. Attatch the power/data/transducer cable and antenna connectors.
