PREFACE
Preface
Congratulations on choosing one of the most advanced marine navigation systems available! The GARMIN GPSMAP 180 combines the proven performance of
GARMIN GPS with powerful Micro G-Chart electronic charting for detailed cartography and plotting wherever you cruise.
To get the most out of your new navigation system, take the time to go through
this operator’s manual and learn the operating procedures for your unit. This
manual is broken down into two sections for your convenience.
Getting Started introduces you to the GPSMAP 180 and provides a tutorial that
will help you become more familiar with the unit. This part will provide you with
a basic working knowledge necessary to use the unit to it’s fullest
potential.
The Reference portion is divided into sections that provide detailed instructions
on the advanced features and operations of the GPSMAP 180. This allows you to
concentrate on a specific topic quickly, without reading through entire portions of
text that you may not need.
An Appendix section concludes the manual with specific information needed
for custom setup, trouble shooting, and indexing.
WARNING!
The electronic chart is an aid to navigation
and is designed to facilitate the use of authorized government charts, not replace them.
Only official government charts and notices to
mariners contain all information needed for
the safety of navigation–and, as always, the
user is responsible for their prudent use.

Initializing the Receiver
GETTING STARTED
The first time you power up your new GPSMAP 180 is an important step in getting the best possible GPS performance. The receiver must be given an opportunity
to collect satellite data and establish its present position. To ensure proper initialization, the GPSMAP 180 is shipped from the factory in AutoLocateTM 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.
Initialization
Before you initialize, make sure the GPSMAP unit and antenna have been correctly
installed on your vessel according to the instructions in Appendix A.
To turn the GPSMAP 180 on:
1. Press and hold the P 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 T key.
A message alert and prompt will also appear asking you to select an initialization
method.
To view a message:
1. Press the J key.
2. Press the J key again to return to the previous page.
A
B
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 supplement to local government charts, not as a
replacement.

GETTING STARTED
Initialization
The select initialization window will appear, with the ‘select from map’ option
highlighted.
1. Press T to initialize the receiver from the built-in worldwide map.
The Map Page will appear, prompting you to select your approximate present position with the map cursor.
1. Use the R keypad to move the map cursor to a location close to your present position. If you
have difficulty identifying your exact position, press the C key to zoom in to a lower map scale.
2. Press T to confirm your selection.
The GPSMAP 180 will now begin searching for the appropriate satellites for your
present position and should acquire a fix within a few minutes. While the receiver
searches for satellites, a flashing satellite icon will appear at the left-hand side of the
status bar. A signal strength bar will appear for each satellite in view, with the appropriate satellite number under each bar. The progress of satellite acquisition is shown
in three stages:
A
B
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
Satellite Page while the receiver collects satellite data.
• 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 collecting data.
• Solid signal strength bars— the receiver has collected the necessary data and the satellite(s) is ready for use.
Once the receiver has collected information from at least three satellites, the flashing satellite icon on the status bar will quit flashing and remain solid, and the
GPSMAP 180 is ready for use.
Now that the unit is initialized, let’s turn the unit off and then begin the GettingStarted Tour.
To turn the GPSMAP 180 off:
1. Press and hold the P key for about 3 seconds, until the screen is blank.
2
GPSMAP 180 Getting-Started Tour
The GARMIN GPSMAP 180 is a powerful electronic charting/navigating system
that provides detailed chart coverage and convenient control of many advanced
features right from the map display. This tour is designed to take you through the
basic pages and functions of the system using the simulator 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 descriptions and pictures in the tour may not match your configuration.
GETTING STARTED
Power On & Screen Contrast
To turn the GPSMAP 180 on:
1. Press and hold the P 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 T key to acknowledge the mariner’s warning.
The Satellite Page will appear, and the receiver will begin to acquire satellites.
From the Satellite Page, you may also quickly adjust the screen contrast and backlighting.
To adjust the screen contrast:
1. To increase the screen contrast, press the right arrow of the R keypad.
2. To decrease the screen contrast, press the left arrow of the R keypad.
3. Press the T key to finish.
The GPSMAP 180’s three-level screen backlighting is controlled with P key,
and may be adjusted at any time from any page.

The GPSMAP 180’s Satellite 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 180’s system also features an
options page, which gives you access to other functions and features that relate to
the specific page you are viewing. To get a feel for how the options pages work,
lets put the GPSMAP 180 into simulator mode.
To place the GPSMAP 180 in simulator mode:
1. From the Satellite Page, press the O key. The options page will appear, displaying a
menu of options and functions for the Satellite Page.
2. Use the UP or DOWN arrow of the R keypad to highlight the ‘Start Simulator?’ option and
press T.
3. Press the T key to confirm the simulator warning.
Once the simulator has been started, the status field at the top of the page will
display a ‘Simulating Navigation’ status, and you’re ready to continue the rest of
the tour. Keep in mind that the GPSMAP 180 does not track satellites in simulator
mode, and should never be used for actual navigation. All the waypoint and route
planning done in simulator mode will still be retained in memory for future use.
GETTING STARTED
Page Sequence & Position Page
The Satellite Page is one of four main pages used in the GPSMAP 180’s system.
All four pages are linked together in a simple chain, which allows you to scroll
through the pages in either direction using the J and Q keys. To continue
the tour, let’s move on to the next page, the Position Page.
To scroll to the next page in sequence:
Graphic
CompassTape
1. Press the J key.
The GPSMAP 180’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 altitude 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 Satellite 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 180’s R keypad and T key
are used for data entry.

move on to the Map Page.
1. Press the J key.
The GPSMAP 180’s Map Page combines digital chartplotting with a user-selectable display of navigation data and a built-in worldwide database to 64 nm. It
will also be the page you use most to create and edit waypoints and routes. Before
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, along with geographic names,
markers and buoys that are provided by the G-chart cartridge you’re currently
using. 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 position, and perform various waypoint and route functions.
The data window, located at the top of the page, provides a user-selectable display of various navigation data, including course, speed over ground, and the
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 29.

Using the Map Cursor
GETTING STARTED
Using the Map Cursor
Working from the Map Page is a simple process that centers around the use of the
cursor. Controlled by the R 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 C 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 R keypad to move the cursor down to the first lat/lon grid
south of your boat’s position.
3. Using the R keypad to move the cursor, try following the outline of the lat/lon grid closest
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 cursor.
A
B
A. Whenever the cursor is active, the bearing
and distance of the cursor from your present
position will appear in a pop-up data window.
B. To remove the cursor and recenter your vessel on the map, press the QUIT key.
8
4. Press the Q 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 G-chartTM coverage) and create waypoints and routes. Wherever you
move the cursor, pressing Q once will return 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 180 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 permanent memory, so
you can see exactly what you’ll experience when you’re navigating with your new
GPS chartplotter.
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 M key to store our present position, so it’s time to move on to the fun
part— going to a destination. The G key, located on the left side of the keypad
above the Q key, is the primary tool used to select a destination waypoint or a
route to navigate. The G key can be used in three primary ways:
GETTING STARTED
Using the GOTO key
• Pressing G once displays a list of all waypoints in memory, from which
you can select a single destination waypoint.
• Pressing G followed by the O key provides a list of GOTO options
that lets you start a TracBackTM route, select a destination waypoint from
the nearest waypoints list, select a stored route to navigate, or cancel the
current GOTO destination.
• Pressing G twice allows you to 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 preprogrammed 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 O key is used throughout
the GPSMAP 180 system to provide context-sensitive options and functions. Let’s
give it a try by activating the practice route stored in memory for navigation:
1. Press G. 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 T).
2. Press O to display the context-sensitive options available for the GOTO
function.
3. Use the R keypad to highlight the ‘Select Route?’ option. Press T to confirm.
4. The select route page will appear, with the ‘GPSMAP TOUR’ route highlighted.
5. Press T. The Map Page will reappear and display five waypoints chained together in
a simple route, with your boat at the first route waypoint.
A
B
A. Pressing GOTO once displays a list of all waypoints 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 destination from the nearest waypoints list, or
select a route to navigate.

GETTING STARTED
Simulator Setup & Map Scales
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 simulator page is also available from any other page in the main page sequence.
To enter a boat speed:
1. Press the O key to display the map options page.
2. Use the R keypad to select the ‘Setup Simulator?’ option and press T.
3. Once the setup simulator page appears, press T to access the SOG field.
4. Use the R keypad to enter a speed of 60 knots.
5. Press T to finish, and J 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 C key to select the 16 nm scale.
A
B
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.
10
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 cartography 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 display ‘OVR ZM’ or ‘NO MAP’ to indicate that you should exercise extreme caution
using the cartography data. See page 25 and 66 for more information on map
scales and using Micro G-chart detailed cartography.
Now that we’re 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 R 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).
Once the cursor is over the TOUR3 waypoint, you’ll notice that the waypoint
symbol and name will become highlighted, and 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.
GETTING STARTED
Reviewing & Creating
Waypoints on the Map
To review the waypoint page for a selected waypoint:
1. Press the T key.
2. To return to the Map Page, press T 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 R 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 T key to capture the cursor position.
3. Use the R key to highlight the waypoint symbol field.
4. Press T to access the symbol page.
5. Press the DOWN arrow of the R keypad twice to select the wreck symbol.
6. Press T to confirm, and T again to finish.
A

12
B. In this example, our boat is off course to the
right. To get back on course, steer left. A digital readout of your exact crosstrack error can
be displayed in any of the six data fields (see
page 29).
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 graphic compass 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 bottom of the page provides a graphic indication of your crosstrack error (the distance and direction you are off course) according to the scale at the bottom right
of the page.
Whenever the GPSMAP 180 is in simulator mode, you can adjust your speed
and course from the Navigation Page using the R 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.
GETTING STARTED
Using the Navigation Page
To adjust the simulated boat speed:
1. Press the UP arrow of the R keypad to increase the speed in 5 knot/kph/mph increments. Press the DOWN arrow to decrease the speed in the same increments.
To steer the boat:
1. Press the LEFT and RIGHT arrows of the R keypad.
Notice that as you get off course, the highway and waypoint pointer move to
give you graphic guidance to get back on course. The base of the highway display
also serves as a graphic course deviation indicator (CDI), relative to the scale setting shown at the bottom right of the page. The scale setting represents the total
distance (or the width) of the base of the highway 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 the C or D key (ZOOM OUT to increase, ZOOM IN to decrease the scale).
The Navigation Page data fields may also be configured to display any of ten
different navigation values. Let’s change the VMG field to crosstrack error to provide a digital readout of the distance we’re off course.

allows you to calibrate the map display your exact physical surroundings or to correct data from older charts. Before using the map calibration function, check to
make sure that your map datum selected on the GPS matches the datum on the
chart you are using (see page 61). To calibrate the map display, you must know
exactly where you are, and understand that the correction is generally valid only in
a limited range from the point of correction.
Map calibration should only be performed while the vessel is not moving, and
should never be used to attempt SA corrections, which can degrade accuracy up to
330’ (100 meters). The maximum correction is 16,400 feet (5000m).

The GARMIN GPSMAP 180 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:
• M key– used primarily for marking your present position, the M key
also provides options that allow you to select a map or navaid position
from the map display.
• On Map– allows you to define a new waypoint position from the map display using the cursor.
• Text Entry– allows you to enter a new waypoint’s position coordinates
manually (from a chart, etc.) or by referencing it’s bearing and distance
from a stored waypoint or your present position.

Going to a Destination
GOTO/MOB
The GPSMAP 180 provides four ways to navigate to a destination: GOTO,
MOB, TracBack and route navigation. The most basic method of selecting a destination is the GOTO function, which lets you select a waypoint as your destination
and quickly sets a direct course from your present position. The G key can be
used in three ways: from a list of waypoints, directly from the map display and
from a list of GOTO options. Pressing the G key once displays a list of all waypoints in memory, from which you can select a single destination waypoint.

To stop navigation to the MOB position:
1. Press the G key, followed by O, to display the GOTO options page.
2. Select the ‘Cancel GOTO’ option and press T.
TracBack Navigation
The third method of navigating to a destination is by using the GPSMAP 180’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 track log point stored in memory, 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 O key twice to display the Main Menu Page.
2. Highlight the ‘Track’ option and press T.
3. Select the ‘Delete Track?’ option and press T.
4. Highlight the ‘Yes’ field and press T.

To activate a TracBack route:
GOTO/MOB
TracBack Navigation
1. Press the G key, followed by the O key.
2. Highlight the ‘Start TracBack?’ option and press T.
Once a TracBack has been activated, the GPSMAP 180 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 possible.
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.
A
B
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 waypoints, and an inverted route is activated
back to the oldest track log point in memory.
46
• 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 the changes of direction and distance of your track log are very complex, 30 waypoints
may not accurately mark your exact path. The receiver will then assign the 30 waypoints
to the most significant points of your track, and simplify segments with fewer changes in
direction.
• Whenever a TracBack route is activated, the receiver will automatically erase any temporary 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.
Routes
ROUTES
The last way to navigate to a destination is to create a user-defined route. The
GARMIN GPSMAP 180 system lets you create and store up to 20 reversible routes
(numbered 1-20), with up to 30 waypoints each. Routes can be created and modified right from the Map Page, allowing you to see each route on-screen as you create, review, modify, or navigate the route. All of the GPSMAP 180’s route functions are accessed through the main menu.

you from using the TracBack feature.
• Fill– a track log will be recorded until the track memory is full.
• Wrap– A track log will be continuously recorded, wrapping through the available
memory (replacing the oldest track data with new data).
• Interval— defines the frequency with which the track plot is recorded. Three interval settings are
available:
• Time– records track plot based on a user-defined time interval.
• Resolution– records track plot based upon a user-defined variance from
your course over ground. The resolution option is the default setting and
is recommended for the most efficient use of memory and TracBack performance. The distance value (entered in the interval field) is the maximum error allowed from the true course before recording a track point.

66
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 subcharts, 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 C 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 26).
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 25 for more information on Overzoom and
No Map modes.
When a Micro G-chart cartridge is installed, the GPSMAP 180’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 cartridge, the
GPSMAP 180 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 180
The GPSMAP 180 must be properly installed according to the following instructions to get the best possible performance. The GPS antenna should be installed
first, followed by the display unit. To complete the installation, you’ll need the
appropriate fasteners for your installation, and a 1” x 14-thread marine antenna
mount available at most marine dealers.
APPENDIX
Installation
SECTION
A
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 antenna mount. If you need to raise the antenna to avoid shading, try using a 1” x 14thread 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 tiewraps, escutcheon plates, and sealant to secure the cable along the route and through
any bulkhead or deck.
3. Once the GPSMAP unit has been installed, connect the cable to the antenna connector
on the back of the display unit. Make sure that you turn the antenna-connector locking
ring 1/4 turn clockwise to lock the cable into place.
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.

APPENDIX
Installation
The GPSMAP 180’s water-resistant case is suitable for mounting in exposed
locations or at the nav station. The unit comes with a mounting bracket and a
gimbal mount to allow 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” (7.5 cm) clearance behind the case to allow connection of
the antenna and power/data cables.
• The unit should not be mounted where it is exposed to excessive temperatures for
extended periods (see page 71).
• You should provide adequate clearance for the Micro G-chart cartridge to slide out completely.
• The mounting surface should be heavy enough to support the unit and protect it from
excessive vibration and shock.
To surface mount the GPSMAP unit:
1. Place the gimbal mount in the desired location.
2. Mark and drill the four mounting holes for the fastener you are using.
3. Fasten the gimbal mount to the surface using the appropriate fasteners.
4. Insert the GPSMAP 180 into the gimbal mount. The mount is designed for a tight fit to
provide additional support when swiveling the unit.
5. Screw the two mounting knobs through the gimbal mount and into the mounting bracket.
6. Connect the power/data and antenna cables to the back of the unit, making sure the locking rings are tightened on both connectors.
NOTE: The mounting bracket can be rotated 360°, allowing the GPSMAP 180 to
be mounted on a vertical surface or overhead.
68
To flush mount the GPSMAP 180
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.

Almanac Data—The satellite constellation information (including location and health of
satellites) that is transmitted to your receiver from every GPS satellite. Almanac data must
be acquired before GPS navigation can begin.
Bearing (BRG)—The compass direction from your position to a destination.
Course Over Ground (COG)—Direction of movement relative to a ground position.

Crosstrack Error (XTK)—The distance you are off a desired course in either direction.
Desired Track (DTK)—The compass course between the “from” and “to” waypoints.
Differential GPS (DGPS)—An extension of the GPS system that uses land-based radio beacons to transmit position corrections to GPS receivers.
Estimated Time of Arrival (ETA)—The time of day of your arrival at a destination.
Estimated Time Enroute (ETE)—The time remaining to your destination at your present
speed.
Grid—A coordinate system that projects the earth on a flat surface, using square zones for
position measurements.
Ground Speed (SOG)—The velocity you are traveling relative to a ground position.
Latitude—A north/south measurement of position perpendicular to the earth’s polar axis.
Longitude—An east/west measurement of position in relation to the Prime Meridian, an
imaginary circle that passes through the north and south poles.
Position—An exact, unique location based on a geographic coordinate system.
Turn (TRN)— The difference and direction in degrees between the bearing to your destination and your course over ground. The TRN value is used to indicate what direction, and
how many degrees, to turn to get back on course.

Universal Time Coordinated (UTC)— The time of day at the prime meridian (0º longitude) in Greenwich, England.
Universal Transverse Mercator- (UTM)— A grid coordinate system that projects global sections onto a flat surface to measure position in specific zones.
Velocity Made Good (VMG)—The speed you are traveling in the direction of the destination.
Waypoint—A specific location saved in the receiver’s memory.

Loran TD Position Format
When creating new waypoints using Loran TD coordinates you must set
the correct loran chain number and secondary stations in the Setup TD
field before storing the waypoint. After the waypoint is stored in unit
memory, it will always reference the loran chain number and secondary
stations currently selected in the Setup TD field. If you enter a different
loran chain number or change the secondary stations in the Setup TD
field, the active waypoint information will reflect those changes. Since
the GPSMAP 180 does not rely on the loran signal for navigation, it can
reference a different GRI chain and/or secondary stations and still navigate to the location stored in memory.
To change the Setup TD settings:
1. Highlight the ‘Setup TD’ field and press T.
2. Select the field to change and press T.
3. Highlight the new setting and press T..
