INTRODUCTION > CARE INFORMATION

Care Information

Cleaning the Unit

The GPSMAP 192C is constructed of high quality materials and
does not require user maintenance other than cleaning. Clean the
unit using a cloth dampened with a mild detergent solution and
then wipe dry. Avoid chemical cleaners and solvents that can
damage plastic components.

Immersing the Unit in Water

The GPSMAP 192C is waterproof to IEC Standard 60529 IPX7.
It can withstand immersion in 1 meter of water for 30 minutes.
Prolonged submersion can cause damage to the unit. After
submersion, be certain to wipe and air dry the unit before reuse.

To resolve problems that cannot be remedied using this manual,
contact Garmin Product Support in the U.S. at 800/800-1020 or
Garmin Europe at 44/0870-8501241.

Storing the GPSMAP 192C

Do not store the GPSMAP 192C where prolonged exposure to
temperature extremes can occur (such as in the trunk of a car) as
permanent damage can result. User information, such as waypoints
and routes are retained in the unit’s memory without the need for
external power. It is always a good practice to back up important
user data by manually recording it or downloading it to a PC
(transferring it to MapSource.)

iv GPSMAP 192C Owner’s Manual

BASIC OPERATION

Initializing the Receiver

The first time you turn on the GPSMAP 192C, the receiver
must be given an opportunity to collect satellite data and
establish its present location. To ensure proper initialization, the
GPSMAP 192C is shipped from the factory in AutoLocate mode.

Before you initialize, make sure the GPSMAP 192C unit and
antenna have been correctly installed on your vessel according to
the instructions in the Appendix. Install the antenna in a location
with a clear and unobstructed view of the sky.

A full-screen GPS Information page is displayed after you press
ENTER to acknowledge the Warning page. The page goes away
after the unit gets a position fix or you press either ENTER
or QUIT. The page can be disabled and enabled on the Main
Menu—Pages tab (see page 63).

To turn on the GPSMAP 192C:

1. Press and hold the POWER key until the power tone

2. When the self-test is complete, press ENTER to agree and

The GPS Information page appears as the receiver begins acquiring
satellites.

GPSMAP 192C Owner’s Manual 1

BASIC OPERATION > INITIALIZING THE RECEIVER

To graphically initialize the GPSMAP 192C:

1. Press MENU twice for the Main Menu. Press Up or Down
on the ROCKER until the GPS tab is highlighted, then press
MENU one time.

2. Using the ROCKER, highlight Initialize Position, and press
ENTER. The Initialize Position page appears, prompting you
to select your approximate location with the map pointer.

3. Use the ROCKER to move the map pointer to your
approximate location within 200 miles. If you have difficulty
identifying your location, press and release the IN key to
see the next lower map range.

4. When you have determined your approximate location on
the map, press ENTER.

NOTE: This does not calibrate the unit in any way, but rather

helps to speed up the initial satellite acquisition. If the unit
displays “Ready 2D or 3D” during this process, it is not
necessary to initialize the unit.

The GPSMAP 192C now begins searching for the appropriate
satellites for your region and should acquire a fix within a few
minutes. When viewing the GPS tab on the Main Menu, a signal
strength bar for each satellite in view appears on the bottom of the
page, with the appropriate satellite number under each bar.

• 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) are ready for use.

When the receiver has collected information from at least three
satellites, the top of the screen displays either “Ready 2D or 3D”,
and the GPSMAP 192C is ready for use.

2 GPSMAP 192C Owner’s Manual

Simulator Mode

Simulator Mode turns the GPS receiver off for use indoors or
practice. Any of the functions discussed in the following pages
can be performed in Simulator Mode. While in Simulator Mode, a
“Running Simulator” message appears after 2 minutes of inactivity.
Keep in mind that the GPSMAP 192C does not track satellites in
Simulator Mode, and this mode should never be used for actual
navigation. All the waypoint and route planning completed in
Simulator Mode is retained in memory for future use.

BASIC OPERATION > CREATING AND USING WAYPOINTS

Creating and Using Waypoints

The GPSMAP 192C stores up to 3,000 alphanumeric waypoints
with a user-defined symbol, comments, and depth available for
each waypoint. Waypoints can be created using two basic methods.

ENTER/MARK Key—marks your present location, and provides
options to select a map position or map item from the map display.
You can also enter a new waypoint’s location coordinates manually.

ENTER/MARK Key

The GPSMAP 192C’s ENTER/MARK key quickly captures your
present location to create a new waypoint. You must have a valid
position (2D or 3D) fix to mark your present position. This can be
determined by looking at the GPS tab on the Main Menu. When
you move the pointer over a map item, a highlighted description of
that item appears. You can also use this option to manually enter
waypoint coordinates.

Graphically—defines a new waypoint location from the map
display using the ROCKER.

To mark your present position:

1. Press and hold ENTER/MARK until the New Waypoint
window appears, then release it. A default three-digit name
and symbol is created for the new waypoint.

2. To accept the waypoint with the default name and symbol,
press ENTER/MARK to confirm the highlighted OK prompt.

3. To enter a different name, highlight the name field and press
ENTER/MARK, then use the ROCKER to enter the new
letter/numbers, and press ENTER/MARK when finished.

Navigating to a Destination

Using the Nav Key

The NAV key provides three ways to navigate to a destination: Go
To Point, Follow Route, and Follow Track (TracBack). When you
are actively navigating, you see a straight line that runs from your
current location to the destination. The Go To option is the easiest
method for selecting a destination. A Go To allows you to select a
destination point and quickly set a direct course from your present
location. If you have a point highlighted on a list or the map or
if you are already navigating to a point, Go To <point name>
appears in addition to Go To Point. The Go To function can be
accessed from any list of points or graphically from the map.

12 GPSMAP 192C Owner’s Manual

BASIC OPERATION > NAVIGATING TO A DESTINATION

To activate a Go To from a point list:

1. Press the NAV key. Highlight Go To Point and press
ENTER.

2. From the Find menu, highlight Waypoints and press
ENTER. (You can also choose to go to other points, such as

Cities or Tide Stations from this list.)

3. To select a waypoint from the waypoint lists, use the
ROCKER to highlight either the By Name or Nearest tab,
select a waypoint, and press ENTER.
OR
To select a waypoint from the map, highlight either the User
or Nearest tab and press MENU. With Select From Map
highlighted, press ENTER. Use the zoom IN and OUT keys
and the ROCKER to select a waypoint, then press ENTER.

Selecting a Go To Graphically

A graphical Go To can be used to select one of three items from
the map display: an existing waypoint, an on-screen map item such
as roads, rivers, cities, and navaids, or a new map point. If you are
selecting a map item as the Go To destination, the GPSMAP 192C
automatically uses the name of the map item, but the point is not
stored in the waypoint list. See page 21 for creating waypoints
using map items. If you are selecting a new map point (non-map
item) as the Go To destination, the GPSMAP 192C automatically
creates a waypoint at the pointer location.

To activate an existing waypoint or map item as a Go
To from the map display:

1. Use the ROCKER to highlight the waypoint or map item
on-screen, and press NAV.

2. You see Go To <waypoint name>, then press ENTER.
Or
Highlight the waypoint or map item, press ENTER, highlight

Go To from options at the bottom of the window, and press
ENTER.

GPSMAP 192C Owner’s Manual 13

BASIC OPERATION > NAVIGATING TO A DESTINATION

To Go To a new map point (non-map item):

1. Use the ROCKER to move the map pointer to a location.

2. Press NAV.

3. With Go To MAP Point highlighted, press ENTER.

TracBack Navigation (Navigating a Track)

The TracBack function allows you to retrace your path using the
track log automatically stored in the receiver’s memory. This
feature eliminates the need to store waypoints along the way.
TracBack routes are created by reducing your track log into a route
of up to 254 turns and activating an inverted route along those
points. When activated, a TracBack route leads you back to the
oldest stored track log point, so it’s a good idea to clear the existing
track log before you start your current trip.

You must save a track before using the Follow Track option.

14 GPSMAP 192C Owner’s Manual

BASIC OPERATION > NAVIGATING TO A DESTINATION

To activate a TracBack using the NAV key:

1. Press NAV, highlight the Follow Track option, and press
ENTER.

2. Highlight the track you want to follow, and press ENTER.

3. Choose Original, to navigate from the start to the end of
your trip, or Reverse, to navigate from the end to the start
of your trip, and press ENTER.

4. To stop TracBack navigation, press NAV, highlight Stop
Navigation, and press ENTER.

When a TracBack is active, the GPSMAP 192C takes the track log
currently stored in memory and divides it into segments called legs.

Up to 50 temporary turns (BEGIN, TURN 1, TURN 2, TURN 3,....,

TURN X, END) are created to mark the most significant features
of the track log in order to duplicate your exact path as closely as

• If the track log interval is set to the Time option, the route
can not follow your exact path. For best performance, keep
the interval set to resolution.

• If the receiver is turned off or satellite coverage is lost during
your trip, the TracBack draws a straight line between any
point where coverage was lost and where it resumed.

• If the track log’s changes in distance and direction are too
complex, 254 waypoints may not mark your path accurately.
The receiver then assigns the 254 waypoints to the most
significant points of your track, and simplifies segments with
fewer changes in direction.

For more information on setting up the Track options and saved
tracks, see pages 59.

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

• Always clear the track log at the starting point.

• The Record Mode 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.

BASIC OPERATION > DSC

DSC

The DSC page of the Main Menu allows you to control and
set up the Digital Selective Calling (DSC) features on the
GPSMAP 192C.

Digital Selective Calling (DSC) uses marine VHF radio and
Global Positioning System (GPS) technologies to transmit and
receive location information. The chartplotter repeats the call
properties received from the VHF radio on the chartplotter. The
GPSMAP 192C requires input from a DSC enabled VHF radio to
display position, and sound/display alerts from a Distress Call or
Position Report. Conversely, the VHF radio requires input from a
GPS to transmit position coordinates for a Distress Call or Position
Report. For connection information, please refer to “Connecting
the Power and Data” on page 99.

An emergency DSC Distress Call allows a vessel in trouble
to transmit a substantial amount of information in a single
transmission or call, without the need for voice communication.
When any nearby rescuer receives the DSC signal, an alarm sounds
and they immediately receive the location of the caller. The rescuer
can then choose to navigate to the caller’s location to assist, or
forward the call on to the Coast Guard. When the Coast Guard
receives the call, they can immediately access the caller’s

information (such as who they are and the type of vessel) in their
database while they are in transit to the caller’s location.

A non-emergency DSC Position Report allows mariners to
exchange and display the positions of one another. When a DSC
position is received, the mariner can choose to create a waypoint or
to show the received location on an electronic map.

Anytime a vessel receives a DSC call, they can store and quickly
navigate to that location using a Go To. This makes DSC a time
saver, especially in an emergency situation. In order to use DSC,
users must first register their VHF radio with the FCC and receive a
Maritime Mobile Service Identity (MMSI) number.

For more information about Digital Selective Calling and Maritime
Mobile Service Identity (MMSI) numbers, refer to page 103 in the
“Appendix.”

Understanding Distress Calls

When the GPSMAP 192C receives a Distress Call from a
connected DSC enabled VHF radio, an alert message and
notification page are displayed, and an alarm tone is sounded.
Distress Calls are shown in the DSC Call List, and Log with a
checkered symbol.

22 GPSMAP 192C Owner’s Manual

BASIC OPERATION > DSC

Understanding Position Reports

A Position Report is similar to a Distress Call except no alarm is
sounded. Position Reports are not broadcast to all DSC users and
are shown with a boat symbol.

When a Distress Call or Position Report is placed in the Call List
and Log, the information on the Notification page is retained.
To review a DSC call or log entry, highlight the entry and
press ENTER. The DSC Entry Review page is identical to the
Notification page with one exception, the entry can be deleted.

Receiving DSC Calls

Each time you receive a Distress Call or Position Report, a
Notification page is displayed, and the call is placed in the DSC
Call List and Log. The Notification page contains information
about the call including: the type of call (distress or position
report), the MMSI number of the caller, a user definable name,
the time and date of the call, the Bearing and Distance from your
current position, and the coordinates of the caller. To see the
callers location on a map, select the Show Map button. To create a
waypoint at the callers location, select the Create Wpt button. To
close the Notification page, press the QUIT key.

To review a call or log entry:
