INTRODUCTION > CARE INFORMATION

Care Information

Cleaning the Unit

The GPSMAP 182/182C 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 182/182C 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.A. at 800/800-1020 or
Garmin Europe at 44/0870-8501241.

Storing the GPSMAP 182/182C

Do not store the GPSMAP 182/182C 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.)

BASIC OPERATION

Initializing the Receiver

The first time you turn on the GPSMAP 182/182C, the receiver
must be given an opportunity to collect satellite data and
establish its present location. To ensure proper initialization, the
GPSMAP 182/182C is shipped from the factory in AutoLocate
mode.

Before you initialize, make sure the GPSMAP 182/182C unit and

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 182/182C 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.

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 182/182C 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

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, on-screen map items 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
182/182C 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 182/182C
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.

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.

BASIC OPERATION > DSC

DSC

The DSC tab on the Main Menu allows you to control and set up
the Digital Selective Calling (DSC) features on the GPSMAP 182/
182C.

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 182/182C 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, refer to “Connecting the
Power and Data” on page 98.

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. To use DSC, a user
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 182/182C receives a Distress Call from
a connected DSC-enabled VHF radio, an alert message and
notification page appear, and an alarm tone sounds. Distress Calls
are shown in the DSC Call List and Log with a checkered symbol.

22 GPSMAP 182/182C 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 appears, 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 caller’s
location on a map, select the Show Map button. To create a
waypoint at the caller’s location, select the Create Wpt button. To
close the Notification Page, press the QUIT key.

To review a call or log entry:

1. Press Menu twice.

2. Open the Call List or Log from the DSC tab.
