Description  
AIS alerts you to area traffic. When connected to an external AIS  
device, the chartplotter can show some AIS information about other  
vessels that are within range, that are equipped with a transponder,  
and that are actively transmitting AIS information. The information  
reported for each vessel includes the Maritime Mobile Service  
Identity (MMSI), the location, the GPS speed, the GPS heading,  
the time that has elapsed since the last position of the vessel was  
reported, the nearest approach, and the time to the nearest approach.

direction in which the triangle is pointing indicates the  
direction in which the AIS vessel is moving.  
Target is selected.  
Target is activated. The target appears larger on the chart.  
A green line attached to the target indicates the heading of  
the target. The MMSI, speed, and direction of the vessel  
appear beneath the target, if the details setting is set to  
Show (page 44). If the AIS transmission from the vessel is  
lost, a message banner appears.  
Target is lost. A green X indicates that the AIS transmission  
from the vessel is lost, and the chartplotter displays  
a message banner asking whether the vessel should  
continue to be tracked. If you discontinue vessel tracking,  
the lost target symbol disappears from the chart or the 3D  
chart view.

The projected course of an activated AIS target appears as a dashed

If an activated AIS target is not transmitting speed information, or  
if the vessel is not moving, a projected course line does not appear.  
Changes in the speed, the course over ground, or the rate-of-turn  
information transmitted by the vessel can impact the calculation of  
the projected course line.

Man-Overboard Distress Calls Initiated  
from a VHF Radio  
Position Tracking  
When you connect your Garmin chartplotter to a VHF radio using  
NMEA 0183, you can track vessels that send position reports. This  
feature is also available with NMEA 2000, provided that the vessel  
sends the correct PGN data (PGN 129808; DSC Call Information).  
When your Garmin chartplotter is connected to a Garmin NMEA  
2000-compatible radio and you initiate a man-overboard DSC  
distress call from your radio, your Garmin chartplotter displays the  
man-overboard screen and prompts you to navigate to the man-  
overboard point. If you have a Garmin autopilot system connected  
to the network, your chartplotter prompts you to start a Williamson  
turn to the man-overboard point.  
Every position report call received is logged in the DSC list  
(page 41).  
To view a list of position reports:  
1. From the Home screen, select Information > Other Vessels >  
DSC List.  
If you cancel the man-overboard distress call on the radio, the man  
overboard screen no longer appears.  
2. Select from the following options:  
Select Call with Radio to set up an individual routine call  
with the radio to call the vessel that sent the position report.  
This option is only available if you are using a Garmin NMEA  
2000-compatible VHF radio.  
Man-Overboard Distress Calls Initiated  
from the Chartplotter  
When your Garmin chartplotter is connected to a Garmin NMEA  
2000-compatible radio and you activate navigation to a man-  
overboard location, the radio displays the Distress Call page to  
initiate a man-overboard distress call. On the radio, press and hold  
the DISTRESS key for at least three seconds to send the distress  
call.  
Select Edit to edit the vessel name and the vessel symbol,  
and to add a comment. If your radio is tracking the position  
of the vessel, select Trail to show or hide the trail line for  
the vessel, and select Trail Line to change the line color.

Caring for the Unit  
The case is constructed of high-quality materials and does not  
require user maintenance, except cleaning.  
waypoint Memory full—you have saved the maximum number  
of waypoints. Delete unwanted waypoints to make space for new  
entries.  
Cleaning the Case  
Clean the unit’s outer casing (except for the screen) using a cloth  
dampened with a mild detergent solution and then wipe dry. Avoid  
chemical cleaners and solvents that may damage plastic components.  
Capturing Screenshots  
You can capture a screenshot of any screen displayed on your unit as  
a bitmap (.BMP) file and then transfer it to your computer.  
To capture screenshots:  
1. Insert an SD card into the SD card slot on the front of the unit.  
Cleaning the Screen  
The lens on the screen is coated with a special anti-reflective coating  
that is sensitive to skin oils, waxes, and abrasive cleaners. Cleaners  
containing ammonia, alcohol, abrasives, or anti-grease detergents  
will harm the anti-reflective coating. It is important to clean the lens  
using an eyeglass lens cleaner (that is specified as safe for anti-  
reflective coatings) and a clean, lint-free cloth.  
2. Select Configure > System > Beeper/Display.  
3. Select Screenshot Capture to turn screenshot captures On.  
4. When you are on a screen you want to capture, press and hold  
the HOME button for at least six seconds.  
5. Select OK when the Screenshot Taken window is displayed.  
To copy the screenshots to your computer:  
1. Remove the SD card from the chartplotter and insert it into an SD  
card reader that is attached to a computer.  
2. From Windows Explorer, open the Garmin\scrn folder on the SD  
card.
