Man-Overboard Distress Calls Initiated from a VHF
Radio
When the chartplotter is connected to a compatible VHF radio
with NMEA 2000, and you initiate a man-overboard DSC
distress call from the radio, the chartplotter shows the man-
overboard screen and prompts you to navigate to the man-
overboard point. If you have a compatible autopilot system
connected to the network, the chartplotter prompts you to start a
Williamson’s turn to the man-overboard point.
If you cancel the man-overboard distress call on the radio, the
chartplotter screen prompting you to activate navigation to the
man-overboard location disappears.
Man-Overboard and SOS Distress Calls Initiated from
the Chartplotter
When your chartplotter is connected to a Garmin NMEA 2000
compatible radio and you mark an SOS or man-overboard
location, the radio shows the Distress Call page so you can
quickly initiate a distress call.
For information on placing distress calls from your radio, see the
VHF radio owner’s manual. For information about marking an
MOB or SOS location, see Marking an SOS Location, page 8.
Position Tracking
When you connect the chartplotter to a VHF radio using NMEA
0183, you can track vessels that send position reports.
This feature is also available with NMEA 2000, when the vessel
sends the correct PGN data (PGN 129808; DSC Call
Information).
Every position report call received is logged in the DSC list
(DSC List, page 26).

Viewing Vessel Trails on the Chart
You can view trails for all tracked vessels on some chart views.
By default, a black line indicates the path of the vessel, a black
dot indicates each previously reported position of a tracked
vessel, and a blue flag indicates the last reported position of the
vessel.

Individual Routine Calls
When you connect the chartplotter to a Garmin VHF radio, you
can use the chartplotter interface to set up an individual routine
call.
When setting up an individual routine call from your chartplotter,
you can select the DSC channel on which you want to
communicate. The radio transmits this request with your call.
Selecting a DSC Channel
NOTE: The selection of a DSC channel is limited to those
channels that are available in all frequency bands. The default
channel is 72. If you select a different channel, the chartplotter
uses that channel for subsequent calls until you call using
another channel.
