Digital Selective Calling
Networked Chartplotter and VHF Radio
Functionality
If you have a NMEA 0183 VHF radio or a NMEA 2000 VHF
radio connected to your chartplotter, these features are
enabled.
• The chartplotter can transfer your GPS position to your radio.
If your radio is capable, GPS position information is
transmitted with DSC calls.
• The chartplotter can receive digital selective calling (DSC)
distress and position information from the radio.
• The chartplotter can track the positions of vessels sending
position reports.
If you have a Garmin NMEA 2000 VHF radio connected to your
chartplotter, these features are also enabled.
• The chartplotter allows you to quickly set up and send
individual routine call details to your Garmin VHF radio.
• When you initiate a man-overboard distress call from your
radio, the chartplotter shows the man-overboard screen and
prompts you to navigate to the man-overboard point.
• When you initiate a man-overboard distress call from your
chartplotter, the radio shows the Distress Call page to initiate
a man-overboard distress call.

Turning On DSC

Select Settings > Other Vessels > DSC.

DSC List

The DSC list is a log of the most recent DSC calls and other
DSC contacts you have entered. The DSC list can contain up to

the first call in the call list.

Viewing the DSC List

Before you can view the DSC list, the chartplotter must be
connected to a VHF radio that supports DSC.
