Receiving Distress Calls
If your Garmin chartplotter and VHF radio are connected via NMEA
0183 or NMEA 2000, your chartplotter alerts you when your VHF
radio receives a DSC distress call. If position information was sent
with the distress call, that information is also available and recorded
with the call.
The symbol designates a distress call in the DSC List and marks
the position of a vessel on the Navigation chart at the time the DSC
distress call was sent.

1. Select
Review
