Networked Chartplotter and VHF Radio Functionality
When you connect a compatible VHF radio 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.
For information about installing and connecting a VHF radio, see the VHF radio installation instructions.

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 100 entries. The DSC list shows the most recent call from a boat. If a second call is received from
the same boat, it replaces 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.
