NMEA 2000 Network Connection

You can connect the Garmin Signal™ VHF radio to your NMEA 2000® network using the NMEA port, to exchange information with other marine devices.

NOTE: The Garmin Signal VHF 400/220 radio is not powered by the NMEA 2000 network.

The Garmin Signal VHF 400/220 radio shares the following data with chartplotters or other connected NMEA 2000 devices.

  • Your GPS position.

  • DSC distress and position information from other vessels.

  • AIS information received from other vessels.

Additional features, such as initiating distress calls, may be available depending on your chartplotter model. See the Owner's Manual for the chartplotter for more information.

For information on setting up a NMEA 2000 network on your boat, see the Technical Reference for Garmin® NMEA 2000 Products at garmin.com/manuals/nmea_2000.
