Position Tracking
When you connect your Garmin chartplotter to a VHF radio using NMEA 0183, you can track
vessels that send position reports. This feature is also available with NMEA 2000, provided that the
vessel sends the correct PGN data (PGN 129808; DSC Call Information).
Every position report call received is logged in the DSC List (
page 50 ).
To view a list of position reports:
1. From the Home screen, select Information > DSC List .
2. Select from the following options:
Call with Radio —set up an individual routine call ( page 52 ) with the radio to call the vessel
that sent the position report. This option is only available if you are using a Garmin NMEA
2000-compatible VHF radio.
Edit —edit the vessel name and add a comment. If your radio is tracking the position of the
vessel, select Trail to show or hide the trail line for the vessel, and select Trail Line to change
the line color.
Clear Report —delete the call report.
Navigate To —Go To or Route To the location sent with the position report ( page 21 ).

Next Page/Previous Page —toggle between details of the position report and a Navigation
Chart marking the location.
