tion Report pages. The Name field is only available in the GPS. Names cannot be sent like the MMSI
numbers to other DSC users.
DSC Setup
Garmin chartplotters have the ability to turn DSC ‘On’ or ‘Off’. This option is beneficial for users
who have more than one GPS chartplotter. If you want only DSC to display on a particular chartplotter,
turn DSC off on the remaining Garmin chartplotters that support DSC.
