What is "DSC+"? Digital Selective Calling is categorized by class. The GX1150 radio
is qualified to DSC
Class-D. The radio has NMEA-0183 input and output.
A Garmin GPSMAP 78 has a NMEA-0183 interface. To use it, a $36 accessory cable is needed:
On the basis that both devices support NMEA-0183, they should be able to be interconnected using that protocol.
