The GP1971F follows Standard NMEA 2000. Looking at the pilot it looks to support Seatalk ng (proprietary) and NMEA 2000. I would recommend you talk to Raymarine because it appears you might need some proprietary cables to have it use the stardard NMEA 2000 connections. Normally, standard NMEA 2000 items would connect up on a bus together which people would use a NMEA 2000 starter kit (like Furuno p/n AIR-033-745) and add to it from there.
