I assume you have a Hydra 2000 Processor and you connected the Autopilot NMEA Input port to the NMEA Output 1 of the B&G Processor on Terminal 21/22 or 22/23 for NMEA Output 2 (see screenshot from manual).
That should work. If you have a possibility to read the NMEA datastream (6.6.2. on Screenshot), you can check if you find the wind and speed data the autopilot needs.
If it does not work I will have an FFD NMEA for sale, I will be on the boat on Eastern and be able to send it.
