I did the NMEA2000 conversions for the auto pilot and VHF radio when I installed the TZT unit and they all are talking well together. I need to check to see if I have the RSA message enabled. When I looked for rudder angle on the message setup for the NavPilot, as I recall it just said "Furuno Specified" or something like that. I didn't see a message string for rudder angle. I'll check.
Thanks,
