Any Raynav autopilot with SeaTalk
will talk to your ST-60 instruments. The important part is the Seatalk buss. Not knowing what boat you have, I can't recommend exactly what one, but the AS-4000+, the AS-5000, and the AS-6000 all use SeaTalk and can talk to the ST-60 instruments. The AS-4000 has been replaced by an updated version, and that will probably work as well. You may be better off buying one on E-Bay, as most of the dealers will only have the most recent release.BTW, If you can use the AS-4000 wheel pilot, make sure that you get the AS-4000+ (plus), as it seems to be a whole lot better than teh previous version.SteveAlchemist C-320
