Consider a Simrad TP32 if you have NMEA0183 interfacing. I think the Simrad pilots are very good. The TP32 has essentially the same control circuit as my Simrad WP30 Wheel Pilot. The TP32 is self-contained and does not require any separate components.
I love my WP30! I’ve got 20 years use out of my WP30 on my 35-1 and it’s still going strong. (Disclaimer: I put a second WP30 on last month but the old one was still fine. I keep it as a spare.). The new one drove us 100+ miles waypoint to waypoint over the weekend without a hiccup. My WP30 does steer to course using the integral fluxgate as well as steer to waypoint and steer to wind angle via NMEA0183 interface. I use a Noland NMEA0183 multiplexer. Used TP32’s can be found on eBay. New ones are under $700. Dennis C. Touché 35-1 #83 Mandeville, LA
