Hi Mark,
The only “modern” STC’d autopilot available for the Meyers 200 is the Century 2000. It’s not cheap and can be finicky at times.
If you can hold out for a while, TruTrak should have an option for us. Likely available next year. It’s a true digital autopilot with all kinds of modern features. And, at only $5,000 it’s an amazing deal!
