The Comnav is now strictly a backup unit (and rudder angle indicator). There is simply no comparison in their performance. The Garmin mostly keeps the crosstrack error less than ten or twenty feet, even with big cross currents. Unlike the Comnav it requires no adjusting and tunes itself to the conditions.

I believe that any of the major manufacturers (Simrad, Raymarine, and Furuno) have autopilots with similar smarts. In my opinion, the Comnav is just primitive by comparison.

You are the only person I have ever heard this from. Not that my observation of your post adds anything to the conversation, but it is true. ComNav/Sim-Tek has a stellar rep in the commercial fishing market (according to them, I admit), but my experience was top notch and I am considering replacing my Raymarine with one next year.
