Just took delivery of new 21 and absolutely love it. My son, a seasoned boater with a huge boat, has insisted I get an autopilot. We need some advice and what/how to interface with the new Volvo 30 hp. Any suggestions on what will work? We have the new 741 Garmin from you. also looking for inexpensive night vision. We are 75 and night camera will help. any thoughts you can share?
