Seeking advice for a Fish Finder with my Minn Kota Auto Pilot
I think you have the white head power drive trolling motor. Is that correct?
The sonar built into the motor unit of the tolling motor will not interact with the autopilot. It just gives you a more clean way to have sonar on the trolling motor instead of external transducer. The options for using the universal sonar version 1 (commonly referred to as US1) are somewhat limited to older depth finders. The newer version of universal sonar is US2.
here is a link to compatible units. You will need an adapter cable to hook up to them.
