I recently bought a used powerdrive 65 with autopilot. The guy I bought it from didn't have the manual. When I was using it last time the autopilot light would start blinking and it wouldn't respond when I tried to go left or right. If I disconnect and re-connect the battery cable it works fine for a while then it does it again. I downloaded a manual from Minn Kota, but it doesn't have anything about that problem in the troubleshooting section. I figured this would be the place to get some answers. Also i was thinking of buying a Lowrance lms522c, just wondering about some opinions that people might have about that particular unit. Thanks, Bob.
