Comnav Autopilot, backup battery replacement?
I have a Comnav 1420 auto pilot that works fine every time i go thtough the setup procedure. However after being powered off for several days it needs to be set up again. The manual says it needs "to be returned for service". I am pretty sure it needs the memory backup battery replaced. Anybody ever done this? Next time i am at the boat with some time i will thake the cove off and look for said battery
