Your responses echo what I have been reading and hearing. There are not many non volatile memory units available. My current unit is a Clarion, over 10 years old, and I never had a memory loss or battery drain problem so I wasn't aware of the issue.

There is still hope that the head unit is fine and the problem is with the wiring or the amplifier. I don't think it's a speaker problem because ALL the cockpit speakers cut out at the same time. The bow speakers work fine because they are on a separate channel. It's being checked out now.

One good thing, the boat is going to be valeted so it's on a trailer. The bilge pump will not be using any power, not that it was usually needed that much anyway.

I wish I knew what an acceptable value for memory retention load was to allow me to go two or three weeks without worrying about the battery being too weak to start the boat. Then I could ask the manufacturers what their specs are.
