6-disk CD Changer resets on its own.

[PlazaEJ]

Battery seems to be in good condition. At least that's what shows on my tester.
RAP works fine. I use it often, when eating lunch in my truck.
I've tried to pay attention to circumstances, preceding the resets. But, I'm not sure what else to pay attention to.
Clock never resets. Radio presets never change. When I come back to start the truck, the CD changer resets to Disk 1 Track 1, for no apparent reason. (And, no. It's not going from the last disk to the first.)
Any other ideas, as to the cause?

This is happening to me intermittently. Has there ever been a solution found for this?

My clock resets randomly on mine. My uncle who is an electrical engineer for gm told me it had to do with voltage drop/bad grounding issues. He told me to check engine to body/chassis grounds and body to chassis grounds. Other than that he didn't know what it was.
Since then I did the "big 3" ground wire thing and it hasnt happened since, knock on wood. That was last summer.
