Daryl, I'm going with the uneducated theory that the loss of power to the unit (assuming it gets it power from the coach batteries) caused it to revert to the factory default which was...
1) XM mode
2) tuner mode
3) CD changer mode
4) Optional Video Mode (Note: must be programmed to work)
I based this seat of the pants theory on the fact that when the tech was pushing this button and that button, a screen popped up asking if you want to turn on the camera!! And since I never turned off the camera mode, I'm gonna blame it on the power loss due to the battery change out! That's my story and I'm sticking to it! (unless someone proves me wrong then I'll blame it on "The Twilight Zone")
