Just an update. I requested that my service person look into the problem instead of returning the car (I wasn't going to accept that a satellite radio program change caused my backup camera to stop working). He fixed the problem, but this was the explaination: "It had something to do with something plugged into your USB port. I cannot explain how I fixed it, but now it is fixed."
Huh?
Well, the only thing plugged into a port was my lowly Ipod (not even an Ipod Touch, mind you). So now, I guess my IPod can cause my backup camera to puke out. (I have not plugged it back in to see what happens.)
In addition, my car was returned and all of my settings are back to the factory setting, so now I will spend another half an hour going through and figuring out what needs reset to my preferences.
I am glad it is fixed, and I know there are bugs, but really...
