I'm having the same problems. I took my truck to have the bed liner and tool box installed. I backed out of parking lot at the dealer all was good. When I went to back into my driveway a picture of the Chevy dealer parking lot came up. Then lines came across the screen. Put in in park and tried again. The Chevy parking lot came up again then my driveway. The assist lines were missing and it appears to have water at the bottom of the screen. Now it's like a permanent image out of focus.
