Just trying to find what I am over-looking. Truck was having some issues so disconnected batteries and reset the CPU - truck is good now. But I lost most of my radio settings including the rear back up camera which was working perfectly. I decided to do a Reset on the unit. Now when I start the truck, the HU switches up to the rear camera and stays there until I hit the "x" to close it. But putting it in reverse now does not bring the camera back up like it would before. There has to be a setting that is missing or backwards but I am not having any luck figuring it out.
