We have been plagued with the center camera on our Weldex system and sometimes on the left or right camera. The problem was and is the connectors. I can disconnect and reconnect and they work fine for awhile. If it rains I can count on the rear camera flaking out until it has a chance to dry out from the increase humidity. My connectors are all located behind the radio and I rerouted them to the left of the console and hold them with a velcro strap to make it easier to work on. During the winter I'm going to replace the crappy wiring with good quality coax and connectors. I found a way to run coax to the back of the coach alongside the TV/SAT cable and will keep the existing cabling to carry the microphone and camera tilt signals. I looked at replacing the whold system but the Sony and Voyager use horrible cabling and connectors. Actually, the camera and monitor are really pretty decent quality. The cheap cabling and connectors introduce a lot of noise and bad connections.
