We just had a trip to Mobile Alabama from Gettysburg South Dakota. Everything worked very well back up camera everything. Stopped at a rest area in Kansas and the back up camera doesn't work. Any suggestions?
Perhaps someone stole your camera while you were parked at the rest stop? :))
Just kidding.
There should be a removable panel in the cabinets above the head of the bed. Behind that panel you'll see the wiring for the camera. See if anything looks amiss. Check for good 12V at the camera power wire.
Like Chuck said, do your due diligence in trouble shooting the camera system.
Mine failed also and the audit system was failing.
I ended up just recently installing the below camera system. Viewer plugs into the aux power outlet (aka cigarette lighter) and includes suction mount. I mounted mine on the small window to the drivers left where I could glance at it with ease and still could see my mirrors.
Camera mounts on license plate or with 3M tape. Camera adjusts 70 degrees up and down and has a built in solar charger.
Works fine for me, do what suits you best.
No affiliation. Blah. Blah.
