THANK YOU Steve for your 2019 post! My husband and I are having the same OP issue in our rig (2005 Monaco Camelot 40PD). It has been very difficult to get answers, especially because no one has seemed to have truly resolved the problem. He's tried ALL of the above with no success, except for really, really digging into the backup camera wires and cables. He hasn't given up yet, so back to the backup camera we go. We'll post how it goes. Susan
