I just had to pull my Jensen over the weekend and your right, what a bundle of wires. Easy to disconnect but told the RV place that they are going to have to reinstall. Darn thing just quit. The only way to turn it off and on was with the remote but nothing else worked with the buttons. Could play a DVD through the TV using the remote and that was it. Have a few other items for them to fix when they come out to install the Jensen.
