Unfortunatly, I have been troubleshooting this install and have not gotten anywhere yet. I probably have a defective screen. It is wierd that it does not turn on everytime I power it. When powered first, it shows image. Unplug and plug back on and no image. Unplug, wait about 10 seconds, plug back and I get image. This means that if I am backing up and then have to move forward to then back up again, I have no video image the second time I set to reverse. That sucks! or I wait about 10 seconds before I switch to reverse so I can see an image...lol I will probably try another screen.
