Hi Group, I'm new on here. First time post. I just purchased a 2011 Ford F-150 with a backup camera. Well, it doesnt work. When I put it in reverse I get a blue screen for about 5 seconds on my rear view mirror then it goes blank. Just was wondering if anyone else has had the same issue and if so what did you have to do to correct it? If no one has had the same issue can anyone steer me in the right direction to start checking it out?
Thank you for any input anyone can give me and it's great to be able to be on here
