VR3 Wireless Back up camera.
I am posting here rather than in problem solving because I bought one of these useless things without reading about the problems others having.
I live in the boonies with no cell phone towers or have a heavy duty PU with a lot of metal in it or any other things that could possibly cause interference in this unit. The preceeding items were used as excues by the manufacturer when they replied to Dale.
The picture is OK other than vertical lines running up and down the screen. I didn't even have the truck running when I tested it so engine interference was not an issue.
The VR3 wireless back up camera is a worthless investment and a waste of your time.
It's back to Costco for a refund.
