I tried a wireless system with the SUV I used to have, but the signal was poor and broke up too much. I was just trying to see the hitch, so I knew it would be useless to try behind a trailer. That's why I went to the wired system. My factory installed in-dash navigation system does not allow connection to an external video source (initially, I wish it did). I use my camera also as a rear view mirror, not just a backup camera. When I pass someone and I can see their entire front end in the camera, I know I am clear and can change lanes. For that reason, I prefer the monitor sitting on top of the instrument panel over looking down at the in-dash navigation screen.
