A:Answer No reason that you couldn't mount one. You will have to see if a license plate or bumper mount is the better option, but then it should display on your nav screen IF your head unit has an RCA video input. There were different radio/display options available, so it would depend on the model, but most have backup camera capability. If it does not have a camera input, you can buy an adapter that will add the necessary video input, but they can be pricey. In that case, it might be better to just replace the entire unit with one that offers radio, nav, audio, and video.
