My JVX, mounted on the front windscreen, causes a quite a bit of interferance to my radio (we only ever use FM) and the aerial is a wire style antena on the roof at the rear. It's not so bad that I can't live with how it is, but, it is annoying at times when my car can't pick up a station clearly where normally it would. My previous camera, a Blacksys CF-100 2CH + GPS, caused zero interferance. I don't see why I should have to mod my car or anything else to fix a problem that the camera is causing.
