I just put the Van-eyes piece in the back window - got it at Pep Boys for-----$1------ closeout bin!!! Man, what a difference! Camera? We don't need no stinkin' camera! Really - it works - and it goes on the inside (guess I'm stupid - I thought it went outside!), so if you have tinted windows, it's barely visible from the outside. I can see a straight pin on the ground 6" behind my car. OK maybe I'm exaggerating, but I can definately see a car RIGHT behind me, which is like seeing that straight pin compared to what I used to be able to see!!
