All you have to do is when you are watching the movie watch for the part where Vince is looking through the glove compartment for a tape. It will show a frontward shot of him where you can clearly see the back window. Now most of the time you are watching him to see what he is doing but look at the back window and you can clearly see the camera mounted on the top of the window. My husband said that it was a brake light but you can see the brake light on the bottom of the window. The shot goes from back to front quite a few times so just make sure to be looking for it.
