How about a dashcam with a forward and rear camera? Get one with a screen and you can see the rear camera. It's not integrated and the screen isn't real big on most of them, but it has the double feature of recording if you want to record your drive or keep a video record in case someone wrecks into you, and you can use it to record stupid drivers as well or see what the dealership is doing with your car. I saw a video where a guy took his car to the dealership for a yellowing clear bra. The tech got in the car and called him a ******* idiot and drove it into the back lot. About an hour later they drove it back out to him. Never even looked at the car...
I'm looking into a dashcam for my car and this one looks pretty decent with a small footprint.

As I said, the screen is smaller and it's not integrated to the car, but it's also a lot cheaper option.
