Something kinda new to me. This may be old news to some. I have seen some as low as 50 on ebay. Some come with a lcd screen that shows your revers when you back up and shows a picture of the person on the mirror and number when you are getting a call. Or like this one which is a little more basic but allows you to download your music to your mirror and play it back through your radio which is kinda neat. Especially if you dont have a ipod or have a aux port. And since this mirror is cheaper than a ipod and more convinient it makes it a sensible choice.

Eh personally id rather have integration to the speakers with a parrot device or something along those lines. Picture contacts on the rear view sound cool and all but not really necessary and sounds like too much of a distraction haha. But for 50 bucks why not give it a shot.
