Best $40 I ever spent. We all know rear view in our car sucks. I have the Bose system so I didn't want to disturb the stock look in the cabin. Even though I would love a touch screen it would never look as clean as the stock system. So backup camera was out of the question. Thanks to this sensor I didn't have to drill any wholes in my bumper or change the head unit. I used the backup camera install DIY on here to get an idea of how to hook it up. Finding the tail light wire in the back was the hardest part since I didn't have a meter to test the power but once I located it (found a simple way to do it BTW) the instill was easy and clean. Now I can back up into parking spots and not worry about hitting those stupid cement blocks. I highly recommend this thing.
