Anyone install a rear backup camera? If so, where and how did you mount the camera. I'm a little hesitant about drilling into the rear bumper.

I just ordered the following from mobilevideoforless.com:

NAV-V300NS - Nissan Series OEM NAV™ Factory Navigation Video Input Module

RVC3000 - Low Profile Flush Mount Color Keyhole Reversed Image Backup Camera

 

I plan on installing mine in the center of the license plate. I've seen this done by other members and it's very discrete.

I like the camera! But isn't it a little expensive? Add the $15 RCA adapter + tax... ouch!

What other reverse camera's compare to this? Even at this price range. I'm just curious as to which cameras offer the best bang for buck.
