Just fishing for ideas here since I am planning to install a backup camera with my avic-n1, I am wondering how everyone else ran their wire to the rear bumper.

 

There's a rather large hole right behind the license plate in the trunk with a groment already there. The license plate lights run though this hole. I just took a hobby knife and X'ed another hole in the gasket for the cables. Here's a picture looking aft towards the back of the car. That's fatmat acoustic dampener aross the back and bottom.



Here's the picture of my $37 e-bay camera.

 

oh cool, how is the camera btw?
