I have a 2007 Jeep Patriot with a Pioneer AVIC-F700BT radio unit. I was thinking about possibly installing a back up camera. I had the radio professionally installed, but if I do this, I would like to try and do it by myself. I have a few questions. First, how do I get the unit out of the car so I can see behind it? Secondly, how would I run the wires from the back of the radio all the way to the back of the car?
