I used a cheapo $20 backup camera from ebay with infrared -- it's great. It is mounted just right of center, to the right of the license plate light. The hole for the wiring is directly behind it and is not visible from any angle. I'll try to grab a pic tomorrow.
I removed the whole license plate / reverse light assembly to get better access to everything. The head unit requires a +12v signal to switch camera views so I connected that wire and the camera's power wire to one of the reverse lights. Camera ground also shares the light harness.
I drilled a secondary hole into the trunk lid for the signal wires to pass through. It is 1/2 inch and a single RCA wire barely fits through. It's ok to drill this though because your trunk lid is a composite material that cannot rust. The wiring stays behind the trunk liner panel and it fits easily into the factory wire cover along the right trunk post.
The biggest PITA of the whole job is simply getting the retainer clips off that hold the trunk lid liner in place. After that it's easy going!
