[Stl-986]

You need to remove the bumper to do this. It only takes 10-20 minutes to remove it. Going through the tail light is going to cause a water leak, I wouldn't go that route. Done this on a few 986 & many other cars. It really is not difficult.

You also have to wire the HU to a reverse wire so it can detect it plus the rca cable from the camera to the HU. Any competent audio shop can do this but dont let them drill through any metal, there are holes in the car you can use already. All in a a complete HU, speaker & rear camera install shouldnt take more then a day if you take your time.
