The camera/handle install is pretty easy, pulling the signal/power cable through the trunk boot at the base was a little tough but not too bad. There's a male/female connector junction just below the trunk opening so you can run the signal/power extension from there(under the trunk side panel, covers the wheel well) into the cabin. I ran my wire under the passenger rear seat and then down the passenger door molding, up and behind the glovebox and then into the console area behind the head unit where it plugs into.
Hardest part for me was finding space for all the jumper harnesses and power relay that have to fit behind the head unit. BMW does not leave any spare room in the dash like on other cars I've owned.
