@Solfire The installation was really easy, I got power from the factory jack inside the upper console area, as has been described. I ran the wire to the rear along the upper trim. I
think it's not in the way of the air bags. I think most of the value in cameras is out the front, as if you are rear ended it is usually clearly their fault; however I really do like the rear cam. Another cheaper option is the VIOFO, a well-regarded 4K camera that can take an optional rear camera. I think the front/rear combo is something like $250, plus the wiring kit is extra, as is the circular polarizing filter which you get along with the u1000.
I've been sold on dash cams since I bought my first $60 cheapie-- the same week a lady missed her turn, stopped, put it in reverse, then backed right into me. THEN DROVE AWAY... I chased her down and she was full of attitude until I pointed out the dash cam. w/o a dash cam it would have been ugly trying to get her to pay. Knock on wood, nothing stupid has happened since.
I am going to wire the u1000 into my lithium battery system, so I can record for a long time while parked. that may prove to be interesting.
