Yes mine works flawlessly. I had said I was going to ask for you already. So here is some information he gave me on mine. He is not an expert btw so take everything with a grain of salt (but he's helped me install other equipment in the car before, so I trust him).
He wired mine to switches to operate the on/off functionality for movies/camera views. As far as the reverse, he didn't do that for mine since I had no camera for reverse (don't need). However about this he said you might want to wire it to the power going to the reverse light?!
As for the parking brake sensor, as I said he ran it to a toggle switch w/ ground (and an additional one for the brake itself that had to be tapped 3 times to another toggle button). There were 2 wires he had to use... both were yellow BUT one had a blue stripe, and the other a black. Each were for 2 different things (one was brake, other was parking brake I guess). He doesn't remember which was which but for sure how to get to them is under the steering wheel column, theres a big panel (only one I see besides the little fuse box) and right under where the panel meets sterring wheel, give it a tug and the clips should snap off from the hooks and it should rotate down... I found that you can actually take it off completely if you need to by letting it hang all the way down then moving the sides of the panel toward the seat and then moving it downward at the same time.
Then after you get in there theres a cluster of wires... see which has the TWO yellow wires (one with black, one with blue stripe).
You could I guess hook it up to one and if it doesn't work then...
but atleast that is something to work with.
He doesn't know about the reverse wire on my car as far as color goes.
Hope this helps. [^]
