Anyone have experience with a rearview mirror backup camera set up?

Here is another picture.

I used a flexible speedometer cable in through the visor hole and down through the "A" pillar hole. I still had to shake it a little bit to get it all the way down.. I opened the hole in the kick panel to 3/4" and used a piece of wire with a small hook on it to fish the cable over to the kick panel hole. It still took some time to get it done.
