lojeff- heh...if I hadn't been interrupted as much as I was, it would have gone faster...

: When I hooked it up, I had previously already run the wire from the head unit to the back of the 4r, so that part wasn't needed. I'd say, it prolly took me closer to 4 hours or so to do it all. so I'd say wait for the weekend unless you like a late night.
oh, and when you do it, make sure you keep some form of switch hooked up to the release for the back door. I removed my bezel and out of habit closed the door. unfortunately, the bezel was ni my hand disconnected...i.e. I couldn't open the door w/o crawling inside and hooking it up and opening the door again.

rando- honestly, in my quest to get a camera, I found that most of the regular cameras just weren't up to snuff when it came to low light ability AND hi brightness areas. I'd consider getting one of these cameras made for a rearview camera and then just interface it with one of those video -> usb input devices. that's prolly a more expensive route, but it'll prolly give you a better picture. dunno...ymmv.
I'll try to go back and take a few pictures of how I ran the cable and describe it better. I'll post an update when I've got that done.
