Install completed!
It took me the better part of 2 days, but I got it done. The unit isn't quite flush, it sticks out about 1/4" at the bottom, but it looks ok.
No major problems, everyting went smoothly. I ended up installing both the mic and the camera for the unit, Voice activation and bluetooth work. I now have 2 backup cameras. One shows on the unit and the factory shows on the mirror.
The hardest part was running the wire for the camera. I'm very picky and didn't want the wire to show. Ended up removing the panel on the lift gate and running the wire through the rubber grommet that connects the liftgate to the body.
Programming the PAC SWI- was a pain. I must have redone it about 20 time before I got it right. I may still go back and make some adjustments later.
Now I just have to learn how to use it!
