Major PITA to install as there are no instructions, it needs modifying or additional wiring and the wiring that was there form another backup camera kit needed some additional modifying. The camera itself seems decent and has a stock look to it.
The existing wiring that was there was aftermarket and was cut off in the drivers side pillar, it was likely used for a rear-view mirror backup camera with likely a license plate camera. I re-routed the wiring to the back of the head unit and spliced it into a pigtail connector I had lying around, also ran some more to extend the existing rear wiring to the upper tailgate as the harness that was there wasnt long enough.
Enabled it in the GAP tool and boom! I have a working backup camera.
Only slightly annoying part is that the camera is only turned on by the reverse lights, so when you through the car into drive, the backup screen stays on a bit longer with the camera being off - but I guess I shouldn't be too picky considering it cost under $20.
I'll post some pics shortly.
