I've installed a Backup Camera.
Bought the wireless unit from Costco for $100 Can.
Modified it to my preference.
Decided that since I naturally turn my head to the right before backing up, it was logical to have verification in the viewer at the same time. And I didn't want to obstruct my forward view, or distract from out stylish interior.
The camera is mounted to the lower side of the license plate so as to not interfere with the trunk latch opener.
I rewired inside the LCD viewer because I object to any excess visible wires.
Normally wiring is into the backup lights. I decided that since the viewer is not visible in the rearview mirror, I would have it on always, and use it as an assist for changing lanes. I wired into the side marker lamp. Mine go on with starting the car.
I'm very pleased.
I'll answer any questions.
