Anyone know which wires to tap into to run mirror and after market head unit at the same time. I have the factory backup cam. Want to get started on install when head unit arrives on thurs.

The reverse camera is great, with that said people over exaggerate about its necessity. I've driven other RWD coupes with poor rear visibility, simply use your left and right rear view mirrors and the dash mirror to gauge the distance between you and the car behind you. An experienced driver will have no issue, I've reversed countless times without having to turn my head. Granted always be cognizant if children are at or around your car prior to reversing.

I have the Ebay license plate light mount camera. It's a big help but I still rubberneck left and right when reversing, the big hips are a huge blind spot that no reverse camera can help with. I would LOVE to have a camera on each hip of the car and split the screen between left/center/right images, that would be sweet!
I routed mine into my Navi monitor. I'm glad I have it, did it all myself and it ended up costing about 225.00, the Black box for Navi 200+, and the camera about 25.00 or so.

i have one and when it decides to work it works great. i have a aftermarket headunit and a camera. so yeah, it is worth it.
