Finished wiring up the rear camera and the GPS unit...camera seems to work really well, both in low light and high light views, also gives a wide enough view that when driving down the road I can still see the car off to the side as it comes into view from the drivers seat, this means much less blind spots. The screen is attached to a custom above sun isn't console that I will try to get some pics of shortly..
When not using the GPS it is on a ram mount so it sits up close to the console and out of the way....less for prying eyes to see also..
