Yesterday (yes, I am cheating), I had my BimmerTech rear backup camera installed professionally. I had to go to two different places and then get their most experienced installer who had installed the BimmerTech in one other car. It went fairly smoothly, but when it was all hooked up, he got no video whatsoever on the nav. screen, even for the radio. So he called BimmerTech (fortunately, they have a U.S. number even though they are a foreign company) and the owner of BimmerTech, Patryk, was able to quickly solve the issue and all is working just fine now. I really do love the rear camera and it is almost essential since I had the dark window tint installed. I highly recommend the BimmerTech camera, but it is a bit tricky if you are planning on installing it yourself.
