Like RNajarian I have gone with FitCamX. It works well and has a variety of power hook ups depending on you model car. I initially went with the adapter to my mirror, but later on bought the separately fused cable to the fuse block. It was not to hard to route the cable past the A pillar air bag. While I have the rear camera I have not yet installed it. I will get to that soon. They also have a couple of universal mount ones that also mount nicely if you don't have a console around the mirror.
