I just bought a 2013 prius C package three. It comes with the toyota nav. monitor system. now I want to hook a rear view camera to it. I am going to get a professional to do that, but anyone has done this before through Toyota dealership and whether or not that would be the best way to do this? Or if there are any third party that does that such as best buy, etc. please let me know also. What kind of rear view camera would be best for prius C?
