My car is a 2012 Toyota Prius C and does not have a built in rear view camera. The Garmin BC 40 fills this gap. When parking in busy parking lots or in old neighborhoods with small or dead ends, having such a good backup camera helps me avoid fender buckling and unthinkable injuries from an unexpected pedestrian walking behind my SUV. This camera connects to your vehicle via Bluetooth. compatible Garmin vehicle GPS device. Visit the Garmin website for a list of compatible devices. The connection was easy. I was concerned about installing it on my Toyota. My concern was in vain. I removed the rear license plate holder, placed the metal template that came with the backup camera over the license plate and securely attached the camera. The alignment was perfect and the camera view more than adequate. I haven't experienced any issues with car washes, inclement weather or theft. The camera harmonises. I'm so glad I bought them.
