Back up safely using this Garmin BC 30 010-12242-10 wireless camera, which transmits footage to your GPS receiver from up to 45' away. A frame rate of up to 28 fps ensures smooth video (actual rate depends on GPS, not included).
This is a great option if you already have a compatible garmin GPS to add-on to your car as a rearview backup camera. Good resolution and clarity both during day and night. Best buy did a good job at installing as well.
