This is the NEW Gentex 3.3″ RCD Video Mirror. The 3.3″ display is the clearest and brightest yet. The 16:9 wide view gives a precise image of what is behind your vehicle. When paired with a backup camera the display shows a real-time panoramic view of the rear of the vehicle. The display appears through the mirror glass automatically when the vehicle is shifted into “reverse” it disappears when the vehicle is shifted into any other gear. This mirror comes with the standard 6′ wiring harness for a normal installation. If you have a pickup or RV or need a longer wiring harness we have the GENK332L available that comes with the 28′ wiring harness. Safety and Convenience* – From a safety perspective, the Rear Camera Display Mirror should help reduce the risk of backup accidents, especially for vehicles with limited rear vision. Another benefit is the convenience associated with hooking up to boats, RVs and utility trailers. Other Benefits – For car dealers, the Gentex video display technology is quick-to-market, easy to install and service, relatively low cost, and offers a seamless enhancement to the auto-dimming rearview mirror. *Please note that the video display mirror is intended to be used as a supplemental device for drivers and does not eliminate the need to check rearview mirrors or walk around the vehicle, should conditions warrant. When it comes to backing up safely, nothing beats walking around the vehicle prior to moving it. THIS ITEM IS THE VIDEO MIRROR ONLY. IT DOES NOT INCLUDE A CAMERA. WE HAVE THOSE AVAILABLE SEPARATELY.
