This mirror provides the OEM look while providing features your OEM mirror doesn't have. Gentex is the OEM supplier of mirrors to many automobile manufacturers and they hold the auto-dimming patent. Why not buy your mirror from the best?

The auto-dimming feature allows your mirror to dim itself automatically when it senses headlight glare. This makes driving at night safer and more comfortable. This feature is only found in mirrors from Gentex and Magna. Gentex is also the official supplier of auto-makers who use auto-dim mirrors, since they hold the auto-dimming patent.

The built in 3.5 inch TFT LCD display screen gives a precise image of what is behind your vehicle when used with a backup camera. The display shows a real-time view of the rear of the vehicle. The display screen is hidden. Once connected to a reverse wire in the vehicle, the display appears through the mirror glass automatically when the vehicle is shifted into "reverse" and it disappears when the vehicle is shifted into any other gear, leaving the appearance of a standard mirror. (So you don't lose the use of half your mirror.)

This rear camera display mirror should help reduce the risk of backup accidents, especially for vehicles with limited rear vision. It is also convenient for hooking up to boats, RVs and trailers. *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.

This has OnStar functionality built in and it is a plug and play replacement for your existing factory mirror. (It is not for adding OnStar to a vehicle that doesn't have it now.) You don't lose any functionality with this mirror but you gain auto-dimming and a built-in LCD monitor! Compatibility with OnStar is for most 2005 and newer models with digital OnStar. **However, it will not work on 2008 Cadillac STS & DTS, or on any GM vehicle with a Passenger Air Bag Indicator Light built-in the mirror. It also may not work on the following models: 2008 Chevy Trailblazer, 2010 Buick Lacrosse, Cadillac SRX, Camaro, Saab 9-4x, Chevy Equinox, GMX Terrain, Cadillac CTS coupe & wagon.**

Professional installation is recommended, as connection of reverse, power and ground wires may be required, as well as routing for said wires.

*Gentex has a MAP policy. (Minimum Advertised Price.) We advertise at the Gentex minimum. If you find someone advertising this product for less, please be aware you will not have a valid Gentex warranty or get free tech support because proof of purchase is required for those processes. Is saving a few bucks worth that risk? If you have questions about MAP please call us at 877-479-1633 or use the Contact Us link to email.
