The K21 Auto-Dimming Rear View Mirror detects dangerous rear-approaching light and eliminates it with "intelligent" circuitry. What's more, less glare means less eyestrain and driver fatigue.

As if that weren't enough, the K21 Auto-Dimming Rear View Mirror comes with a self-calibrating digital display compass. The mirror even has an exterior thermometer that displays temps and ice warnings.

The windshield-mounted mirror comes complete with detailed installation instructions and all necessary hardware - perfect for the experienced do-it-yourselfer or professional installer with some wiring required. And, the Auto-Dimming Rear View Mirror comes with 3-year / 36, 000 mile warranty. See what a difference the K21 Auto-Dimming Rear View Mirror can make.

Notes

  • The Gentex Wire Cover is highly recommended if there is 3" or more space between your mirror and the headliner. It conceals otherwise loose and visible wires running to the mirror. Select this part under "optional accessories" above.

"The Gentex 21 Rear-view mirron works really well and looks great. The mirror cost $200.00 dollars and it cost me another #100.00 for professional installation. Don't allow a do-it-yourselfer to install this mirror! I think the results where well worth the price. It works just as well as factory installed equipment. This mirror went into an '08 Honda Ridgeline."

"The installation of this mirror was very simple, with the exception of where to obtain the power source. Since most cars are very different, the instructions did not provide the necessary information to locate the 12 volt key activated connection. Once this was located, the information was a snap! The product is excellent"

"I recently purchased a Toyota Tacoma. One feature on my previous vehicle I liked that was not on the Tacoma was an outside temp indicator. The Gentex K21 was a great solution for the Tacoma. It was relatively easy to install. The instructions were not very clear as to the replacement of the temp probe. A call to customer support connected me with a pleasant and helpful tech who quickly answered my questions. Since I was most interested in the temp function. The auto dimming was not the primary capability for me in purchasing this unit. I have found the auto dimming function to be a real plus. I always like having a compass and this option works well. The temp reading has proven to be accurate. I am very pleased with every aspect of the mirror. This is a great product."

"The product is exactly what I expected when I purchased it. My only criticism is I wish the compass/temp gauge readout was a bit larger. The install was easy but a that owes to the car and that I looked up a "how-to" article on a car forum. The instructions that come with the mirror are only so-so."

"The installation was fairly easy after we found a 12V power source. In the Mustang the power source is located behind the kick panel on the passenger side. The mirror looks great and works perfectly."
