Description

Ordinary rear view mirrors are a pale reflection of this fully-loaded K31 Auto-Dimming Rear View Mirror.

The K31 Auto-Dimming Rear View Mirror detects dangerous rear-approaching light and eliminates it with "intelligent" circuitry. And, less glare means less eyestrain and driver fatigue. Plus, your night driving vision stays sharp.

In addition, the K31 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. As if that weren't enough, it's equipped with handy driver and passenger side map lights.

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 k31 Auto-Dimming Rear View Mirror comes with 3-year / 36, 000 mile warranty. See what a difference the Auto-Dimming Rear View Mirror can make.

Notes

  • Installation of the mirror's electronic components requires some hard wiring (see Installation Guide tab for details)
  • 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.

"Very disappointed that the wire cover was not included and is an option piece. This piece should accompany the K31 mirror for appearance, open wires showing is in exceptable for the price paid for this product."

"This mirror was put on my 1984 El Camino. What a great change from the original manual mirror. Compass auto-corrected well. Thermometer is accurate and resolution of mirror is very good even w/ photochromics. I added the driver and passenger light upgrade option which works fine, but a little boost on lumen power with LED's might make this mirror perfect."

"This is the mirror to get if you have a '98 Sebring LXi! It connects to the stock cable/plug no problem. You just have to run the temp probe if you want the temp, otherwise it's fantastic! MUCH less expensive than OEM replacement mirror ($535 to $585 for Chrysler replacement)"

"I may have assumed that this mirror would be a one for one installation. The PT cruiser I own is a dream cruiser, series four, convertible, "High Output Turbo", with an electronic mirror factory installed, but it doesn't have auto dimming. It will take some disassembly to install, but I an capable to perform the installation. One feature that will not work with this mirror is the Map lights when the doors are open. Why no wiring diagram??"

"First, installation was a breeze factory clip plugs right into the Gentex( only thing extra that needed connecting was temp....5 mins to install)I do alot of early....early morning driving to work. Before the gentex k31 i found myself constantly ajusting my mirror to stop the cars behind me from blinding me (because we all know those people that have their brights on and have no clue) now with the auto dimming, brights are not a problem anymore.....I NOW CAN DRIVE!

"This mirror looks and works great! It took a while to hook up but the instructions helped out quite a bit. Hooking up the powers is almost identical to hooking up a stereo system's power (same wires). The compass is very accurate and the map lights offer a pleasant yellow/green soft LED light which helps reduce the effects on your night vision (as opposed to the old standard white lights)."

Posted on 04/03/2007 by Ron T. (Farwell,MI)

"Read all the reviews and decided to buy this mirror, It took me a little longer than normal to install this into my 05 Colorado. I had to call the tech support on clarity of the wiring. They helped me out in a very short time period with excellent instructions. Once installed everyting worked great. As other people have stated the map lights are dimmer than the factory ones, but other than that everything is great."

"The K31 isn't listed as compatible with my 79 GMC. However, I went to my local Ace Hardware store to get a replacement set screw similar to the OEM mirror's, and it fits perfectly. The map lights are not terribly bright, but they are effective. Get the "optional" cable cover."

Awsome product - manual and support lacking

Posted on 02/12/2007 by Henry A. - 2006 Chrysler Sebring (Corona,CA)

"Found the mirror to be of excellent quality. Was wondering about the dome light function of the car, and if it would still work. This wire is on pin 6 in the factory harness. No mention of that function in the manual. I checked ignition, constant and ground wire locations - same as factory harness. Emailed vendor for advice on dome light. Since it was the weekend, got no response. So I went for it, and plugged the mirror into the factory harness. All functions including the dome light work perfectly. Plugged the temp sensor into the empty pins 4 and 5 of the factory harness. Got an answer from my email on Monday - saying the dome light was not supported, did not work, and to not use the factory harness.... Oh well. Glad I did not listen to their tech support. Great product. It was my wife's Valentines gift. She loves it.Also the vendor needs to update their model year support. Indicated the mirror worked on Sebrings up to 2004. It worked perfect on our 2006. They could also include a basic wiring diagram along with the printed instructions."
