Gentex 50-GENK2AM Auto-Dimming Rear View Mirror by Gentex

Not a difficult install once you find an ACC connection. Mirror works as intended.

First off, the actual product. I'm a hard critic when it comes to aftermarket products. I want the best for the return. Not cheap, but 'what you pay is what you get'. This is worth the $$. Found myself playing around while driving enjoying the difference and how much it helps. I live in Brooklyn and driving the BQE every night, its gets exhausting flipping my mirror to see traffic and then flipping again to tone it down.Installation. Okay for me, it was a process. I own a 2000 Honda CRV, so the OEM mirror mount is in the roof, not the windshieldMount: I had to mount a new metal bracket on the glass to hold the mirror. First off, buy the 3 pack of metal mounts. DO NOT USE plastic. It's not easy to mount to glass. I ended up making my own (work in a fabrication shop) to save time waiting for the mount. In terms of glue, stay away from epoxys, caulk, 5-minute adhesives, yada yada yada! It all takes time to cure only to find out it might not hold. You want UV Glue! It dries fast, and holds strong! I work with NYC Museums, Calvin Klein Fashion Exhibits, so trust me. If it holds for them, it'll hold for you!This stuff is great; https://www.amazon.com/CRL-UV702-High-Viscosity-Adhesive/dp/B006JFKP3W. It has a shelf life of 18 months after production. It's toxic, so wear a respirator. Don't forget the UV Light source, amazon has a bunch of flashlights, again need glasses, or just don't stare directly at it. Mark your window from the outside where you want the mount. Wipe the inside window and your mount down with any kind of stripper like acetone, denatured, rubbing alcohol. Apply a thin amount of UV Glue to your mount. Press it against the window. Tape it into place. Look outside and make sure the glue covered the whole area between the window and mount. Put the light source right on outside and shine down on your glue for a minimum 5 minutes, at most 10 minutes. Once hardened, its not going anywhere!Wiring: Okay this was a bit of a challenge, I could tap into my radio, but it's a headache getting it out. The easiest thing to tap into for me was the window adjustment control. It normally just pops out! Disconnect the harness and feed that down to below your steering wheel. You'll need a multimeter, wire strippers (at least 20 gauge) , crimps and crimpers. Don't use the splice connects they give you. Not safe and will fail eventually. Could buy this set, https://www.amazon.com/EL-SKY-Terminal-Connectors-Assorted-Electrical/dp/B01LA82M8S. It'll last you awhile. Use the red butt crimps. Check the wires until you find a 12v source. Should only be one. Clip, strip, crimp, plug it back again. Done.

While the mirror doesn’t come with instructions, I bought a fuse tap and crumpets too.This is how I installed it for a Chevrolet Sonic:1. Purchase a fuse tap, electrical tape, and crimps.2. Connect the fuse tap to the red wire and crimp it. I had to remove the head of the red wire in order to crimp it to the fuse tap.3. Open the fuse box which is to your lower left below the steering wheel.4. I added the fuse tap and ran the wire out of the fuse box below the port and inserted it into the weather stripping all the way up to the rear view mirror.5. The fuse tap was inserted into the onstar fuse opening since I already had installed a CarPlay radio and removed all the onstar functionality from the car.6. The mirror worked great and turns on normally. Great for driving at night.

The mirror fit well in a 2023 GMC Sierra 1500. GENTEX is supped to be an OEM supplier, so this mirror looks OEM.Install of the mirror itself was pretty straight forward. You remove the forward camera surround and unscrew the old mirror, then slide this new mirror in and tighten the screw. The hard part, at least for the Sierra, was finding a switched power source. The USB fuse is switched, but it's a triple fuse and I didn't have a tap for that. So ended up running a wire from the 12V outlet, routing behind the glovebox and ending in the passenger fuse area.

I installed it on my 2023 Nissan Sentra and it fit plus works perfectly. When I got the car it came with a manual mirror. The dimming is quick and just works! It's one of the best upgrades you can do to your car if you have a manual mirror with a reasonable price!

To understand why a low review please read on. This is the second of these mirrors I have bought in the last few months. The 1st one was perfect. This one came in a very badly damaged box, maybe water damage, Wiring loom loose, no instruction card. Gentex Customer service had a test sequence but I could not tell if the unit worked on the bench when 12v was applied. I wrote to Gentex customer service and they took two days to get back to me. They recommended that I return the item through Amazon as they feared water damage. However while waiting for this response I installed the mirror in my new Subaru. Worked perfectly!

The mirror is OEM quality, so it os very good. It functions to OEM quality as well. Installation is easy if able to connect to a 12V power source. I attached it with proper installation materials to the overhead lighting section which powers off about 10 minutes after locking the vehicle. So that worked pretty well. I did use the little cable channel to hide the wiring. What I don't like is that this mirror after a year of use is now a little loose around the ball joint. It would be difficult to find anything better than Genxtex however. The rattle does not create a noise and in most road conditions does not negatively affect its function. Most people might not even notice except when you move the mirror for adjustment.

These mirrors work as well as the OEM mirrors that come with many car models.
