Review: Exactly what I wanted. Works perfectly. - It was incredibly easy to install -- took me about an hour, and most of that time was spent testing the car's wiring harness to find constant-12V, switched-12V, and ground wires to tap into. (Get yourself a good Digital Volt-Ohm Meter if you don't already have one!) It does exactly what I wanted it to do -- no compass or temperature display, which I didn't want since I already have both of those built-in to my car. But it DOES have the Homelink buttons so I don't have to carry around a separate garage-door opener anymore (yay!). The Homelink setup-instructions are pretty clear, too -- you'll need your current garage-door opener, and depending on the type of garage-door opener you have, you might need a ladder to climb up and press a "train" button on the garage-door motor itself. (Having a second person help you with this is not a bad idea -- he/she can press the "train" button while you're in the car operating the Homelink button you're programming. Took me all of 2 minutes to train the Homelink buttons to work with my garage door with the help of my girlfriend. Just make sure you're parked in a place where the door(s) won't come down on your car accidentally while you're training the Homelink button(s). And, supposedly, if you have the right system, you can train one of your unused Homelink buttons (there are three of them) to turn on-and-off lights inside the house! (My system doesn't do this, so I can't verify that personally.) The auto-dimming feature works *wonderfully*. No more having to flip my mirror manually -- this thing auto-adjusts the dimming depending on how bright the lights are behind you (goes from a little dimming to a LOT of dimming as the person gets closer to you), and it does so quite quickly so there's never a problem with glare ever. I highly recommend buying this mirror if you want an auto-dimming mirror that has the Homelink buttons on it, but you don't want the temperature or compass displayed in the upper-right corner of the mirror. Review: Plug type differs. Hard to see from the photograph in the description - Plug type differs from 2005 Prius. This mirror has two teeth and one row of pins. 2005 Prius has one detent and two rows of pin sockets. ## Features - Complete kit includes mirror, and wire harness ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B002Z600DY | | Auto Part Position | Rear | | Best Sellers Rank | #2,049,855 in Automotive ( See Top 100 in Automotive ) #3,851 in Automotive Interior Mirrors | | Brand | Gentex | | Brand Name | Gentex | | Color | Black | | Compatible with Vehicle Type | Car | | Customer Reviews | 4.0 out of 5 stars 57 Reviews | | Fit Type | Universal Fit | | Item Dimensions | 14 x 8 x 3 inches | | Item Weight | 1.75 Pounds | | Item dimensions L x W x H | 14 x 8 x 3 inches | | Lens Curvature Description | Convex | | Manufacturer | Gentex | | Manufacturer Part Number | GENK40A | | Material | Glass | | Material Type | Glass | | Mounting Type | Windshield Mount | | Operation Mode | Manual | | Other Special Features of the Product | Auto-Dimming, HomeLink | | Shape | Rectangular | | Size | 8 inches (W) x 14 inches (L) x 3 inches (H) | | UPC | 826003000027 | | Unit Count | 1.0 Count | | Vehicle Service Type | Car | ## Product Details - **Auto Part Position:** Rear - **Item dimensions L x W x H:** 14 x 8 x 3 inches - **Material:** Glass - **Brand:** Gentex - **Vehicle Service Type:** Car - **Mounting Type:** Windshield Mount - **Item Weight:** 1.75 Pounds - **Fit Type:** Universal Fit - **Size:** 8 inches (W) x 14 inches (L) x 3 inches (H) - **Shape:** Rectangular ## Images ![GENTEX GENK40A Auto Dimming Rear View Mirror - Image 1](https://m.media-amazon.com/images/I/71uf+WyzH2L.jpg) ## Questions & Answers **Q: Will it fit a 2015 Honda Civic?

Hard to see from the photograph in the description *by B***N on January 30, 2026* Plug type differs from 2005 Prius. This mirror has two teeth and one row of pins. 2005 Prius has one detent and two rows of pin sockets. ### ⭐⭐⭐⭐⭐ OEM quality mirror *by C***A on August 22, 2014* This rear view mirror with auto dim and homelink is essentially identical to OEM mirrors in high quality cars. I think Gentex provides mirrors to the automakers as it looks identical to the one in my Subaru. Works great, simple to install and program. I took it to a stereo shop to run the wiring because i was unsure about messing with the headliner in a brand new nissan. Highly recommended if you want one. ## Frequently Bought Together - GENTEX GENK40A Auto Dimming Rear View Mirror - Dorman 76864 Rear View Mirror Bracket Assortment, 3 Pack Universal Fit - Master Tailgaters Rear View Mirror Three Metal Bracket Adapters for Volkswagen, Audi, Dodge, Ford, Honda --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/14010314-gentex-genk40a-auto-dimming-rear-view-mirror](https://www.desertcart.pl/products/14010314-gentex-genk40a-auto-dimming-rear-view-mirror) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-28*
