Product Research

Features

Overview: The Gentex GENFDM3LN rear-view mirror is designed to replace the factory rear-view mirror and provide a continual image of what's behind the vehicle, via a rear-mounted camera, along with providing standard rearview mirror operation. Other features include automatic brightness control and the ability to add an optional backup camera (not included). The GENFDM3LN uses the factory mounting base and is compatible with most vehicle's mirror mounts.

Rear-View Camera: The Gentex rear-view mirror kit includes a 1.7 mega-pixel rear-view camera that can provide a continual display of the area behind the vehicle with no obstructions from headrests, passengers, luggage, etc. The camera features a high-dynamic range imager, with pixel-level intelligence, and FPGA video processing for crystal clear images. It's designed to mount on the interior of the rear window and includes 3 different angled brackets to accommodate various rear window angles.

  • 17˚ - 29˚: Typically used for sports cars and sedans.
  • 30˚ - 54˚: Fits most CUVs (Crossover Utility Vehicles).
  • 55˚ - 90˚: Designed for SUVs and Trucks.

Note: The rear-view camera is not designed to be used as a "reverse" or "backup" camera, and will not trigger when the vehicle is put into reverse.

Full Mirror Display: Along with fully functional, wide-angle, rear-view mirror operation, the Gentex features a built-in 9.6" LCD screen that uses almost the entire mirror surface for displaying a rear camera image, with 1600 x 320 resolution. A toggle button on the bottom of the mirror lets you quickly switch between Mirror Mode and Display mode, which uses the rear-view camera. Menu and Selection buttons let you adjust the display brightness, color level with red and blue adjustments, and an option for shifting the camera image up/down. The GENFDM3LN mirror features two modes of operation:

  • Mirror Mode: The mirror acts as a standard rear-view mirror, providing a wide viewing angle behind the vehicle.
    •  Auto-Dimming: While in Mirror Mode, the Gentex will detect headlight glare from trailing vehicles and automatically darken, helping preserve driver vision.
  • Display Mode: In this mode, the mirror will display the rear-view camera image, providing optimal rear vision without obstruction from headrests, C & D pillars, passengers, luggage, etc.

Optional Backup Camera: An optional GENCAMHAR harness (sold separately) is available for the Gentex mirror, allowing you to connect a backup camera (sold separately). The harness takes the place of the provided power/ground harness and includes a female composite video input along with a reverse trigger wire. When the vehicle is put into reverse, the split-screen image will be displayed, showing both the reverse-camera image along with the rear-view cam or mirror image.

Q
Will this work on Mercedes Winnebago view 2020 rv replacement rear view mirror?
angela  Jun 28, 2025
1 answer
A
The Gentex GENFDM3LN uses a standard factory mounting base found on most passenger vehicles and is not compatible with most Mercedes/Winnebago RVs, Angela.
bo  Jun 28, 2025 (Staff)
Q
Is it possible to remove the mount from the mirror, and replace with a Honda mirror adaptor to work with a 2025 CRV?
richard  May 28, 2025
1 answer
A
The Gentex GENFDM3LN does not have a removable mounting arm, Richard. The GENFDM3LN does use a universal style mirror mount button attached to the windshield and could be installed on vehicles that have different mirror mounting styles using an adapter (sold separately, not available from Crutchfield at this time).
bo  May 28, 2025 (Staff)
Q
Will this for a 2024 Ford Edge St?
phil  Mar 24, 2025
1 answer
A
We have not tested this in various vehicles. However, any vehicle with a windshield that is angled 17-90 degrees is expected to be compatible with this rear view mirror system thanks to the mount adapters that are included with it
jason  Mar 25, 2025 (Staff)
Q
Would this mirror fit a 2021 Mazda CX-9?
connor  Sep 28, 2024
1 answer
A
Greetings Connor. Thank you for your question. This Gentex mirror mounts to the windshield the say way the factory mirror does on your CX-9. There will be some wiring involved however.
thomas  Sep 28, 2024 (Staff)

Does this have a built-in dashcam?

Q
the second bed option that you can add can be activated at any time by means of a specific button or it only has the option of activating it in reverse?
alexcar  Jul 07, 2023
1 answer
A
I think you are asking about a backup camera that can be added when the GENCAMHAR harness is installed with this product. That backup camera will only be displayed when the reverse trigger wire is activated by the shifting into reverse.
jason  Jul 08, 2023 (Staff)
Q
Does this fit on a 2022 Toyota Highlander. And is there a digital mirror with homelink?
william  Oct 30, 2022
1 answer
A
That rear view mirror is not vehicle specific and designed to fit any standard rear view mirror. That particular model does not have Homelink however the Gentex ADVGENFLCHLN does have Homelink compatibility which I will link down below. https://www.crutchfield.com/p_220GFLCHLN/Gentex-ADVGENFLCHLN.html?tp=66448
arielle  Oct 31, 2022 (Staff)
Q
Do you have the one with Homelink also what kind of addeptor i will need for 2023 palisade?
mrugesh  Oct 28, 2022
1 answer
A
The Gentex ADVGENFLCHLN offers Homelike capability. However, we do not have an adapter for replacing the rear-view mirror in the 2023 Palisade.

Q
What kind of mirror adapter do I need to install this on my 1986 Toyota Land Cruiser?
ernest  Sep 14, 2022
1 answer
A
Unfortunately we do not have an adapter to go to your factory mount. It may be necessary to select a different mirror or install a D-shaped mirror mount as seen in most newer vehicles. For further assistance, please give us a call at 1-800-324-9695.

Q
Will the reverse camera work as a backup camera or do I need a backup camera?
joe towers  Jul 13, 2021
1 answer
A
The reverse camera does help give a better view from the rear of the vehicle and can be used as a backup aid. It is also possible to use an optional backup camera that has a composite video connection with this system in addition to the included camera

jahangheer  Jun 02, 2021

Yes, and quite well given it doesn't have an IR camera, but there will be a little bit of granularity in the pixels.
gregory  Sep 17, 2021

It claims it does, at this time I have not installed it, my appointment is two weeks out

Q
is this compatible with a 2010 dodge ram 1500 ?
john d.  May 20, 2021
2 answers
A
It installs using standard vampire taps to the original harness or in the A pillar. That said, I installed in a Dodge by checking the pin outs on the MOPAR connector repair site and just pulled the original pins from the MOPAR harness and inserted them in to this mirror's to avoid the bulk of tucking the original harness under the headliner, and not cutting or tapping the factory harness while I was unsure if I'd be happy with the mirror. A wasted effort in that regard since it's been a year of use and we love it
gregory  Sep 17, 2021
A
It came with a wiring harness. I installed it in a 2021 Nissan Armada and it works great. It should work with any vehicle.
jeffrey r  May 20, 2021
Q
Will this fit a 2020 c8 corvette?
steve  Jan 02, 2021
1 answer
A
We have not tested this in a vehicle but do expect it will work as it does work in sport cars with a windshield angle between 17° - 29° using one of the mounts that comes in the box
jason  Jan 20, 2021 (Staff)

Q
What is the screen resolution and brightness? I bought the previous version but its camera/display resolution was so poor that I returned it. Im assuming they have improved it but would like to know the specs before ordering.

Q
I am thinking of using this mirror in a mid engine car with a removable roof section, the rear window will still be in place. Will the sunlight glare be a problem seeing the screen?
mark  Jun 07, 2020
1 answer
A
Direct sunlight is always somewhat problematic but this Gentex mirror offers both automatic and manual brightness and dimming features. It should be able to compensate for the sunlight.
casey  Jun 24, 2020 (Staff)
Q
What makes this rear view mirror camera twice, or more, valuable/expensive than any other similar product?
carl  Apr 11, 2020
1 answer
A
Hi Carl, thank you for your question. The Gentex GENFDM3LN rear-view mirror not only serves as a rear-view mirror that utilizes a rear view camera that can show what is behind the vehicle at all times, it also serves as a standard rear-view mirror by using the toggle switch to move back and forth between image quality and usage type. The Gentex GENFDM3LN, is also fully compatible with an optional backup camera. Please chat with an Advisor online or by phone at 1-800-324-9695 if you would like to obtain more information, or compare additional products.
