Tools required

Installation Instruction

Turn car off . Remove the negative battery cable and safely tuck cable out of the way
Remove the factory mirror from the windscreen. Most mirrors are removed by loosening the T20 Torx screw on the mirror base and sliding mirror upward towards the headliner. *Mirror removal process may vary by vehicle.
If needed, remove body panels for mirror and camera installation.

For example, the a-pillar may require removal as shown above.

Mount the Full Display Mirror on the windshield by sliding the mirror mount over the button. Tighten the T20 Torx set screw to 13.3 – 17.7 in-lbs.

*Specific vehicle adaptors may be needed. 5. Plug mirror power harness into the connector on the mirror.

Route the mirror power harness to a location where 12v ignition and ground lines are present. Secure the harness along the route with foam tape and wire ties.

Ignition and ground tap point are typically found in the A-pillar, Junction Block or Overhead compartment.

Find 12V switched ignition and attach t-tap using pliers. Repeat for ground supply. Ensure t-tap is snapped together.
Plug the mirror harness into t-tap’s as noted above. Ensure the spade is properly seated into t-tap.
Plug the longest piece of coax harness into the female coax connector coming from the mirror. Wrap a piece of foam tape around connectors to prevent rattle.
Route long piece of coax harness to camera mounting location. Secure coax harness along route with foam tape and/or cable ties.

If 90 degree connector cannot reach camera, another length of coax wire (purchased separately) can be used as an extension. The maximum recommended overall coax length is 30ft. It is also recommended to use cable ties every 150mm and within 30mm of a connector. Only use the 90 degree connector to plug into camera.

Plug shorter piece of coax harness into the long piece of coax harness. Wrap a piece of foam tape around connectors to prevent rattles. Ensure 90 degree connector can reach camera location. Secure harness along route with foam tape or cable ties.
Choose camera mounting location inside the vehicle. Measure the angle at location chosen. Most smart phones have a built in angle finder.

Tips!
Final mounting position of camera should be located as high as possible.
Final mounting position of camera should be in between defrost lines and in wiper path, if possible to ensure unobstructed view. Final mounting position of camera should be in center of vehicle.
Do not place camera on sliding or moving glass.
Camera should only be mounted inside of vehicle.

Choose appropriate window bracket for angle measured.

Examples:
17°-29° – Sports Cars/ Sedans
30°-54° – CUVs
55°-90° – SUVs/ Trucks

Clean both interior and exterior of glass of mounting location.

Ensure interior of glass is dry and debris free to ensure best foam adhesion during camera installation.

Install camera into window bracket (measured for vehicle).

Do NOT take off two way tape liner.

Screw in both T-10 camera set screws provided (one on each side).

Do NOT tighten.

Plug the 90-degree coax cable into the camera.

Only the 90-degree cable can be used to plug into the camera!

Reconnect the negative battery cable.
Toggle lever back towards rear of vehicle to place mirror in display mode.
Do NOT take off two way tape liner. Hold camera bracket with camera to mounting location to test location chosen. Dry fit camera in location.

Tips!
Ensure camera cover does not interfere with vehicle interior.
Ensure coax cable can reach and can be tucked out of the way.

Do NOT take off two-way tape. With vehicle ignition on and mirror in display mode, aim the camera. Choose location that image looks best in mirror display.

Tips!
Ensure camera image is level.
Ensure camera can point at horizon.

Using masking tape, mark the location at which you would like to mount the camera.
Double check the mounting location is correct. Remove two-way tape liner. Ensure debris or hand oils do not get on two-way tape.
Caution!
Adhesive is diffi cult to remove. If done incorrectly, a new bracket and adhesive is recommended.
In mounting location, place window bracket onto rear glass. Press, hold, and apply even pressure across the entire surface. Press and hold for 1 minute. Install temp should be above 50 degrees Fahrenheit.
Adjust camera up or down on the window bracket so the image (in display mode) has the horizon in the upper third of the mirror.

Tighten both set screws on camera mounting bracket. Do not over tighten.

Install camera cover. Secure camera cover with the two T-15 screws provided. Do not over tighten.
Adjust camera image using mirror settings. Adjust the tilt up or down so the image is centered. The image may still appear rotated, however the product is equiped with an auto rotate feature. You will notice the screen shift periodically for the fi rst 30-60 minutes of driving. After that time the image will be level. Please refer to quick reference guide for full menu instructions.
Install the wire cover over the two harnesses by seating the bottom of the cover into the mirror mount and then sliding the top of the cover up to the headliner.
Place paper product (quick reference guide) in the glove box.
If you would like to add a secondary camera via NTSC input you will need to activate the mirror’s secondary camera display. To do this, fl ip the toggle switch to mirror mode. Then, hold the farthest button to the right for 23-27 seconds. An image will display indicating the RCD display is now active. This secondary NTSC input is triggered by 12v to pin 8.
Testing Auto-dimming Function.

To test dimming function, toggle lever forward towards windshield to place in mirror mode.
While in mirror mode, using a dark cloth or cardboard, completely cover forward-looking sensor. Mirror will dim after a few seconds (depending on light conditions).

Troubleshooting

Mirror shows the video display and reflection of vehicle interior. Mirror has excessive glare in display mode.

Switch mirror back into mirror mode by pushing toggle switch forward. Then readjust mirror head so that driver has a clear rearward view. When placed back into display mode, the mirror head will be tilted upward, removing the interior reflection.

Mirror display is hazy, gray, or foggy.

Check rear glass to ensure it is clean.
During certain weather conditions the rear vehicle glass can become foggy with condensation. Switch to mirror mode until camera view is clear again. Turning on the rear defroster will usually solve this issue.

Mirror display appears obstructed or out of focus.

Switch to mirror mode until it is safe to examine the camera and rear of vehicle for obstructions, dirt, water droplets, etc.

Mirror display appears grainy at nighttime.

In order to display the best possible image, the camera will automatically adjust its frame rate during dark conditions. A lower frame rate can make the display appear grainy. The camera is still operating as intended.

Congratulations and thank you for purchasing a Gentex brand Full Display Mirror (FDM®). This intelligent rear vision kit consists of a unique display- integrated mirror and custom-designed camera engineered specifically for automotive rear vision.

The FDM offers bimodal functionality. In mirror mode, it functions as a standard auto-dimming rearview mirror. But with the flip of the toggle switch, the mirror enters display mode, and a clear, bright, LCD display appears through the mirror’s reflective surface, providing a wide, unobstructed rearward view. While in mirror mode during nighttime driving, the FDM also automatically detects glare from trailing vehicle headlights and darkens to the precise level necessary to eliminate the glare and preserve driver vision.
