This is the Momento MR-1000 (R1) rear view mirror with a built-in 4.3" LCD screen. It has a 9 position adjustable guide line feature (for gauging distance when backing up). This mirror also has dual video (2) inputs.
The Momento R1 works exactly like backup cameras sold in newer vehicles - except instead of a separate screen, the R1 has a built-in LCD that is connected to cameras installed at the front and rear of your vehicle.
While you are driving normally, the Momento R1 screen remains off until you shift into reverse gear.
When you shift into reverse gear, the Momento R1 screen comes to life, showing you what is happening at the front and rear of your vehicle.
The Momento R1 also has parking lines to provide guidance when approaching a nearby object.
The R1 mirror has a hidden environment sensor that will automatically adjust the brightness of the LCD in different lighting.
In addition, if the R1 mirror is connected to a Momento C3 camera, the LEDs on the camera will adjust to the external lighting.
