    Anyone know the function of it? TRD-OR with the auto sensing dimming. Located on drivers side, windshield facing side of the rear view mirror. Wondering if i can semi-cover it up with a dash cam install.

    I can't seem to find any information about this lens/sensor in the manual or in the forums here.

    It’s the ambient light sensor for the auto-dimming mirror.

    It is the light sensor, hold your finger over it and the mirror will change.

    Sure. But the auto dimming feature of the mirror won't work correctly.
