retaining the mirror by use of a mirror holder;
rotating the mirror holder to a position where an activation feature of the mirror holder is at a maximum distance from a switch, the activation feature and the switch always being separated by a distance that is less than or equal to the maximum distance while the light field is visible to the driver as a virtual image, the maximum distance being less than one millimeter;
rotating the mirror holder to reduce the distance between the activation feature and the switch until the activation feature actuates the switch; and
in response to the actuation of the switch, transmitting a feedback signal to calibrate and record the rotational position of the mirror holder in a memory device.
