An interior rearview mirror system for use in a vehicle includes a mirror support
assembly for attachment to the interior of a vehicle. The mirror support assembly
comprises a first electronic accessory such as an imaging sensor. A reflective
mirror element is disposed in a housing, the housing being pivotally adjustable
about the mirror support assembly via a pivot element. The housing includes second
and third electronic accessories at least partially controlled by a microprocessor.
The mirror support assembly preferably includes a wire passageway for wires passing
into the housing for the reflective mirror element. The second and third electronic
accessories may be a headlamp controller and automatic dimming circuitry, or may
be selected from a variety of other devices such as a garage door opener, an INTERNET
interface, a video device, a trip computer, a light, or other items. The mirror
assembly may also be in wireless communication with an external device.
