Abstract: An interior rearview mirror assembly having an adjustable information display device. The display device rotates independently of the rearview mirror to allow both the driver and the front passengers to observe the display when the rearview mirror is rotated toward the driver. The display device displays information about various vehicle systems. The rearview mirror assembly includes a mirror housing for holding a rearview mirror. The mirror housing is pivotally mounted on the windshield of the vehicle so that the rearview mirror is adjustable by the driver into a desired position. The information display device is pivotally mounted on a top or bottom side of the mirror housing to allow the display device to rotate independently of the mirror housing. The display device is attached to the mirror housing through a hollow tubular support arm which has opposite first and second ends, one of the ends being attached to the display device.
