An interior rearview mirror system for a vehicle includes an interior rearview mirror assembly having compass circuitry having a multi-axis sensor and associated circuitry. At least a portion of the compass circuitry is established on a semiconductor substrate using CMOS technology. The multi-axis sensor comprises at least first and second magnetoresponsive sensing elements. The magnetoresponsive sensing elements may be disposed in the mirror casing and move in tandem with the mirror casing and the reflective element when the mirror casing is adjusted by the driver of the vehicle. Processing of an algorithm by a microprocessor of the interior rearview mirror system determines a directional heading of the equipped vehicle responsive to a sensing of a magnetic field by the magnetoresponsive sensing elements and automatically compensates for a deviating magnetic field. An information display may display the directional heading of the equipped vehicle.
