An inventive rearview mirror assembly (10) is disclosed in which a microwave antenna (54) is mounted so as to receive transmissions from one or more satellites through the front windshield (20) of the vehicle (25). The microwave antenna may be tuned to receive satellite transmissions from a position identification system constellation of satellites, such as GPS or GLONASS. Additionally, the microwave antenna may be tuned to alternatively or additionally receive transmissions from at least one communications satellite, such as a CD radio satellite. In addition to the inventive rearview mirror assembly, an inventive electrical control system is disclosed that may be used as a navigation system, an electrochromic rearview mirror control system, a head lamp control system, a vehicle compass system, a vehicle data recorder system, and/or a vehicle odometer verification system. In each of the above systems, new parameters are made available by the microwave antenna to perform control operations not previously performed.
