A rearview mirror for a motor vehicle comprises an internal frame
supporting a reflective element and a motorized tilt actuator assembly
for adjusting the reflective element about perpendicular axes. The
reflective element is attached to the internal frame through a pivot
connection. A positional memory module comprising a separate assembly is
supported by the internal frame adjacent the pivot connection for
electrically determining the horizontal and vertical tilt of the
reflective element at a selected position as a change in voltage through
a pair of simple electrical circuits. The reflective element can be
returned to the selected position by adjusting the horizontal and
vertical tilt of the reflective element according to the changes in
voltage.
