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 .
