An exterior vehicle mirror system has a vehicle mountable support and a support arm. A mirror housing is movable along the support arm between the support and a distal end. An electrically powered mirror unit adjust mechanism can adjust the mirror unit about horizontal and vertical axes. An electrically powered pivoting and extending mechanism pivots the support arm about the support between an extended position and a position folded against a vehicle side. An electronic control system controls movement of the mirror housing along the support arm, and folding of the support arm, independent of an adjustment of the mirror unit. The electronic control system comprises a memorized position for the powered pivoting and extending mechanism.
