Usually, a single control is used to control both left and right side mirrors. A mirror is selected by a switch or a knob. The mirror selector usually has a neutral position with no mirrors selected, to prevent accidental changes of the view. The position of the selected mirror is adjusted by a
joystick, a four-way knob, or other type of position control. In luxury designs, power mirror settings may be memorized together with settings of
power seats. ==References==
