Abstract

The invention relates to a control device for controlling vehicle functional units. There is a need for a control device which can be used for controlling a variety of different functional units without there being uncertainty with respect to what function is being controlled. The control device is adapted to control a selected one of a variety of different vehicle functional units. At least one display element is associated with the control device. The display element displays an image associated with the functional unit which is being controlled by the control device.
