Abstract
A sound system for a motor vehicle and a method for defining a functional scope of a sound system include a control unit, an input unit for operating the system, a display unit, a unit for generating source data in the form of audio data, an amplifier unit for amplifying the source data, one or more speakers, and a bus system that assures transmission of the source data and control data for controlling the units among the individual units. At least one unit other than the control unit of the system has a memory assigned to it, in which the functional scope of that unit is represented. The functional scope can be transmitted through the bus to the control unit, and the transmitted functional scope can be used in the control unit for at least partially forming the functional scope of the entire system. The control unit, the input unit and the display unit are connected to one another in such a way that through the use of the display unit, operating menus required for operating the entire system can be shown in accordance with the functional scope of the entire system, and the operation of the system can be performed with the aid of the input unit on the basis of displays in the displ…
