Abstract:
1. A sound system for a motor vehicle comprising a control unit, a first input unit to operate the system, a display unit, at least one unit to generate source data that includes sound data, an amplifier unit to amplify the source data, at least one loudspeaker, a bus to link the input, display, source data and amplifier units to assure transmission of source data and to control the input, display, source data and amplifier units that are distributed over the vehicle, and at least one system unit, different from the control unit and having an associated memory in which a functional scope of this unit is stored, such that this functional scope can be transmitted over the bus, and the transmitted functional scope can be drawn upon at least partially to form the functional scope of the entire system, where the sound system further comprises a second input unit where the first and second input units have a memory in which is stored a priority value for each of the input units, that the first and second input units conduct their priority value to units connected on the bus, that the units of the system, other than the control unit, together with their associated memories form the transmitted functional scope in dependence on their priority value and conduct the formed and transmitted functional scope, via the bus, to the first and second input units with an appropriate priority value, and that the first or second input unit with this priority value draws upon the transmitted functional scopes, formed in accordance with their priority value, to form its functional scope.
