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 units and to assure transmission of source data and control data to control the units between the units that are distributed over the vehicle, and at least one system unit 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 is drawn upon at least partially to form the functional scope of the entire system, where the sound system further comprises at least one more input units where the input units have a memory in which is stored a priority value for each of the input units, that the input units are apt to conduct their priority value to the other units via the bus, that the units of the system, other than the control unit, together with their associated memories are apt to form the transmitted functional scope in dependence on their priority value and to conduct the formed and transmitted functional scope, via the bus, to the input unit with an appropriate priority value, and that this input unit with this priority value is apt to draw upon the transmitted functional scopes, formed in accordance with their priority value, to form its functional scope.
