A vehicle audio system has an audio central unit to which one or more further audio components are connected via an associated first data bus, and are interfaced for data communication between the first data bus and a second data bus of another type in the vehicle. One of the audio components is an audio gateway unit which contains the interface, and is an independent component separate from the audio central unit. In addition to the data bus gateway functions, the audio gateway unit includes further standard audio functions spanning vehicle types or countries, or further audio functions which are implemented so as to be parameterizable according to specific vehicle type and/or country.
