A vehicle audio system includes an audio central unit, to which one or more further audio components are connected via a first vehicle data bus, and interface means for data communication between the first vehicle data bus and a second vehicle data bus of another type. One of the audio components is an audio gateway unit that contains the interface means, and is formed as an independent component separate from the audio central unit. In addition to data bus gateway functionality, the gateway unit also includes an amplifier functionality, a tuner functionality, one or more further standard audio functionality spanning vehicle types and/or countries, and/or one or more further audio functionalities, which are implemented so as to be parameterizable according to specific vehicle type and/or country. At least one vehicle loudspeaker is connected to the audio gateway unit, which has a control unit that puts the audio gateway unit into an emergency operation mode in the event of failure of the first vehicle data bus, the audio central unit or further audio components. In the emergency operation mode, amplifier and tuner functionality are provided.
