Abstract

In a multimedia system for a vehicle, a plurality of multimedia units are connected to one another by an optical bus laid as a ring line. An interface unit, situated at an arbitrary point in the ring line or integrated into one of the multimedia units establishes a radio connection between the multimedia system and an external unit, which for example transmits traffic information to the multimedia system.
