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.

A method of data exchange in a vehicular multimedia system that includes an interface unit and a plurality of multimedia units each connected to a data bus configured as a ring line in the vehicle, comprising:
- establishing a radio connection between the interface unit and an external unit;
- receiving from the multimedia units requests for the radio connection with the external unit;
- and
- coordinating/arbitrating at the interface unit requests for radio connection to the external unit.
A multimedia system suitable for use in a vehicle and capable of communicating with an external unit, comprising:
- an interface unit;
- a plurality of multimedia units;
- data bus configured as a ring line in the vehicle, wherein said interface unit and said plurality of multimedia units are each connected to said data bus;
- and wherein said interface unit establishes a radio connection with the external unit, and wherein said interface unit comprises a coordination unit that coordinates requests received over said data bus from said multimedia units for radio connections to the external unit.
A multimedia system for a vehicle comprising a plurality of multimedia units connected to one another by data bus laid as a ring line in the vehicle, wherein an interface unit is situated at an arbitrary point of the ring line and is configured to establish a radio connection between the multimedia system and an external unit, wherein said interface unit coordinates requests generated by the multimedia units, said requests being for radio connection with the external interface.
