For the data exchange with external, digital components, the radio (A2) is connected to the instrument cluster (A1) via CAN interior (CAN-B).

The CAN interior (CAN-B) makes the following functions possible:

Digital Data Bus (D2B) 

Data can be exchanged between external audio components, the telephone system and, if present, the voice control system via the D2B. Control data as well as the actual audio signals (e.g. music from CD changer) can be transferred.

IMPORTANT Information issued by the radio (A2) is coded message oriented and directly sent to the CAN interior (CAN-B). The instrument cluster (A1) recognizes this message and then actuates the multifunction display (A1p13).

IMPORTANT Communication is also sent via the diagnostic interface of the radio (A2) between STAR DIAGNOSIS and all other components of the digital data bus (D2B).
