The driver information Systems on the E46 follow the design concept started with the E38. The information is presented to the driver in two main areas, the instrument cluster and the center console area. The E46 makes extensive use of bussing for communication between control modules and reduction in wiring.

The instrument cluster in the E46 is similar in design to the basic cluster installed in the E39. It uses the pictogram display block for check control and lamp failure warnings.

The Bus links used in the E46 include:
The K-Bus: For communication between all body modules and driver information systems.

The CAN Bus: For communication between the engine management control modules and the instrument cluster.

The D-Bus: For diagnostic communication between the vehicle and the DIS and MoDiC testers.
