Instrument cluster as gateway
The instrument cluster is the interface between K bus, PT-CAN bus and diagnosis bus. The
instrument cluster communicates with other control units in the car via the K bus (single-
core) or the PT-CAN bus (two-core).
On-board computer
The on-board computer functions are the same as those of the E46. A new feature in the
E85 is the possibility of combining time and outside temperature in the display depending
on the equipment specification.
On-board computer display in navigation-system on-board monitor
In cars equipped with the High navigation system, the on-board computer functions are
displayed in the pop-up on-board monitor (Central Information Display CID).
The "Distance to junction" navigation data is displayed in parallel in the instrument cluster.
Settings (e.g. units or reset) which are made at the navigation system controls using the
rotary pushbutton are sent by bus telegram to the instrument cluster.
The date can be set at the navigation-system controls. The date is administered in the
instrument cluster and shown in the onboard monitor.
