My Ride: 2000 328ci TopazBlau
To clarify on my last post here is an example of data that is on the ibus.

The insterment cluster sends current speed to the radio on the ibus.
the steering wheel buttons also send their data to the radio as well.
When you unlock the car, the GM5 sends a command to the LCM to turn on the dome lights.
