With Business Radio:
The MID requests the data from the instrument cluster.
The instrument cluster is the "master computer" and all trip computer data is calculated in the cluster
Once the MID has the data, it is simply displayed.

With navigation:
Done exactly the same way, except it is the navigation computer that requests the data.

NOTE: when changing from MID to nav, the car needs to be re-coded, so that the instrument cluster talks to the nav instead of the MID.
