Something about TMC box, FIS and MFD

[roby]

Hi all, i am confusing with MFD ver D and G, FIS, TMC box.
Seems that RNS MFD ver G get ability to communicate thru Can-bus, and the TMC box with part number 3B0 919 894 A not only get the function of TMC but also as a Can-bus gateway, so both install this TMC box and ver G MFD, the cluster with big FIS screen will display both radio/cd informations and the routing information. Is that true? and what about a single ver D MFD without TMC box? can it also display the routing information in the FIS tacho?
