you have a fault on the most bus network and require diagnostic check.I say most bus but it could be electrical but suspect optical open circuit.

So it was most bus open circuit,ok you have to release voice control componant protection so it will work(on line via dealer only)if this still doesent solve the issue make sure the software version of the voice control is compatable with the radio unit and sound system as you may have to update the software versions.
