Hello, where 212 EZ 06.12 comes, when I have on “Service” and “Dachzeichen”, after switching off the engine or when boarding always the following message in the AI: Radio error – restart with + Now we have no radios in our taxis for a long time. Can you delete the radio somehow from MB??? So that I can only set on or off on the menu “Vehicle” roof signs??? So no more “Service” or “Private” Thank you for your answers!
