Hi all hope someone can help I have a 2011 E350 with DAB etc , a few weeks ago I activated the read out messages aloud option in TMC in the Navigation menu and since then i cant get the damn thing to shut up, am not really interested in the messages as they are usually read out when your already in the jam anyway but am befuddled if i can find an option not to read out the messages, can anyone tell me how turn them off?
