The connection via bluetooth is sub-standard and Mercedes dealer admits 200d command module is weak. No problems prior model years and dongles or with 2010 and after. Seems rediculous that MB will not address this beyond saying that was a bad year for our bluetooth. impossible to use phone reliably hands free.
