Radio failures occur regularly after all they are prone to shorts , over voltage, surges, incorrect polarity hook up etc. The problem I think is that the radio installer hesitates to work on your unit because he may want approval from bmw to work on it possibly under warranty. Some vehicles state that any unauthorised work voids warranty. Clear the air with the radio teck and find out his problem exactly and if still in doubt take it somewhere else.
