Hi,
I basically have the same question as Josue335i from above. I already have Bluetooth option and aux in armrest but no USB, I have a 2009 318d with professional radio but no MULF next to the battery (in fact there is only enough room for the batter and nothing else in the compartment).

Could the MULF be somewhere else? How could I have Bluetooth without one?

If there is one, can I easily add USB?

Sorry for all the questions, only had the car a week and have been looking for answers since!!
