Multimedia interface e60 for jap spec

[gppaul]

How do we know if i have multimedia interface installed in the car?

Does adding in booster (fm radio) neccesarily need to have the above device installed first?

Nowsday simple radio programming allow u to tune to local radio...

No need to add booster
