hey guys am new to this forum and to bmw. i purchased my 330 from a used dealer. the car did not have a control unit for the idrive system but i was told that it was on order. they have the radio now but they are holding it because they say that it needs to be programmed from another car like mine. now my question is are all 3-series idrive system the same? and does any one know a place in socal that will program it? sorry if this sounds rather dumb.
