this retrofit will only work with the updated ccc version which were the march '07 builds and later. if your original idrive controller has the "mouth shouting" button then i don't believe this will work plug n play. i wanted to know before i ordered the parts if the controller retrofit needs programing or software updates to work. i know some needed it but did anyone do it without having to get a software update? and does the dealer charge for a software update?
