telephone - bluetooth? - navigation - video (dvd) - mp3/wma and etc... basically the core iDrive function. The language is English UK (phew). Not sure whether I need to have or nice to have all the features. Will seek BMW Workshop expert with regards to the conversion. Stay tune.
Otherwise love the car to bits. Active Steering takes abit of getting used to. The 3.0L engine mated with the 6 speed auto is lovely. (used to drive the 528i with 5 speed auto - double vanos).
