Your going to miss out on MDM which is excellent IMHO. Comfort Access is cool but not necessary. I'm not a huge fan of the IDrive
, and the BMW Nav leaves plenty to be desired if you ask me. I've searched for very well known hotels, restaurants, and golf courses on the points of interest and they are nowhere to be found. By comparison a good friend of mine has an Acura TL and his Nav is touchscreen and has never failed to find exactly what we were looking for when looking for a restaurant or something of that nature. It is also much more user friendly. BMW dropped the ball in this department if you ask me, they need to go to a touchscreen system soon and ditch the IDrive, although I haven't heard anything indicating that they will. I would suggest getting it, the MDM alone is worth it.
