With the software upgrade being pitched as part of BMW Performance Accessories, perhaps the parts department has more info. Still, if X6 buyers could order it on a new car in 2010, why not put it on the configurator and give enthusiasts the option to donate another $1500 or so to BMW/dealer's bottom line?
