did the navigation/idrive units change in 2011 or once the seven button idrive came out they're all the same? (the reason i ask is because my experience with audi they went from mmi-2g, mmi-3g then mmi-3g plus all within two years or so... curious if BMW did the same with their idrive or if it has been the same since the change to seven buttons.)

i always ask them not to wash the car or do any favors for me... just service/repair and call me. somewhere in-between me telling them that and picking it up it winds up being ignored despite having it on the RO.
