X1 iDrive, same as what's in the X3/X4? When was it last updated?
I know BMW usually does a life cycle impulse (LCI) or "mid cycle refresh" to their products, but how does the currently available X1 iDrive compare to the newer BMW products? Is it a generation behind? I noticed that the handwriting input method (finger touch pad) is not available on the X1, so at minimum some features are not available/enabled (but they appear in other BMW products like the X3, etc.).
How old is the GUI interface in the X1, and when was it last updated?
