The system in my 2011 X5 is not much more advanced than the RDC in my 2001 M5. Sure, the X5 has a pretty screen to look at if you have Navigation system but there's no interface and really no information displayed except that the system is 'OK.' That's about as much information I get with my M5 except for the pretty screen. You'd think 10 years of technological advances, a pressure sensor in each wheel and a 9" monitor would actually add something.
