It may work for the navi but tell me how Idrive can beat me changing a radio station or AC setting in a 1/4 second by pushing a single conventional button
Hmmm, I'm not sure what car you are talking about - I could not change the radio station or AC setting in my GS430 in 1/4 second as there was no conventional button for either........
I can do both in my I-Drive equipped car however....
Seriously, the hidden steering wheel stalk might have allowed changing of station in the GS430....
