When BMW first introduced its i-Drive computer controller in 2001, the big knob that controlled everything from the stereo to the air conditioner to seat settings was widely derided as just baffling. Fortunately, BMW didn't give up on the idea. Since then, it's improved and is, today, one of the easier "infotainment" systems to work with.
In the 7-series, BMW introduces i-Drive 5.0 with some new touches... literally. The system now includes a touch-sensitive screen, just like on a smart phone.
But touching is not absolutely needed. There's still the knob and buttons. There's also something new called "gesture control." Sensors mounted in the ceiling can detect hand movements. For instance, twisting your hand can control the stereo volume. Swiping the hand to one side, the way you'd wave off an offered plate of hors d'oeuvres, rejects an in-coming phone call. Jabbing two fingers toward the screen can trigger a programmable pre-set function you've selected.
