It's probably like BMW's new iDrive setup. They have this giant push-button twist knob in the center console that controls everything on the car. You have to twist, turn, push, tap, and press to get what you want.
Hell, the 1977 7-series I looked at had more buttons than I knew what to do with. There was a button or light for every damn thing on the car. I can't imagine things have improved.
