Remember, the E70 does have 8 programmable buttons.

Just setup one for "vent" settings.

Also, you do know that if you pull the iDrive knob in a direction and hold, it will go there? Example: pull the iDrive knob toward you for 2-3 seconds... entertainment menu.

I don't see the big issue with iDrive, combined with voice control I think it works great.
