Did you ever tried to use the rotary dial for text input? I gave up immediately. The car has a regular screen regular, no touch. Something is good only when balanced.
I haven't had many, so I do have a touch screen. But I've tried the rotary input on a rental 2 series that had a dial but no touch screen, and I had to use the GPS.
Yeah, agreed on a rotary dial being terrible for text input. That's where a touch screen shines. But you shouldn't need to do anything requiring text input while driving.
