Well Porsche should get an " unclear on the concept " award then. What's the point of paying $1000 option of a multifunction wheel if you can't scroll through your favorite radio stations w/o taking your hand off the wheel . That's like not being able to move to next or previous track on the CD - wait - maybe it can't do that either .
While on the move , those two functions and volume adjustment are 90% of the use of these type str wheels I've used the last 15 years .
