I did not want a lot of options for my car... I only order (full)M-sport, 6FL/USB port, metallic paint, heated seats, 6MT, and leather seats.
On the EU/German spec models you can order every ala cart. But you pay dearly for every little option!
Interesting. In my '08, that switch operated the inflatable side bolsters which came with the sport seats. The lumbar control is a circular control located a few inches to the rear - and was only available with the ZPP and power memory seats.
