Kevin's right, I meant premium Bluetooth - oops

It's a minimum requirement for VW's car net system, which gives you access to googlemaps, live traffic data, weather etc. as well as creating a wifi hot spot in the car. Additionally it has an extra sim slot in the glovebox in between the 2 SD card slots.
Like I say, VW UK don't bring this system (yet) to the Uk so we don't have it.
