Odd for me (even after a year of ownership), is the backwards step of not allowing any real functionality of the bluetooth system from the DIS display (the screen between the instrument clocks) using the steering wheel controls.
Only your last call list is present, whereas on my older Scirocco, you could retrieve the complete phone address book and quickly search for a contact by scrolling (and holding the scroll button down would quickly change between alphabet letters). Now, (certainly on Nav Pro at least), VW want you to either using the voice control (which can be very flaky at best), of use the touchscreen whilst driving).
A backwards step I think.
Oh, and whilst I'm ranting, why is it that we GTD, GTI & R owners get a nice colour DIS display as standard, yet apart from the door open warning graphic, most things are monochrome (Nav directions for instance). If you ever look at the new A3 model with the colour display, everything uses colour and looks much higher quality as a result !
