Bringing this post back from the dead -Have had the 2012 4dr TDI 6sp Manual with tech package for about 6 weeks now. I do a crazy 180mile round trip commute to work and many times its in the dark so Xenon's were non-negotiable for me.
Unless you have true functional need for Xenon's or the KESSY I'd say save your money and do aftermarket NAV/Xenons.
I'm quite underwhelmed by the dynaudio so far and the Nav is a joke for anything beyond point A-B- there is no real time traffic information integrated so for the commuter like me without realtime re-routing based on traffic (which you can get on Tomtom's, iDrive, etc) I almost never use it. The wired and bluetooth interfaces are extremely buggy and wired through the MDI offers no additional features. I'm so sick and tired of having to turn my ringer volume back up every time I get out of my car.
Don't get me wrong, I love the Xenons, the KESSY and Sunroof are nice. The driving mechanics of the TDI are simply great, handling, quiet interior even at 80mph and well selected tire/suspension (again, for the highway commuter like me).
The Nav definitely leaves me wishing I could've gotten the Xenon's ala carte and skipped on the Nav/Dynaudio.
