This is the stock unit that came in my 2006 GTI. I live in Germany now and European maps do not work in this unit. The MFD2 should work (it's your job to be sure) with any MkV Golf/Jetta/GTI/R32 as well as the B6 Passat and Eos.
It works perfectly and I will include the Sirius box that is installed underneath the passenger seat as well as the Version 3B Map DVD and an antenna. It will control the 6-disc changer as well as the original iPod interface (does not display info on screen). $450 for everything shipped/insured.
Let me know if you have any questions. I haven't pulled the Sirius unit from the car yet, so there are no pictures.
