There is a fellow at the VW forums that I attend, he was able to adjust his phatbox to work with the VW MFD navi unit. This unit was only available in europe, but some people in NA started to import them, and managed to install them in US cars. I think that the phatbox would not work with this unit without some modifications. I'm not sure what modifications he has made, but it would be big if he figured out how to enable ID3 info.
