Questions about iPod integration...

I've been searching through these forums and others for a while now, and while there are many posts over this subject, I cannot find any definite answers to my questions. So please bear with me and forgive me if ask a question that has already been answered. I would like to connect my iPod Nano to my factory Concert stereo, with Bose, in my 2002 Audi TT ALMS Coupe. I do not wish to replace my head unit and I do not want to use a FM transmitter. I want a good CD quality connection and I know the connection will take the place of my factory CD changer. I've found two promising kits, the DICE i-Audi-R and the Axxess Wire-Tunes. I was wanting to know if either of these kits (or any kit) will for sure display the iPod track information on my stereo and the MMI cluster display. I know these kits are supposed to support this in most vehicles but I have not found out for sure if they will in the TT. Also, as I understand it, the DICE setup replaces the Dension ice>Link Plus, which has been discontinued in the US, correct? And does anybody have any experience with either of these kits in a TT?

Thanks in advance!
