Concert II or III, how to tell?

What model of Concert stereo goes in a 2007 A3? Concert II or III? It's only labeled Concert in the front. Is the Concert II or III compatible with MP3? Any comments would be much appreciated.  

To the best of my knowledge:

• the Concert II does not play MP3 CDs, while the Concert II+/III does
  
• the Concert II+/III is standard in the '08, but not the '07 (in the US)
  
• the Concert II+/III is double-din while the Concert II is single-din
  

not even going there lol

Thanks for the info. I have the 07 single din concert. To bad, that means I either have to burn lots of CDs or get an iPod connection. Oh well!!

Yep, I went with the ipod.  The kit installed easily and I bought an old 2 GB nano and love it!

Which iPod kit did you use? Does it work with the steering wheel control?

I went with the GROM Audio kit from ebay - it's perfect.

I did a search for GROM but all it came up with was snow boots. Would you happen to have the sellers link?
