Factory DVD Nav - Mp3 Support missing?

[slidersv]

Hello. I had bought my H3 a couple of weeks ago. It's really great, except one little thing. I have Luxury package and Factory DVD Navigation, which means i should have gotten monsoon+6CD changer with MP3 support with the package.
It the manual there is nothing about DVD navigation (It says to see the manual for the Nav). It plays audio CDs fine. But whenever I insert Mp3 CD or Moovie DVD it reports a DISK ERROR.
So my question are:
- Can it play mp3 CDs?
- Can it play DVDs?
- Can I itsert more CDs somewhere? (well, not anywhere just to be able to play them)

Or it does not support any of it and i lost the radio that came with the Luxury package when i got the Factory DVD Navigation?
