Alpine dvd navigation and audio in EUROPEAN Honda Accord Tourer
 

I have just bougt an Honda Accord Tourer (european model) !!!
It is equipped with an Alpine OEM DVD navigation unit (7" touch screen) and
Alpine OEM stereo with integrated 6-cd changer.
does anybody know about any possible extra's/extensions from Honda or
Alpine, such as a MP3-compatible player/changer? is there an extra input on
the stereo (aux)? where can I get map-updates for the navigation system? can
I connect a GSM like with some Alpine stereo's???
