After long using USB audio interface I decided to try the good old CD and to my surprise found out that there is no CD changer in Advance package, while there is a 6-disk changer in Base. How come?! ELS and nav unit have eaten all the space in the unit?

 

Because there's a 15 gig hard drive dedicated to storing music. When a CD is played it's automatically stored on the hard drive.You can store a LOT of music, make playlists, etc., it's more versatile than a straight CD player.

 

Considering that we have a USB audio that can eat many gigs of memory, I personally would prefer to have the CD changer instead of HDD for ripped audio for high quality music.

Anyway this drawback is not serious for me but still quite surprising

 

Interesting. I wouldn't have known as I have the Base
