I have the GPS in my 2001 E320 (MB calls this the COMAND module). I like mine but you're right that the navigation is pretty bad. There should be an issue date on your CD. Every year, at least up to 2009 or so, there is an updated disc. I have found and bought most of mine on ebay. There are no hardware or firmware updates that I know of.
As far as the audio portion I think the volume level must be adjusted while the woman is talking and that is independent of the radio and audio CD volume. Plus there is a separate owner's manual for the COMAND units. You might be able to go to the MBUSA and download for free, or buy a hard copy on ebay too.
Good luck and welcome to the forum.
