Maybe I'm missing something here, but it doesn't seem possible to make any alterations to music imported onto the hard disk (Nav Pro system) such as renaming or deleting tracks or albums. While the manual talks about it, as far as I can see it only refers to CDs that you've imported and not to MP3s that you imported via USB.

Is this really the case, as it makes it a real pain in the *** to make even small changes to the stored music without wiping it and re-importing it all again.
