Also saw this update on the message boards...anyone have experience? Gracenote Data base update? Notice a big difference once updated? The below link has more info on software update for RER and links to forum discussion and download/install instrucitons:
Software update MyGig RER 2.402
I found this info re "Gracenote"
The Gracenotes database identifies music tracks and provides song, artist and genre information for your music stored on your MyGIG hard drive or played from your MyGIG CD/DVD so that you see the actual track information instead of seeing tags like Disk 1 or Track 1. Updating your database will keep you up to date with database information from the latest songs.
The Gracenote updates are locale specific as opposed to radio specific as people in different parts of the world tend to listen to music from different performers so the database of songs is different within different global regions.
