Anyone know how to name playlists on the usa spec Ipod adapter. I have nav screen so the playlist names should show up on there, but they only show up as numbers. I tried naming them GM1, GM2, etc like in the manual, but didnt help. Any tricks. I have mine runnin off XM1 if that helps. Its a little confusing to use, but it works awesome, I think it will help out if my playlists are labeled.
