eg. an info screen you can call up for a song which will display some of the other id3 fields ( genre, year, comments) etc.

Is genre, year and comments all you want? Because it already does show this. Press and hold the INFO button on the Rio Remote control. Bam, there's your screen.

But that's all it will do. You won't see all of the other V2 fields that way. This screen only shows what's in the database, which is the fields you see on the Emplode screen only. So if you want to have the details about the lead singer, the producer, the composer, etc., those ID3v2 fields are not shown. The only way that information will reach the screen is if you transfer those details to the Comments field (note: Comments field limited to 255 chars to save memory in the database).
