However, it is only showing it in the upper left hand corner and it is about a 1/2 an inch wide. This makes it difficult to read. I wish it scrolled across the bottom.
There is one local radio station where I live which uses RDS. When I tune to this station, the song name
DOES scroll across the bottom of the screen. Assuming they get it right, that is. About 50 percent of the time it's wrong. On my player, and on this station, the upper left corner of the screen is for the station call letters.
First, sanity check: What version of the player software are you using? Mine works as described above using 2.0 final.
Anyway, there's a very good chance that the RDS problems you're seeing are the radio station's fault. U.S. radio stations are well known for poor RDS implementations. FAQ entry
