Don't know if this is old news or even news, but if you have a RIO 500 and are running any firmware under 2.15, you should upgrade. There are lots of new features and menu choices (ID3 Tag, Artist, Title, Album etc.), but the biggest bang for me was the increase in volume. It will go much louder. The older firmware has a volume range of 0-20 and the 2.15 goes from 0-25 with a noticiable increase in volume. Bass/Treble also recieved an increase in range. I upgraded from 2.13.
