I know this is old - but THANKS! I think that was
just enough for me to keep it stock.
Selected: Hatch, Loud ON (and CS Auto ON through Menu) and it is loud enough for me. I don't think I'll ever need to set it to 40 anymore. 32 is probably the highest I'll go (using CDs anyway).
I removed it and cleaned off the rubberized coating that was on the face plate. It was getting sticky and made my fingers black if I rubbed it. Now it is glossy (and clean) looking. Used Alcohol and paper towels - which didn't hurt the LCD screen.
