Really
The newer radios (05-07) are better radios but have so much default treble.....very 'brassy" sound
Why would they not have this EQ is a total mystery!!!
They sound very good with the optional factory subwoofer in V70s, but if you have an S60, you're sort of screwed unless you install a custom sub
If you read the hidden menu that was posted avove you would see what the factory defaults are
Some settings are 0, some are 4s etc
