Although the overall sound is fine, i must say i am NOT a fan of this radio. for those without the Nav unit (like this guy!), the touch screen is useless and lags pretty good. when browsing throught folders for music, there is a pretty good amount of "please wait". when i adjust the volume, the bottom row of "buttons" is coverred up by the volume bar thereby renderring them unavailable until the volume bar goes away. basically i am a fan of buttons that are real. touchscreen is great for things where a button would be impractical.
I hate the auto level adjustment feature. not the auto volume but the thing that cuts the low frequency response for higher speeds. it would be nice to be able to turn that feature off.
