I've driven about 300 miles and listened to a CD and my iPod. I think the sound is very good for a stock unit in this price range car. I haven't checked any of the settings, however my '08 Enclave sounded much better after I adjusted the bass/treble from the factory settings. XM isn't a good test since the source quality isn't real great. It has plenty of bass for what I listen too, country, '50-'60 and jazz. If you want the window vibrating bass it isn't there, but most of the unit I've heard with that overwhelm the other tones.
