Hmmm. Well everyone keeps saying (above, anyway) that the stock head unit is crap. But I beg to disagree. Now I have the USB unit, so that might make a difference (though I doubt it) but that with Alpine speakers and Eclipse amp sounds great in my car. I think that it all may be a case of "the grass is greener..."
The worst thing about the stock head unit, and the dash info for that matter, is the puny orange LED lighting that can't be read during daylight hours.
--otherwise, I have no issues with mine, sans the desire for nav and usb.
