That's a great-sounding and easy-to-use headunit (the 9845.) My bro just put one in his car a few weeks back and it sounds good even with the factory speakers for the time being. The only thing I don't like about it is that you can't start to shuffle and stay on the track you're currently listening to. To me, it's pretty annoying, and it wouldn't have been tough for Alpine to program it that way..
