I love how the color changes constantly, and how it reads mp3 discs and tells you the name of each song (if you didnt already know it). It also allows you to sort music into folders by artist, genre, etc so you can find exactly what you want easily. Flip-down detachable face is nice too!Interesting story- I went to Best Buy to get it, and there were many Italian women (6 or so) outside selling $400 worth of gift cards for $300. I took them inside, got them scanned, and sure enough they had $400 on them. So I bought them, saved $100!!! Total cost of unit+parts+4yr service plan (they switch the unit if you sell car, replace it, you can upgrade later, etc) for $40, definately worth it. All in all came out to $415, but with the $100 I saved I only paid $315, so Im stoked. Anyways, I have a question. How the hell do I turn the bass up? I read the manual but it is so oddly worded. Anyways, any help would be appreciated, and for those who are wondering, the sound quality is great, ergonomics are great, looks great, great price (315 ), and mp3 now woohoo!
