if you want a cd player, better sound, aren't going to go amp crazy, and don't want to lose a lot of money if it gets stolen, i'd definitely recommend this:
Alpine CDE-100 CD receiver at Crutchfield.com
I put one in my cabrio because there's no logical reason to put an expensive radio in a convertible, and i really really like it. The red matches perfectly and the blue is a pretty good match too. And the usb port means you can just buy a cheap little flash drive and just dump some mp3s on it and have way more than 6 cds worth of music you can control through the deck. I use it to plug my phone in and it reads the 8gig card in my phone perfectly and it also charges my phone while playing off it! (how awesome is that?)
