I don't think it will even play CD-R's with MP3's on them...But I'm not sure...I live in Canada and have a 6 disc changer in my speed and it plays burnt MP3 discs. But I hear the US version does not. Maybe someone else could chime in and verify?
I think starting with the 2007's they played MP3 CDs. I have a 2008.5 and it plays them. You may be able to swap out the player for one that does, but I'm not 100% sure of compatibility. Have a read here for someone that did it on a 2006.

If you do swap it out, try buying a secondhand player from ebay or one of the bigger salvage companies. It will cost about $100 verse $400-500 at the dealer.

just wondering if it will play dvd discs with mp3s on them
mjstew said:i might do that. the seller of the car gave me an fm transmitter for my ipod, and i was surprised to hear the quality. as soon as the car starts, i can hear the buzzing of the semi vacant fm setting, and then it dissapears to silence once the transmitter comes on, so i may stick with that for a while before i just install an ipod mod.
