Hello-I just purchased a 2008 Volvo S40 2.4i. It does not have a CD changer or iPod USB connector, but does have the AUX jack. In reference to the CD player's ability to playback MP3s, I am reading different stories about MP3 playback. Does anyone know for sure if my stereo will NOT playback MP3s? I feel like some of the things I'm reading assume that it CAN playback MP3s even if it's not the CD changer model. However, when I insert a CD loaded with MP3s, it just says it can't read the disc. Any thoughts? Thanks! Jeff
