I've got a new 2007 A4 3.2 s-line with the bose stereo... It playes MP3 CDs just fine, but, about every 8th time I get into the car and start it up, it starts playing my disc (an audio book) at the beginning of the disc, instead of remembering where I am on the disc and resuming from that point.

Has anyone else had this problem? I don't know if I've got a bad unit, or maybe just buggy firmware, or what...

Thanks!
