I have a '08 3.0si and I've tried playing CD's in the single CD player (I have no premium sound) and it says that "no supported audio..." message. I put the CD in the DVD player and it recognizes it and plays.
This is really annoying especially when I'm trying to use the Nav system. I've done a search but I haven't been able to find any info. about this problem.
I scheduled an appt. at BMW of Dallas next week to see what's going on. I was wondering if anyone else has had this problem and what they did to fix it.
