I have a 2005 STS with nav and while I haven't tried to play a music DVD, I have not had a problem playing CD's that I burned on my pc. You might want to try burning a cd,using a cd-r using a mp3 file system and if it works look at the type of dvd, and the file system being used and if it doesn't then I would look at the player in the car. I have used Nero Burning Rom, Roxio Media Creator, and Windows Media Player to burn my cd's and they all seem to work equally well. Hope this helps- See Ya!!
