It appears to me that the Symphony head unit in my 2007 A4 reads and plays the MP3 files that are ona CD in alphabetical order. Therefore, "album" order or "actual track number" order is ignored. The fix for this is to imbed the track number in the file name. For example, the first cut on Abbey Road would be named "01 - Come Together". Of course this looks like crap and takes up several spaces on the screen display. Does anyone know of another solution to force the head unit to recognize and play the songs inactual track number order? The track number is on the CD as an IDE tag for each song. Thanks, JMP
