After reading this post I got excited and burned myself a MP3 disc with no subfolder off i Tunes and all i got was a hissing noise with computer noise a bit like when you used to load programs from a tape recorder back in the 80's I could not change trackers either

My car is a 05 car

Just one other idea what about the disc you got to work up load it some where so we can all download it to make sure we are all getting the music the same way?
