My 2013 SHO with the very nice Sony stereo has decided my very hard rock MP3 disc is so awesome it refuses to eject it and has now decided it really sees "no disc." It wont play it; it tells me "Ejecting Disc" but gives nothing; then reports "no Disc." I disconnected the battery for a few minutes but still got nothing. I saw on a few other Ford Forums the suggestion to hold the Accessory On button and press the CD eject button; still nothing from that suggestion. Any guidance would be appreciated.
