The cd player is toast. I had the same issue with my 08. TAKE it bAck they will replace it. It should be under warrenty. Mine still was after installing subs and some other aftermarket stuff. I went through 4 cd players before I got one that worked. Then I replaced it with aftermarket. But not the point . Point is its toast. Sorry.
The ford head units arnt very good, I ended up replacing mine with a alpine and getting sirius radio, a Ipod connector and bluetooth with it and its great. My car had a 6 disk changer(although mine was a 2002) and I got the same error.
