6-mp3-CD changer won't play or eject CDs
 

Ok people, check it out. I burned an mp3 music CD. I thought the CD was finalized, but it wasn't. When I stuck it in the CD changer/player of my Hyundai Azera Limited, I ejected it when I noticed that the last few songs wouldn't play.

When I tried to play the CDs that were already in the changer/player, nothing would happen. Only "Disk Change" appeared on the screen. When I went to try to eject discs, the discs wouldn't come out. Only AM/FM stations play.

Later I read in the owners manual that a non finalized CD could cause a malfunction. This has to be the problem.

The question is, what can I do about it? Any ideas?
