First, do they have the stick on CD labels?
If so, once you do get them out, NEVER use them in the Trac radio. It produces to much heat and the labels become loose and from there nothing good happens.
I installed a 12 volt Computer fan on the backside of mine just because of the heat it created. The dash was always hot and I felt it was not a good thing to do to the various electronics.
To remove them, you can pull BOTH fuses and reset the radio. Sometimes that is enough to get the out. If not, you will need to pull the radio and disassemble it to a degree. It is fair complex but not too difficult. Just give yourself time and don't walk away as you will have screws and what not laying around...
Some have said they used a knife to "help" the door open and "help" eject the CD's but I think this is the lower percentage to be honest.
