P.99 describes how to load discs:

1. Select and press any numbered button without an illuminated light above it.
2. Insert the CD while the light above the chosen button is flashing and the two lights on either side of the slot are illuminated.
3. Upon insertion, the CD will begin to play, and both the button light and the lights in the corner of the loading slot will illuminate.
4. Repeat the process for loading any additional CDs. The CD playe rwill stop while additional CDs are loaded.

Playing Discs
The radio will show the CD number, the CD track number, and the Track Time Elapsed while the radio is in the CD mode. IF more than one CD is loaded in the changer, the changer will automatically play the next disc after playing the last track of the current disc.

Wow, that's a lot of typing.
I didn't know the 2004 Dodge Neon had such a nice changer.
Good luck.

OK I am no expert but I have has this exact same problem......TWICE. I just addressed it again this afternoon by disconnecting the battery. Once reconnected the radio "initialized" and I was able to eject all cd's and use the player again. I can only speculate as to the cause but it could be because at least 3 of the cd's contained MP3's burned from my ITunes library. I will stick to audio cd's and see if it happens again!

unplug the power to the cd player for about 10 minutes or so. usually that reqiures unhooking the car battery. if that radio is of the anti-theft variety make sure you know the code and how to enter it before you remove power

I have seen this often..assuming there isn't a CD jambed in it....usually means you have to send it out for repair...its most of the time an internal problem.....you can try first is disconnect the plug at the back and reinstall them and turn it back on...If it still shows ERROR....replace the radio... If its a stuck CD...FORD radios DO NOT LIKE homemade CDs, they are to thick, and labels hang it up...If this is the problem use a "needle nose pliers" and extract it the best you can AND DON'T USE COPIED CD's....hope this helps you..GL

radio is bad needs to be removed and repaired
