The following is the owner's manual for your 2004 Dodge Neon:

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.

my 2001 ml 320 when i press cd button it says no cd player installed massage. There is 6 cd changer in the back of the car ., Any suggestion for fix the cd player?
Please help.

Try turning off the radio and disconnecting the battery for 1 min and then reconnecting the battery. Turn on the radio and see if that reset the radio so you can get your CD out and try cleaning the CD player with a cd player cleaner. Note you have to make sure the radio is off before you disconnect the battery. Good luck and hope this helps

to take the radio out you need to remove the big plastic piece around it. to get the radio out there is a special key that fits into 2 little holes on the side of the head unit.

I have the same problem with the 2006 sentra

I had to take the changer out of the console and get the CD that was hung up. I then replaced everything.

reset your radio by unplugging your battery for an hour and plug it in to see what happens. if not then time to replace. these cd players look nice and all cuz they are 6 disc but dont read mp3 well and get stuck easily with thicker cds
