cd fails but AM/FM works?
no year car told.2007 TO 2018 MADE ,CALLED 'JK' SERIES.
just buy the car with dead CD?
just have only one CD? disc?
I have 2008 wangler here, near mint.

first off try read music CD , (called CD_DA) sold in brick stores
not MP3, not CD-R disks recorded try a REAL MUSIC DISK
OR BLOWN OUT THE CD HEAD INSIDE. OPTICS, CARS TEND TO GET DIRTY,.
MY JEEP HAS THE "RES" RADIO HEAD,+ cD
my users guide states

This radio is capable of playing compact discs
(CD), recordable compact discs (CD-R), rewritable com-
pact discs (CD-RW), compact discs with MP3 tracks and
multisession compact discs with CD and MP3 tracks.

the users guide covers this, lost it, well it is free online.
users guide page (in your glove box)
shows page 230 more mp3 rules. (DIY disks)230 to 233 a whole list of complex restrictions on MP3 DIY record-able discs

no year told at all.matters huge. year 2001? to PRESENT.
2018 ford ended CD support.
all else works? FM /AM ,?
try 2 CD called CD-DA music disk. called brick store CDs"top labels"
many CD-r disk record-able do not play in cars.
many CD with Mp3 music do not play
the owner guide in the glove box does tells what the radio CD plays for the OEM radio sold day one. new.
watch out some Radio.or head end CD rigs can get 2 CDs jammed inside. (for sure slot CD type) kids do that most. failing to eject first the ram in a 2nd, causes huge damage.

The motors for the eject tend to strip out (several very small plastic gears. Hopefully this is not the problem because it is impossible to find parts. The other option is that dust/dirt have built up inside and the sensor does not feel/see the disk you are trying to insert. Use a can of compressed air (office store - sold to clean computer keyboards, printers, ...). Spray into the cd slot to remove dust.

Usually there is a hole in close to the cd slot, where a pin can be inserted in order to push out a cd manually or a similar manual override.
Which CD player/ radio are you using?

so is this a stock RAD/cd?
stock JBL 6 disk player in dash>? or? what? name and model #
mp3 and wma format. but not DVD
or
JBL premium 4-disc in-dash CD changer
io the single disc player, 3 kinds sold. new.

and now comes the big question.
TELLS where you got the disk, or name it, or tell how it was made if home made. we dont know that.

is said CD a CDDA? or not. (always try CDDA first)
is CD a real music disc. from a real store, CDDA, is that.
or CDR, or DVDr, or CDRW, or other record-able media
is music MP3? files.
see, the old units dont play modern media.

try 2 real discs, not scratched.
do they play?
one other way, is to name the radio, brand, like JBL then get the
p/n off it. (hard) then look up the product data sheet on it,
bingo, what it can and can not do is there.

but this does it all, mostly
does what yours will not do.

you could try to power down the radio, by either pulling the fuses or disconnecting the battery. But usually if everything else works, you will need to have the radio replaced or sent for repairs

Before connecting any cables you must set the dip switch box to the position listed for your vehicle. If you set the dip-switches after you have connected cables to the box, you must disconnect and reconnect them for the changer to operate. All 1992-2004 Honda's are compatible with the Neo Changer except the 2003 and 2004 Honda Accord and all Honda Element vehicles. Some radio models require pressing "Seek >" once to start playing after changing CD or after startup. The radios display will not show the proper disc number after disc six. You can use all 10 discs in the magazine, but the readout will be wrong. This is not a technical problem; the car stereo was designed for no more than six discs. *Due to the direct access disc system, you will not be able to directly access discs 7-10. To access these discs you will have to go to the last track on disc 6 and let it play until it loads disc #7. ( you can fast forward the track, but you must let it play the last 5 seconds of the track, for it to change to disc # 7 Switch to the Neo Changer by pressing the "CD" button. To change discs press "Disc -" and "Disc +" To change tracks simply press "Seek <" or "Seek >" S E T T I N G S F O R H O N D A 1 2 3 4 5 6 7 8 ON OFF OFF ON OFF OFF ON OFF
