Titan cd420 - music on hold

try a CD with no scratches?
to test a player, one most try many CDs
to truly test it. (a new CD is best ! or scratch free)

next the WORD CD means nothing much, round disc, sure
on such a very old car 2002 CD means this.
plays, ONLY!
CDDA (compact disk, digital audio)
means only store bought disks work. CDDA.

The never works list:
MP3 discs or other music formats common today.
in fact can't play file formatted music.
CDR
CDRW
DVD of any kinds
Bluray

when new, the car had a book on this head end.(in glove box)
stating what it would play, NOT MUCH. CDDA for sure. works and is to be checked first.
much later , it can play many newer formats..
go to walfart , buy any CDDA, off shelf.
try that. see if those work first.
I like Country Joe and the Fish....

you can download a media flash player so you can use the media player.

Sounds like the mounting spindle is out of alignment, meaning the disks you load into the player are not spinning in a balanced, stable position. Without this being the case the laser pickup will not be able to read the disk and the unbalanced disk will cause a noisy hum and you may even be able to feel vibration in the player itself to confirm this. Sometimes the noise and vibration is a disks fault but if it occurs on any disk you insert (and can confirm the same disks work ok with no noise in other DVD players) it will be the players mounting mechanisim that is not playing the game properly I suspect.

Press play, then repeat twice. Display should now show "repeat" "all"

If it is not working, try another cd with fewer tracks on it.

your cd drive lens may be damage and lens preset will be not currect position so if you want to repair you cd drive then you have to turn your cd drive lens preset to currect position. 

Just bought the JX-MP102 find it difficult to use but was able to download songs from a windows xp laptop - plug the mp3 player into the usb port and turn on just as you would for playing music its screen should light up and the computer will pop up a screen with several options click to start windows explorer and from there you can got to place holding music files and copy them the disk letter which represents  the MP3 player. On my machine my main files are on the C disk and a new D disk pops up for MP3 player. I also have a windows vista machine and it also recognizes the player as a new disk drive just like a flash drive.  Unfortunately I can the player to work for a few minutes at best right now even with the music files successfully loaded and playing so I may return it tomorrow. Hope you have better luck.

the screen flash empty disk and i cannot get into the music on the player. how do i empty it so that i can download music again?

was the unit dropped?
is the unit out of warranty?
if yes to both of these then you need to replace the drive
some have replaced with flash drives

I found this. *Plug the Creative Zen in to the charger and plug it in the wall. *Press in the Play/Pause (same button) and hold it in. *Insert a paper clip in to the pin hole on the left side of player, near the bottom. *Hold the needle or paper clip in for 4 seconds and let go. *Keep holding down the Play/Pause botton. What I did was clean up disk. Then Reboot.

hard disk is bad.
can you format?

1. Detach the Zen player from your PC , and ensure that the Zen Sleek is turned off.

2. Connect the power supply to the player.
3. Hold down the Play/Pause button while inserting a paper clip into the Reset hole
underneath your player, beside the data/power connector. Keep on holding the
Play/Pause button while you release the Reset button. The Rescue Mode screen will
then appear.
4. After the recovery mode has started, release the Play/Pause button

It will display the following options.
Clean Up Scans the player and removes invalid links from its music library.
Does not affect music files themselves.
Format (All) Caution! Erases all content!
Save a copy of your player's content before formatting.
Reload OS/ Firmware Caution! Erases your player's firmware.
DO NOT select the Reload Firmware option unless you have access to a PC and you have downloaded the necessary firmware to install.
Reboot Reboots the device.

I had the same problem, After googling for a few minutes I found the reset procedure for this player.

1. Turn it on.
2. Eject any disk you have in there and close the tray.
3. Hold down the "STOP" button on the player (not remote) until the green light flashes red and the system reboots.
4. Insert disk and enjoy.

This worked for me... mileage may vary.
