I've had this happen a couple of times in the last 6 months. You can get it to play again by chosing the format option from the settings menu. Of course, then you've lost everything you had loaded on to it. Download your music/audio books again and they will play.

You may be syncing them to the wrong file. This is odd, but try fishing around the device for any "Music" folders. Then, you should be able to cop&paste the songs there. Please rate!

the radio and mp3 uses one audio amplifier, check if you have loaded your music with mp3 songs, if not load with mp3 songs. if songs used to play and just stopped playing, then follow these steps,

i does your display show song playing, if it does then your set is fault, and if it doent and display unsuppoted, load with mp3 songs.

ii if it was playing and just stopped, than take it to a tech, who can open it and check the change-over switch, or selector of that set.

iii the problem is to very big.

press the middle button and the power button for q0 seconds

Reset the player once to make sure it isn't a temporary glitch - reset will NOT erase all of your songs.

Press the downward part of the circular ring when the word "music" is on your screen, and see if it will scroll doen to FM; if the word "music" does not appear, press the left side of the circular ring until the word "Music" appears on the screen

download some new songs? might just be the screen. see if you can play songs (blind navigation).

When you power on your MP3 player it will go to the FM radio. 1. Press menu.
2. Go down once and you'll be on "Mode". Press the right button to access the mode menu.
3. You either press the enter button after accessing the menu or go down to select Playback mode (I forget which one it is).

Good Luck!
