Try to restart your item. If that does not work hold the OFF or restart botton. If neither of those work please let me know and i will make research. Email me at [email protected]

Please check teh format of teh songs downloaded, they might not be supported by teh Moto Player (*.WMA, *.RM..etc.)

it's probaly not formated right

I FOUND THE PROBLEM! You need a CoreMicro Micro SD Adapter and the USB that goes with it. Mine said it was right-protected until a person on a website told me to move a white switch upwards on the adapter. Holding the Adapter facing you, make sure the switch on the left side is moved upwards. Put it in the USB port, and then into the computer jack. Go to WMP (windows media player) and go to your library. Right-click any song and click the "go to file location" button. That way you are at the actual file location and not a link to it for playing. You see a list of all the songs you have at the raw source. Make a folder and name it "Music". Drag the songs you want on your phone into the folder. They will disappear from the menu into the folder but not from the computer so you still have the music files on your computer. With the Music file in view, right-click and go to the "Send to" button and click on the "Removable Storage" button (or something that looks similar but the same words). A loading screen should pop up and start loading the files. You are done! Remove the USB and the Adapter, put the memory card in and charge er' up! It worked for me and i hope it works for you. Thanks.

Make sure your headphones are working properly by testing with your computer headphone jack.

Is the headphone port on the Nano loose?

Connect the Nano to your iPod dock and see if you can head audio through the docks headphone jack.

If the headphones work, and you can get audio out of the dock headphone port, then there is a problem with your Nanos headphone jack.

Philips hifi systems only support flash memory sticks or MP3 players which show up as flash memory sticks.

SA5125 is not compatible

you cant expect all mp3 players to play as many songs as u wnt. each mp3 player has a limit of memory card that needs to be attached. see whats the maximum memory your mp3 player can support. and also see if you can locate all the songs when the SD card is connected to your computer
