Cant transfer music or charge it

Charge an iPod Nano Without a Charger
If you've misplaced or broken the charger that came with your iPod Nano, you might think you need to purchase a new one in order to continue using your Mp3 player.
However, there is a way that you can continue enjoying your iPod without having to purchase a new charger.
As long as you have a USB cord and a computer, you can charge your iPod without having the charger.

Locate the USB cord that came with your iPod Nano package.
It is the same cord that you use in order to sync or transfer music.
Plug the small end into your iPod Nano.

Plug the other, larger end into your computer's USB port.
Choose "Do Nothing" when your computer presents the dialogue box to let you choose what to do with the hardware or USB connection.
Leave your Nano plugged into your computer for at least 4 hours to charge.
Unplug your iPod Nano when charging is complete.
Charge an iPod Without the Charger
Many iPod owners purchase a charging unit that plugs into a standard wall outlet to recharge the iPod's battery.
However, the iPod wall charger is not included with new purchases, so consumers must either purchase a separate charger or find a way to charge their iPod using other means.
Here's a simple method to charge your iPod using your computer.

Plug the iPod USB cable into the bottom of your iPod.
Plug the other end of the iPod USB cable into a free USB port on your Mac or PC computer.

Open the iTunes program by clicking on the icon in the Dock on a Mac or using the Start menu on a PC.
Click on the name of your iPod under the "Devices" heading in the main iTunes window.
Click on the "Sync" button to synchronize your iPod with your computer data.
While the iPod is syncing, the power from the USB port on your computer will charge your iPod's battery.

Unplug your iPod from the computer once the battery is fully charged.

If you have any other questions, feel free to email me.

if its mini usb then you can get that cord just about anywhere if its a custom cable then you'll have to goto the rca website and order one from them

sometimes you need a memory card to sync or download music to phones... hope this helped

this might work you might have to try to plug it in to a different usb an see if the computer will pick it up

Down load the firmware on Sansa's website. I have a Sansa 250R and it wouldn't work with the new replacement usb (Griffin) cord I bought at Best Buy. So I bought a Sansa Fuze and the cord that came with it worked on the E250R. Huh? Yeah, go figure...and oh, that replacement Griffin usb cord I bought worked fine with the new Fuze. I came real close to buying a new battery for the E250R but instead invested that money in the Fuze.

hi :) uhmm, try to press the menu button and the center button at the same time. this happened to first ipod, a nano also, and it worked. hope this helps :) and i know how you feel emily , teehee :)

i had the same problem with mine and my computer didn't detected it so try plugging it in and out a few time it might work.but if that doesn't work go on settings and change the usb setting

This may not be any help, but I had the same problem with my MP3 player and it was the cable that was buggered. I bought a new one & all is good again. The old cable can still be used for charging, but not for data transfer. Don't know why.
