• Check system requirements. - iPod nano (5th generation) requires the following minimum versions of Windows: either Windows XP (Service Pack 3 or later), Vista or Windows 7. If you have one of these versions of Windows, verify that Windows is fully up to date by downloading and installing software updates from Microsoft. If you have Windows XP with Windows XP Service Pack 1 or Windows XP Service Pack 2, download and install Service Pack 3 using Windows Update.
  
  
• iTunes online? - Confirm that iTunes has been downloaded and installed.
  
  
• AMDS online? - iPod nano requires Apple Mobile Device Support (AMDS), which should be automatically installed with iTunes. To verify whether it is installed, click Start > Control Panel. Open the Add or Remove Programs control panel and verify that Apple Mobile Device Support is visible in the list of currently installed programs. If it is not, remove and reinstall iTunes.

DId you install Itunes?

Without Itunes the computer does not recognize the Ipod...

If you connected your nano before you installed itunes your computer saw it as a storage device already anditunes will not see it. You must uninstall the nano from your computer by going to the hardware tab on the system properties window. click device manager on that tab and all hardware installed on your computer will be listed there. Right click on the nano and chose the uninstall option on the box that comes up. Do this with the nano not connected. After you uninstall it start itunes then connect it to the computer. Itunes will then recognize it and take you through the set up.

hiiiiiiii

I struggled with this issue for a while and finally found a post that helped me. Hold menu and the center buttons until the iPod turns off. Then, immediately hold the left and center buttons to pull up the iPod diagnostic menu. Scroll down to the option "Reset" and select it. My iPod was finally recognized by iTunes. Good luck :)

If your iPod fails to hold a charge and it's more than a year old, you may need a new battery - http://www.apple.com/support/ipod/servic...

Hope this helps.
