Although the second generation iPod Nano (also known as 2G) uses a four-digit pass code that prevents unauthorized access to your iPod by locking the screen, you can also unlock the device by plugging it into your computer's USB 2.0 port.
When the 2G iPod Nano is connected to the computer it is synchronized, and automatically unlocks the screen according to the official Apple site.
In order to successfully unlock the Nano it must be plugged into the primary computer used for synchronizing content.

Click "Start," "All Programs" and "iTunes" on your PC's desktop, or click "iTunes" on the Macintosh's desktop dock.
Plug the iPod Nano's cable into the docking port on the iPod Nano.
Plug the other end into the USB port on the computer to open iTunes.
Click "Controls" at the top of the iTunes' menu, and select "Eject iPod."
The iPod Nano's screen will be unlocked once it is ejected from your computer.

Sometimes your iPod fails to display in iTunes, which will keep you from being able to transfer songs from your computer to your iPod. If this happens, there are a number of steps you can take to resolve the issue.
Is it the iPod? Your iPod could fail to show in iTunes for a variety of reasons and this issue can be resolved by something as simple as rebooting your iPod. To reboot your iPod, first lay it on a flat surface. Using your thumb and index finger, press the play and menu button at the same time. If done correctly, your iPod screen will go blank and then you'll see the Apple logo. Is it the USB cable? Your iPod could fail to show in iTunes if you are using a defective USB cable. Try connecting your iPod to another computer that has iTunes installed using the same USB cable. If iPod again fails to show in iTunes, replace the USB cable. Is it my computer? One of the most common reasons your iPod doesn't show in iTunes is because your computer doesn't recognize your iPod is connected. Troubleshooting your computer/iPod connection Disconnect your iPod from the computer and reconnect. If your iPod still doesn't appear in iTunes, disconnect your iPod and reboot your machine. Once your computer has restarted, reconnect the iPod. Is it iTunes? Your iPod could be fail to display in iTunes if there is a issue with your iTunes program. If there is a problem with iTunes you can try updating the software to the most recent version. If that doesn't resolve your problem, re-install iTunes. b> http://www.itunes.com/ b> http://www.apple.com/support b> iPod Won't Connect to iTunes b> Apple's iTunes software contains mechanisms specially designed to sync with your iPod, allowing you to transfer music, videos and other media from your computer. If you find that iTunes does not recognize or allow you to access your iPod, then you cannot perform some of the device's most fundamental functions. Fortunately you can often resolve this problem without expensive maintenance, simply by doing a bit of troubleshooting and determining the cause of your connectivity problem.

Try resetting your iPod. Apple recommends this as a first step in troubleshooting an iPod not appearing in iTunes, since a quick reset will often restore functionality. If you use a click wheel iPod, hold down the "Menu" and center buttons until the Apple logo appears on your screen. For the iPod Touch, hold your "Home" button and "Sleep" button simultaneously until the Apple logo appears. Charge your iPod battery. If your battery has absolutely no power left, your iPod will often remain unresponsive even when plugged into iTunes. Try charging for three to four hours and then try connecting again. Plug your iPod into your computer using a different USB port. Sometimes a failed connection can mean you have a faulty USB port, so try plugging your USB cable into a different port and see if the iPod appears in iTunes. Verify that you have the latest version of iTunes. Visit the iTunes page Apple.com and check to see the latest version available. If you do not know which version currently runs on your computer, click "About iTunes." For Mac users, this option will appear under 'iTunes" on your menu bar. For Windows users, the option will appear under "Help" on your menu bar. Download the latest version of iTunes if necessary. Reconfigure your iPod service. If running iTunes on a Windows computer, click "Start > My Computer > Manage," and select "Services and Applications." Under "Services," select "iPod Service" and click "Stop." Leave the window open and connect your iPod to your computer. When your iPod shows up on your computer, click "Start." Reinstall iTunes. If simply updating iTunes does not work, you may have defective software. Try removing the program from your computer and completely and reinstalling it.

it will not read from an ipod and we had the same problem. We plugged in a regular usb to clear and then it went away. it will play music from a usb but not a ipod.

1. Try a 'Restore'. Connect your iPod with the cable that came with it to the USB port on your computer. In iTunes, click and (Restore). 2. It's possible that the hard drive is dying. Google "iPod repairs" in your country and you should be able to find someone who can fix it. The usually have a self diagnosis on line so will get an idea of the cost before you begin

You might need a new USB cord. Try launching iTunes before connecting the iPod, and using a different USB port. If that doesn't work, try a different cord ( maybe borrow one )

uninstall service pack 3 and ignore it when it asks you to re install it. go to add remove programs and uninstall it. obviously it worked befor. that is the solution. you dont need sp3 anyway.

according to the apple website here is some help with the solution.
this is taken straight from apple.

When I plug my ipod into my computer, it doesn't show up anywhere. Neither in "My Computer" or itunes. I'm running Windows XP Professional. I've tried resetting and forcing it to disk mode, reinstalling itunes, changed USB ports, and all the other possible solutions offered by the help web site. It was suggested that I take it to an Apple store for repair. It still plays music and videos that are downloaded on it, it just won't sync up with itunes.I have more music and videos that I wish to install on it.

Hey, watch this tutorial and try the things it suggest.

Id highly recommend, restarting, and returning the device into the original state.

All this is covered in the video here:

http://www.apple.com/support/ipod/tutorials/troubleshooting.html

You can also try reinitializeing your usb ports from the device manager by uninstalling them and then restarting the pc to reinstall them.

If that doesnt help contact the appel support.

Try checking for ipod for any corrupted files. If you use P2P software to "pirate" music, try deleting those files. Also try a different usb port, and if you are using a hub, plug directly into the computer.....which Mac do you have btw?



Hope this helps.
