HOW DO I RESET MY IPOD NANO A1320 - Philips GoGear SA3245/37 Digital Media Player

iTunes limits access to the files and PC. Try Winamp. It is more universal.

When you connect iPod nano to computer with USB cable, iTunes will launch automatically and recognize your iPod. You can create a new playlist which contains only the music you need, and then sync it to your iPod. By doing this, you can remove the unwanted music from iPod.

1. Click the iPod nano icon at the upper left corner.
2. Choose Music in the left sidebar.
3. Check Sync Music choose Selected playlists, artists, albums and genres.
4. Select the playlist which only contains the songs you need. Then click Sync.

Plug the iPod USB cable into the bottom of your iPod Nano. Plug the other end of the USB cable into a free USB port on your Mac or PC computer. Open the iTunes program by using the Dock on a Mac or the Start menu on a PC.

Select your iPod Nano from the "Devices" list in the main iTunes window. Click on the "Sync" button to make a connection between your computer and your iPod Nano.

Click on the "Eject" symbol once the syncing process is complete. Remove your iPod Nano from the USB cable. The iPod's lock code will now be reset and you will be able to access all features again.

Navigate to the "Screen Lock" option in the iPod menu to lock your iPod's screen again. Since your iPod's lock code was just reset, you will be prompted to select a new four-digit code.
I hope this will help you...
