Simply connect your iPod to your Mac/PC with your connector. Make sure you have iTunes already installed. After you connect the iPod, it should automatically sync your music, videos, movies, etc. To iTunes. If you need additional help, go to Apple's website at apple.com
if your asking TO itunes FROM an iPod, it'll only transfer songs that you bought from itunes, not CD ripped songs or songs downloaded from anywhere else. (I found out the hard way :()
