how do I sync new IPOD to current computer library of music
Pretty simple. Download iTunes, plug in your iPod, and click "Sync" on the computer.
If not an iOS device, you must sync with computer, then sync with other iPod.
Start your computer, Open Itunes. connect your ipod to your computer. It will probaly make you format your Ipod. Click Sync
When you plug your ipod into your computer open itunes and check if the sync options are saying that it will auto sync them if not try to find the button that will auto sync them. : - }
You have to sync it because when you sync it go from your computer to your iPod but if you have an iPod touch you can download songs from your iPod's iTunes store.
When you plug your iPod into your computer, there is a sync option with iTunes. How it works is it puts everything on your iTunes into your iPod.
When you sync a iPod touch it backs up your iPod and it can download all the songs on your computer (if you choose that option when you go to you iPod setting in music on your computer) :)
It can sync with a maximum of five computers.
You can sync pics from your computer into your ipod by copying the pics into itunes and sync afterwards.
Usually when you connect your ipod to your computer it will sync with iTunes installed on your computer and it'd do the same for your new iPod.
Just plug the other iPod in and sync it.
