Q: my ipod touch wont sync to itunes

Since you did not state the current status of the the iPod  all I can suggest is:

'

Try:

- iOS: Not responding or does not turn on

- Also try DFU mode after try recovery mode

- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.

- Try on another computer          

- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.
