why wont my ipod touch sync with itunes, and how can I fix it

Key Facts:

-I have an ipod touch (model number MC008LL)

-It's probably running the same iOS id did in the package

-It won't sync (and more importantly update to i0S5)

-It's not a failed/slow sync, the option to sync as well as all other options under "Devices" is Grayed out

-I am running iTunes 11.0.4

-the Belkin cord I am using charges the ipod, and I think it was the one I used to sync it before.
