You don't need to update OS as it's been updated automatically when you update other software's........... You will notice when ever there are any updates for OS it will be the first to update than only you will be able to install any other software update's........
Yes, when ever there is OS System update it will be first on top of all other cars software, till you don't update OS it will not let you install any other updates...........
