You don't update via Zune. Zune is for WP7 devices.

WP8 updates over Over The Air (OTA). It's preferred if you have WiFi but if you have enough data you can do it it over mobile data.

Go to Settings -> Phone update

If you have WP Developers Preview and you cannot update then you will need Nokia Software Recovery Tool.
