The Zumo connects to your Autocom by wire for directions and music etc.
You then, as Toad said, get the Autocom bluetooth dongle which plugs into your Super Pro. The Zumo then pairs with the Autocom dongle and also pairs with your phone.
Your phone functionality is then taken care of by the Zumo interface, which you set to send only 'phone' traffic via blurtooth to the Autocom.
A word of warning though, some phones work well with this set-up, some phones work now-and-again using this set-up and some phones just don't want to play ball. Bit of a lottery in my opinion.
