Upgrading the radio/sync in Sable
 

I have a 2008 Sable and have the general radio, as seen below.

Is it possible to replace the radio unit with a new touch screen version of Ford's MS Sync radios? The one with navigation and everything? The buttons on the steering wheel seem to be the same for the most part so wouldn't it be plug in play to get all the buttons to work properly and all?
