I have a 2009 Ford Edge with navigation and Sync. 
  
This morning my battery was dead, completely dead.  My daughter jump started me and I made it to work.  Everything seems to be fine now, battery is holding a charge. 
  
Except:  Sync is seemingly dead.  Navigation and radio work fine.  My presets on the radio were not lost.  But sync is dead. 
  
When I press the Media button a message at the bottom of the screen says, "Connection error - Contact Dealer."  The instructions in the user manual for Sync say to do a "Master Reset" I press the "Phone" button and follow instructions.  When I press the Phone button nothing happens.  Nada.  I believe that Sync might be really dead. 
  
Is there a master reset button on the Sync itself?  Or could there be a fuse just for the Sync that I should check?  I'd prefer not to take it to the dealer and arrange carpool, etc. 
  
Your help is appreciated.
