Hi, i have been struggling to update the Basic Sync system in my 2010 Edge LTD to the 4.4, with no success. 
 Before continuing, how can i check what version is installed? 
Officially, according to Ford, last update was to 3.1 in 2011.  Dont know if that is accurate though (vehicle is new to me) 
 Is there a way to check what is installed? 
BTW no VHR in my vehicle 
thanks!
