Sync 3.4 to 4 Possible?? Hardware v. Software
Hey yall...I was thinking about getting an aftermarket head unit....BUT then I saw that Sync 4 is in the newer Fords ( 20+, I have a 19). Does anyone know if you can just have the Sync updated at the dealer to Sync 4 system software or would it have to be whole new unit hardware??? It needs to...- deactivatedacct
