I held off loading kitkat until I thought it was safe. I guess I was wrong. Before the KitKat update I had no issues with my bluetooth connectivity between my DNA and my 2009 Ford Fusion Sync bluetooth system. When I started the car the phone and system would automaticly connet. Now I have to go into setting on my phone and connect manualy every time. I have no other BT devices connected to the phone. Any help would be great.
