I have my Blackberry Curve synced up with Ford Sync. The Sync system has a directions feature that requires downloading directions from the phone to the car. It was working great until I did the Verizon update (*228). Since that time, the downloading from the Blackberry to the Sync system hangs up and never completes. Curiously, I was half-way across the state and tried it and the Sync directions worked fine. Any suggestions?
