Recommended Posts

I used a USB stick and the update took 30 min with one restart.  I waited until it indicated

it was safe to remove USB device.

usb has to be formatted as fat32, correct?


According to the Ford Owners site under USB drive installation instructions and clicking on either windows or mac: Fat 32 for

SYNC versions previous than SYNC 3.  So it would be exFat.  Click on exFat for instructions.  To double check I googled how to format USB update 

for SYNC 3 and it came up with exFat.
