I checked my owner.ford.com link, it said I had an update available "A software update is available.
Your SYNC system will be updated to SYNC3 v3.4.20136". I checked the version on the truck, and it says Sync V3.3. So I downloaded the new version to a USB drive, went out and put it in the truck. The screen said it was updating Sync. After 20 mins or so I came back and it said it was complete, and that the new version would take affect next time I started the truck. So, I started it. It still says V3.3. Shut off the truck let it go to sleep, and then started it back up again. Still V3.3. What am I doing wrong? How do I know if it actually updated anything?
