What is SYNC?
SYNC is a fully integrated, optional in-car communications and entertainment system that gives drivers hands-free voice-activated control over their mobile phones and digital music players. After an initial one-time setup, SYNC automatically connects drivers’ phones and music players with the vehicle’s in-car microphone and sound system.
Sync is short for synchronization. In Windows, sync is the process of keeping two or more versions of the same file stored in different locations matched with each other. If you add, change, or delete a file in one location, Windows can add, change, or delete the same file in the other locations that you choose to sync with, whenever you choose to sync.
