If you experience problems with SYNC® with MyFord Touch®, you can perform a master reset. This process erases all stored data, such as call history, text message information, and previously paired phones, and restores your system to factory settings.27
There are a few things you should do before starting step 1:
Using your system’s touch screen, touch Settings, then touch System.
Navigate to the second page of the System menu, then touch Master Reset.
When SYNC prompts you, touch “Yes” to continue.
“Performing scheduled system maintenance…” appears on the touch screen for several minutes.
The home screen reappears. The master reset is now complete.
