A master reset returns the SYNC™ 3 system to the factory settings.
Before you Start
Press Settings in the Feature bar at the bottom of the screen.
Press the General icon (you may have to swipe to the next screen).
Press the Scroll bar or swipe vertically until you see Master Reset. Press Master Reset.
A message confirming that all system settings will be erased and reset to factory defaults will appear. Press Continue.
A “Resetting to factory defaults” message will appear, the system will turn off and the screen will go blank. It may take a few minutes for the system to reset and resume normal operation.
Things to do after a master reset
Once you’ve performed a master reset, you’ll need to pair your phone and download your phonebook contacts.
If you experience problems with phone pairing after you install the update, try performing a “clean” pairing. First, delete SYNCTM from your phone’s list of paired Bluetooth® devices. Then pair your phone as you would normally.
