How do I perform a SYNC®* 3 master reset?

Resetting the system

Before performing a master reset, try resetting the system to restore functionality that has stopped working. The system reset does not delete any data you have stored. To reset the system:

  1. Simultaneously press and hold the Seek up and the audio unit Power buttons until the screen goes black.
  2. Wait three minutes to allow the system to complete the reset.
  3. Press the audio unit Power button to switch the system on.

If the system reset does not resolve the issue, continue with a master reset.

Performing a master reset

  1. Start your vehicle. Ensure your vehicle is in park and running, not in accessory mode.
  2. Press Settings on your vehicle's SYNC screen.
  3. Choose General.
  4. Scroll down and press Master Reset. A message confirming that all system settings will be erased and reset to factory defaults will appear.
  5. 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.
