Mastering the SYNC 4 can be a difficult and time consuming task. Fortunately, there are several options available to help make it easier. One of the most effective ways to reset your SYNC 4 is by performing a master reset. A master reset clears all user settings and data stored on your device, effectively restoring it back to its original factory state. To perform this process you will need access to the System Preferences menu in your vehicle’s infotainment system. From here you can select ‘Reset All Settings’ which will begin the process of clearing all user data from the device including Bluetooth connections, app preferences and more. Once complete, your SYNC 4 should be ready for use just as if it was brand new out of the box!
