If you've ever been driving your Ford and had an incoming call that you didn't want to take, you may have been frustrated by the fact that there's no way to mute the Sync system. Luckily, there is a workaround. Here's how to do it:
1. Start by putting your car into Park.
2. Next, press and hold the Phone button on your Ford's steering wheel for about five seconds.
3. Once the display changes, use the arrow keys to scroll over to the Settings menu.
4. Scroll down until you see the entry for Do Not Disturb Mode. Select it with a tap of the Enter button.
5. You'll be prompted to confirm that you want to enable Do Not Disturb Mode; select Yes when prompted and then Exit out of the Settings menu when you're done.
And that's it! With Do Not Disturb Mode enabled, any incoming calls will go straight to voicemail without even ringing through on your Sync system (though they will still show up in your recent call history).
