SYNC, powered by Microsoft, is the standard audio system on many Ford vehicles, including the Explorer Sport Trac. With SYNC, users can sync the stereo with a Bluetooth-enabled cellular phone, accessing not only the contact list, but text messages as well, all on the audio touch screen. Users also have the ability to use the stereo for hands-free calling while driving. Since pairing a phone to the stereo takes the user's eyes off the road, the system will not allow pairing when the vehicle is traveling at more than 3 mph.
Turn the ignition to the "On" position. The SYNC system starts automatically.
Press the "Phone" icon on the touch screen to access the phone menu.
Select "System Settings" from the phone menu.
Select "BT Device" from the settings menu.
Touch "Add Device" and select "OK." Press "OK" again when "Find Sync" appears in the display screen.
Open the Bluetooth menu on the cellular device and enter it to "Discovery Mode." A six-digit PIN will appear on the radio display when the phone is discovered.
Enter the six-digit PIN into the phone when prompted. When the display on the Explorer Sport Trac says "Connected," the two devices are paired and the cellular phone automatically syncs with the system.
