How to reverse pair your phone
To use any of the phone features for SYNC® with Voice-Activated Navigation—such as making a call or using SYNC Services—you must first connect, or "pair" your Bluetooth®-enabled phone. Some smartphones use a four-digit Personal Identification Number (PIN) and cannot accept the six-digit PIN provided by SYNC. Reverse pairing allows you to pair a phone requiring a four-digit PIN.27,48,129
Enable your phone’s Bluetooth® feature and make your phone discoverable.
Press the Phone button to access the Phone Menu.
If this is the first phone to be paired, a pop-up displays. If not, touch Settings on the touchscreen.
SYNC lists any phone that has been paired. To pair another, touch Add.
SYNC prompts, "Search for SYNC on your device and enter the pass-key provided by SYNC."
When SYNC displays the six-digit pass-key, touch Find Other Devices. When SYNC has discovered your device, the name of your phone will appear. Touch its name.
SYNC prompts you to enter the pass-key, also known as a Personal Identification Number (PIN). Touch the four numbers you were given, such as 0000 or 1234, on the touchscreen that you will also enter in your phone. Then touch Enter.
When your phone displays a similar prompt to enter a PIN, type the same numbers, 0000 or 1234, and press OK or enter.
If your phone asks if you always want to accept this request, choose Yes.
Upon successful pairing, a message displays confirming the phone is connected.
Your phone is now paired. You can make this your favorite phone and download your phonebook.
Make your phone discoverable
You'll usually find Bluetooth, the wireless technology that allows your device to connect to SYNC, on your mobile device through the Main menu> Settings> Wireless and Networks> Bluetooth.
Once you access Bluetooth settings, choose discoverable or hands-free. Consult your device manual instructions for how to enable Bluetooth and make your device discoverable. You may also need to scan for devices on your mobile phone.
