Here’s how to pair your phone:
Start your vehicle, and power on your Galaxy S5.
Enable your phone’s Bluetooth® feature:48
On your vehicle’s SYNC 3 touchscreen, press Add Device.
(If you’ve already paired a phone, SYNC displays the name of that device. If your screen asks you to connect a phone, make sure your Galaxy S5 Bluetooth is turned on.)
Go back to your phone’s Bluetooth settings, and scan for devices.
Both your phone and SYNC 3 touchscreen should now display a six-digit PIN.
