I think the video you watched was talking about Bluetooth. You have to pair your phone to your car and then it should show up in the Bluetooth section of your phone as "Ford Sync". There's not a special app, as far as I know.
Usually the procedure is to put your car into pairing mode. On every car I've ever paired a phone with there's an "add phone" or "Pair device" option in settings. If you have a touchscreen in the car it's usually a little easier to find, otherwise you'd have to do it with voice commands. Once the car is in pairing mode, open Bluetooth in settings on your phone and it should scan for devices to pair with. Ford sync should be listed. Once you tap on that, you might be asked for a security code. It should either have been already set when you entered pairing mode or it will be displayed on the phone.
This might help.
