You have to buy the uconnect kit to add to your truck. I is a option from the factory. The factory unit has a mic. in the rear view mirror, the add on kit has a mic that you have to place. I don't think the add on kit uses the radio buttons, I maybe wrong. It is a great option, has easy access to your phone book, and pretty good voice recognition.
