I believe that the RER and the RHR radios have the Uconnect built into the radio. All other radios require a separate Uconnect module to have the hands free option. You will need the High Speed bus radio in your truck.
You will need to install a separate microphone with any radio you add. It will need to be wired to the RER or RHR radios, or for the other radios, to the separate Uconnect module.
If you get the nav radio, the RER will need a separate GPS antenna install for it, The RHR has one input for both the Sirius and GPS antennas. I also believe that beginning in 2011, the roof antenna is both the Sirius and GPS antenna.
