I don't have the nav. radio but I do have uconnect and I love it. It is very easy too use and for the most part so long as the windows aren't down you can hear and speak in a normal tone of voice. Depending on conditions sometimes the voice reconigtion is a little sketchy but usually on the highway w/ the windows up it works great. You have to be careful though cause you don't know how many times I've had the radio playing doing something a few feet away the bluetooth will pick up the phone and you have to run to the jeep to get it. I've used on the job site when I was using the KJ to make a cable pull. Very handy all and all.
