This will be somewhat helpful. I cant remember where I bought it (i think Best Buy, this is the slightly less helpful part
) but it plugs into your AUX and your 12 volt (either the one on the dash or in the center console) once it is plugged in pair your devices, since you mentioned hands free the "button" will need to be mounted near your steering wheel or on the driver side pillar. I do not know how well the device works as far as the microphone goes. The audio seems great to me and it pairs in less than 2 seconds once you push the button. I am also not an audiophile so YMMV.
