It is a bluetooth module, but it has an aux in and a microphone jack. If you want to talk over bluetooth you need to run the mic up from the trunk. If you want the auxiliary input you need to run the cable up from the trunk as well. But out of the box, plug and play, it will play bluetooth audio from your phone without any running of any cables.
