Using a cell phone without a hands free device is not safe and is illegal in some states. Jupiter Jack™ turns your car radio into a hands free device and is designed to work with ANY cell phone on ANY car FM radio.

Just plug the Jupiter Jack™ into your cell phones headphone jack, tune your radio to 99.3 FM and start talking.

Jupiter Jack™ transmits quality sounds through the speakers in your car so you hear the other person loud and clear. Now you'll enjoy the ability to safely talk and drive at the same time.
