Introducing Jupiter Jack, the new revolutionary hands free device for your cell phone. It turns your car radio into a hands-free phone. Designed to work with any phone and car, all you do is plug in the Jupiter Jack into the place where you would normally plug in your headphone, tune your radio to 99.3 FM and start talking. Jupiter Jack transmits quality sounds through the speakers in your car so instead of hearing music, you hear the other person. Now you’ll enjoy the clear robust sound that only your car speakers can provide so you can safely talk and drive at the same time. Using a cell phone without a hands-free device is not safe and is illegal in some states. Talk and drive safely with Jupiter Jack. As featured on Discovery Channel show Pitchmen with Billy Mays and Anthony “Sully” Sullivan.
