Jupiter Jack Features:

Using a cell phone without a hands free device is not safe and is illegal in some states. 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.
