The listing, Jupiter Jack Hands Free Speaker For Cell Phones has ended.
This has previously been used. Comes with 6 different adapters & the Jupiter Jack adapter. I took this below from another site to give an idea what it's all about.
An easy to use device that turns your car radio into a hands free speaker phone. Simply plug device into your cell phone's headset jack and tune your car radio to 99.3 FM and start talking hands free. It's that simple! Features a built in microphone that transmits your voice clearly while you hear your caller's voice clearly through your car's speakers. Using a cell phone without a hands free device may not be safe and is illegal in many states. Now you'll enjoy clear robust sound that only your car speaker can provide allowing you to conveniently talk and drive at the same time.Works with: AT&T, Verizon, Sprint, T-Mobile, Blackberry, iPhone, Nokia, Motorola, Samsung, Sony-Ericsson, LG, Nextel, Sanyo, Kyocera and all other cell phones* Adapters and battery included* Works with any cell phone with a headphone jack. Some phones may require an adapter, the most common of which are included in this package. For those rare cases where the enclosed adapters do not fit your cell phone, we will mail the appropriate adapter to your home for just a small processing fee.( Walgreens site )
