This hands-free mobile companion allow you to carry out a safer conversation while driving. The innovative cable connects
your cell phone to your car stereo's AUX in port (3.5mm jack). Press the button to enable the built-in microphone, and the Hotline adapter does the rest. You don't need a fancy stereo with Bluetooth to enjoy the benefits of hands-free calling. As long as your phone and stereo have 3.5mm jacks (1/8"), you are good to go!
