This little device is awesome! I'm finally able to listen to the music I have on my phone and make calls as well. It has several different features, such as an equalizer, phone call options, etc. This is a must have if. Your stereo is not Bluetooth ready. My state just passed the Hands-Free Law, which means that if you get caught with a cell phone in your hands then you will receive a Health fine but I no longer have to worry about that!
