It is very important accessary for safe driving! For a motor driver this is a unmissable item. You can make phone calls, enjoy the radio, or you can hear the GPS audio navigation. With the application you can compare with almost every cellular phone. Easy to navigate with motorcycle gloves also, because the buttons big enough. The design is modern and futuristic, and easy to use because its outside the helmet, only the two little and very good headsets are inside. I recommend this for every motorcycle driver.
