device does exactly what it says brilliant little device for in your car. hands free calling with just one button push. stream music and change tracks with the buttons on the side. the only thing that let it down was the cables it came with the aux in lead was poor quality and crackled when in use and the charge power cable was only about two inch long. i was able to mount this device in my car with a few double sided sticky tabs. had to find some better cables. this is a very alternative to upgrade your car stereo system.
