This hands free kit works perfectly well. It has a beautiful copper color and a blue LED illuminates when it is connected. (Must be continuously connected to work, the Mini USB cable - USB, audio cable is included). On the receiver by pressing PAIR 6s on the play-pause button, the LED flashes blue-red, the button is released, the phone detects it as: bluetoothcar. To pair a second apparatus, the first disconnect bluetooth. The procedure is the same with the second and reconnects Bluetooth first, and the two are connected. You plug the jack to the car audio system (car radio or bluetooth speaker for me). At each start, the phone is automatically recognized. We take a call by pressing the play button, the microphone works well. We hear our interlocutor in the speakers of the car or enclosure connected 3.5mm. Placing the receiver closest to the driver through the pellet stuck to the dashboard or elsewhere. it works better than the handsfree system in my pregnant! This receiver also allows you to stream music from your phone on your car radio if it is not bluetooth ... We advance a track or we go back by pressing the buttons on the sides. They also provide a lot of support lower or raise the volume. The instructions are in English but understandable due to the drawings. Good product, good sound towards the listener too. I took off one star because there is not the car charger in the box (not all usb socket cars). I recommend this small and rather nice!
