This hands-free kit is well designed. Distance correct cables and easy installation. The connection is easy and once set there nothing more to do for the phone to reconnect. This is also what could cost him a star, because if you forget to switch the radio on the "auxiliary" mode, you can miss calls while driving because you do not necessarily see the light change from blue red. At the same time it's safer than having the phone ear, and this kit can not adapt himself to all radio to enable automatic switching on the auxiliary mode. So I gave 5 stars as it can adapt to all self positions, and after the selection, or listening to music from his phone or switch to another audio source and in this case we can not answer the phone the kit without manually switch back to the "auxiliary" mode of his car radio. At least not echo or feedback and communication is established is really correct, no question of risking an accident with his phone in hand! more we gain in comfort, so do not hesitate to equip ...
