Why bother with a hands-free kit to hang behind a car radio when the solution is? Simple, fast to implement, compatible with the iPhone 4. French Company of the Aude, 2 year warranty, what more? It was either a premium kit for my VW 300 euros without microphone and without setting the VAG.com is this "clip" to hold on to a Bluetooth visor who returned me 46 euros given an ODR 20 euros Supertooth and shipping ZERO euro. Amazon has become a reflex for all purchases. Let's hope it continues.
