I've had this adapter for around half a year now. Totally satisfied. I use it together with an additional AUX Link Bluetooth module, so it's a car audio adapter + hands free kit. I used to have Parrot Bluetooth adapter installed by the previous owner...but that combo did not allow me to stream music from my iPod and HTC via Bluetooth though...So I replaced it with the new "all in one unit".
If finally you decide to buy it I suggest you doing this at the official page AUX Car Kits, because I was comparing and they have lower prices than resellers...
