The one I got worked, but there was some extra delay of a second or two, and it did not play well with the built-in Bluetooth. If it had been my car, no big deal, but it was my wife's, and she would not just have her phone forget the car's Bluetooth (although the internal implementation is one of those really annoying ones that autoplays the last music source every time you start the car).
