Mine worked on day 2. But I decided to turn it off. The problem with it is that I need bluetooth to connect when I start the car, but it won't because I am still at home. And bluetooth only come on after I am about a block away. For my car, if it does not detect bluetooth connect at startup, it won't auto reconnect. I got tired of pushing the connect button every time I leave the house.
And the other thing is that when I got home and if I am in the middle of a song or part of audio book I want to finish... it won't let me because it disconnected my bluetooth!
