Hi, I bought this key to put the music and listen to it in my car, and the void is nothing that does not work ... I told myself that this is not the car radio works well with another USB key. Thin every time I buy a key it will not. Despite my internet research I have not found a solution ... Well if the answer is that my daughter gave it to me first save the cd on the computer (I recommend the last of mickael jackson) and then make the synchronization of the computer and there it works ... beautiful pink key to a girl car is great ...
