While this product does everything it says...I get too much interference when playing music from the phone. Also if you are on long journey it is necessary to change frequencies often to get a clear connection. As this is the main reason I bought this unit I have marked it low.
I know these are not original or top quality but I expect them to work more than a few times. That is exactly what happened...stopped working a couple of days later from first use. Waste of time and money.
