This unit is almost impossible to install even after spending many hours to find out you need to purchase an adapter cable for your car/truck. The receiver button broke within a week. I had to buy a new $300 cell phone because it would not pair with my two month old phone. Sound quality above 30 mph is horrible, everyone is saying I sound over-digitized or in a tube and can't understand me. What a waste of time, huge amount of money and taking my truck apart four times! Run Forest...Run from the Parrot garbage!
