Well, ca troubleshoots, but it drives you crazy, so buy more of a CD player or radio with jack because frankly .. sound quality is awful and if your iphone is not in flight mode and if you did not first remove the antenna of your car, you risk being cut in your tracks when you will decide to find ishlag network .. In addition, the cigarette lighter cable iphone has to walk for a week but for the price, it is rather not too bad, do not invest in a device similar to more expensive, it's useless.
