Audio and charging cable with 3.5mm jack and USB port for the Apple iPhone, iPhone, iPod well I do not have a car that I could use the cable, but I noticed a clear improvement in sound quality on my home stereo system. Warning: You must know that every time, when you receive a call, the phone is placed in the connected system. It's taking a little time with me before I realized that I receive a call and it's not my favorite song that plays !! The cable gives us a good impression and seems to be totally apple. The quality is top! The iPhone is the touch syncs directly with iTunes and the battery can be recharged works with cable.
