Newer models of the iPhone feature the A2DP stereo Bluetooth profile, which allows the smartphone to stream music and other audio through a Bluetooth head unit and speakers. Pioneer makes several car stereos with A2DP Bluetooth, so if you’ve got an iPhone and a compatible car stereo, you can play your music through the car’s speakers without even connecting a 1/8-inch plug. The initial setup is somewhat tedious, but after it’s done your phone and your car stereo should communicate with each other automatically. Tips Writer Bio
