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.

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
