Not all car radios that have USB ports support iPhone connectivity, so make sure to check your head unit’s manual first. Newer cars may have an infotainment center that supports CarPlay, which is a more advanced way to connect your iPhone to your car using a Lightning USB cable.
If your infotainment center supports CarPlay, tap or select the CarPlay option that appears on the menu after connecting your iPhone. Check your car stereo’s manual if you do not know how to set your specific car stereo to USB or iPhone mode.
