Apple updates CarPlay to allow seamless switching between two iPhones

CarPlay can now be switched between two iPhones in the same vehicle, a change that has become practical thanks to new iOS 17 features and updated car‑infotainment systems. When two drivers or passengers bring their phones into a car that supports CarPlay, the system will automatically connect to one device, but drivers can now choose which phone controls the display and functions.

The ability to swap connections is part of a broader push to make in‑car tech safer and more user‑friendly. CarPlay debuted in 2014 and has received frequent updates, but it has traditionally struggled when more than one paired iPhone is nearby. The latest iOS 17 release adds SharePlay support for CarPlay, letting passengers join the driver’s Apple Music session and add or reorder tracks from their own devices. Spotify’s Jam feature offers a similar experience for users of the streaming service. These additions give passengers a convenient way to control music without having to touch the car’s touchscreen.

Switching the active CarPlay device varies by manufacturer. Many infotainment systems let drivers set a primary phone in the Bluetooth or device‑management menu. Hyundai, for example, allows on‑the‑go switching between CarPlay and Android Auto, and the system will remember the choice for future trips. If the car defaults to a passenger’s phone, drivers can manually turn off Bluetooth or Wi‑Fi on the other iPhone, or use a wired CarPlay connection to force priority. Reddit users report mixed results with the wired method, but disabling the secondary phone’s wireless connection usually works quickly.

The new switching options reduce a common source of frustration for drivers who want to keep navigation and hands‑free calling on their own phone while letting passengers control music. As more vehicles adopt these features and iOS continues to roll out enhancements, drivers will have greater flexibility and safety when sharing a car with multiple Apple users.
