CarPlay only connects one phone

You can pair multiple iPhones to your car, but CarPlay will only project one at a time. If your car connects to the wrong phone, you'll need to manually switch.

“Though you can set up CarPlay for multiple iPhones in the same vehicle, you can only use one of them with CarPlay at a time.”

Set a preferred phone in settings

Most car infotainment systems let you choose a primary phone that gets priority when multiple iPhones are nearby. Look in your car's Bluetooth or device management menu.

Quick fixes for switching phones

Turn off Bluetooth and Wi-Fi on the other iPhone to force your car to reconnect to the right device. Some manufacturers like Hyundai let you switch on the go.

Use SharePlay for passenger control

iOS 17 added SharePlay support for CarPlay, letting passengers join the driver's Apple Music session and control the queue from their own phones without needing a subscription.

Spotify Jam offers the same feature

Spotify's Jam feature lets everyone in the car contribute to the music queue from their own phones, even without a Premium subscription.

Music control is the only workaround

SharePlay and Spotify Jam only let passengers control music. For navigation or messages, you still need to manually switch CarPlay connections using your car's infotainment system.
