Switching between phones on Apple CarPlay is a straightforward process, but the method depends on whether your car supports wireless or only wired CarPlay. In most cases, you’ll need to manually connect the second via the car's infotainment system or by plugging it in with a USB cable. There’s no direct "hot-swap" button within the CarPlay interface itself.
The simplest way is to use voice commands. While CarPlay is active on one phone, press and hold the voice control button on your steering wheel and say, "Hey Siri, disconnect CarPlay." This will end the session for the first phone. You can then connect your second phone.
If your vehicle supports wireless CarPlay, the process involves going into your car's Bluetooth or CarPlay settings. First, ensure the first phone is disconnected. On your car's main infotainment screen, navigate to the Phone or CarPlay settings menu. Your car should show a list of previously paired devices. Select the second phone from this list to connect it. The system may take a moment to switch over.
For wired CarPlay, it's even more direct but requires physical action. Unplug the first phone's USB cable from the car and plug in the second phone. The infotainment system should automatically recognize the new device and launch CarPlay for it after a brief loading period. This is the most reliable method, as some cars can be finicky with wireless switching.
It's important to note that not all car models handle multiple phones seamlessly. Some may require you to go into the phone list on the screen and manually select a different device. Consulting your vehicle's owner's manual for specific instructions is always a good idea. The key is to ensure the first connection is fully terminated before attempting to connect the second device to avoid conflicts.

Just unplug one and plug in the other. That's what I do with my work and personal iPhones in my F-150. The screen goes blank for a second, then the new phone's CarPlay pops up. Super simple, no need to fiddle with menus while driving. Works every single time. It's the most foolproof method.

As someone who rents a lot of cars for work, I've found the method varies. In some models, like a recent , I had to tap the CarPlay icon on the home screen, which then showed a small settings gear. Tapping that revealed a list of phones to choose from. In a Chevrolet, I had to go into the "Projection" menu in settings. The lack of a standard button is a bit frustrating. Your best bet is to look for a "Phone" or "Apple CarPlay" icon on the main screen and explore its menu options.

Safety first, folks. Don't try to figure this out while the car is moving. When you're parked, go to your car's main settings menu—not the CarPlay screen. Look for a section called "," "Device Connections," or "Apple CarPlay." In there, you should see a list of paired phones. Just select the one you want to use. It might ask you to confirm the connection. This method is a surefire way to switch without any guesswork.

My wife and I share a car, and we use wireless CarPlay. The trick is that the car often automatically connects to whichever it recognizes first. To force a switch, I go to the Bluetooth settings on my iPhone that's currently connected and tell it to "Forget This Car." Then, my wife can get in, and her phone will connect instead. It's a bit of a hassle, but it works. Alternatively, turning off Bluetooth on the active phone for a minute lets the other one take over.
