The car can connect to and remember multiple phones, but it can only be actively connected to one phone at a time.
If you want to switch the Bluetooth connection to a new device, you need to pair it with the car first. You can do this in settings.
Before trying to switch to a different paired device, make sure that Bluetooth is enabled on the device you want to switch to.
Press the car symbol in the bottom bar and go to Settings.
Go to .
Press the name of the phone you want to connect to.
If the connection is successful, the phone's name moves to the top of the saved devices list.
If you can't see the device you want to switch to in the saved devices list, try pairing it with the car again.
