My wife and I both have our iPhones paired via Bluetooth with her 2018 Discovery V. It defaults to connecting to her phone as she usually uses the car. But sometimes when traveling together I manually 'switch phones' in the phone settings so my phone is connected instead. That works for calls, but the music system still sees my wife's phone for music. And I've tried several times but can't seem to find any way to switch the phone that the music system is connected to. And can that be right - that Bluetooth uses my phone for calls and my wife's for music at the same time?
