I have a Bluetooth stereo in my car for streaming music. What I hate is that anytime I'm in my car and want to make a call or even use Siri it defaults to laying through the stereo. Even if I'm listen to just the radio and want to make a call or if I receive a call it wants to play over the stereo. I know I can select the iPhone from the menu on the phone itself, but I hate doing this, and I hate that the music stops. Is there a fix, a workaround, or am I missing something? I have other Bluetooth devices, mainly my Apple Watch, or I'd turn Bluetooth off when I'm not listening to it.
