I listen to my iphone a fair bit thorugh my car stero with an auxiliary cable. However, when a call comes in, it connects to my car stero via bluetooth. So far so good.

However, when the call ends, the audio source for whatever I was listening to (music, pandora etc.) switches to bluetooth, and I cannot hear the audio anymore.

Are there any apps that can "hide" the bluetooth source from all apps other than the phone?

I read about the bluetooth profile selector, but it does not work with the latest iOS. I am currently using the bluetooth mono sbsettings toggle, but it does not work very well. Plus I would rather listen to the music via stero aux as opposed to mono bluetooth.

Any thoughts?
