Android Instruction Volume

[Daryl Saunders Qld Australia]

Using my phone in the motorbike mount with Cardo PackTalk Bold.
When a driving instruction is announced I turn the volume up, when it returns to playing my music it it at the higher volume not the volume set for music.

If I take a phone call and turn the volume up when the call ends the music is at the original volume.

It is my understanding that with Android and probably Apple the preferred volume is stored for the app. MRA seems to change a master volume.

@Daryl-Saunders-Qld-Australia is the behavior with other apps different?

I believe that this is the same with TomTom Go / Google Maps erc. Phone audio indeed has another volume level / audio channel.
