How do I make my MG4 ev stop shouting at me!?

[Tara Jane]

I plug my phone in for the car play GPS, so when it speaks the directions, it’s SO LOUD!!!! I have turned the volume down on the phone, on the screen thing, every possible place I can think of… still no luck!!
What am I missing!?
Is there only one level?

Top left of screen, pull down and that brings up more settings

When a direction is being spoken, tap down on the right hand joystick to lower the volume.
