How do I adjust the volume of the application on an Android Auto?

[Manuel Tos]

When I use the application on my android auto, the sound of notifications and voice is always full despite the music volume being low.
I didn't find any settings in the app to adjust the volume of the application on an Android Auto?

On the application to increase the volume it is the volume + or - button of the phone which allows you to increase the sound.

You can try adjusting the volume exactly when the GPS is speaking.

Yes true when you use only the phone , but once connected on android auto , you can't adjust the volume , so iI have no choice only to use the notification channel and listen voices throught the phone and not the speakers of the car
I found on youtube that previous releases of the apps , you can adjust the volume but not on this new version that I have on my android phone
