play music over Bluetooth through my device without allowing voice from google maps to talk over it

[Steve Rogers 57]

I am an Uber driver. I want to play music through Pandora or any other app over my phone through my car's Bluetooth, but the google maps plays voice over the music. I went into settings in Maps and unchecked play voice over music and now it still stops the music but is silent while the directions would be talking.
