If I’m playing music through Apple Music connected with Waze playing through the car’s Bluetooth: Before beginning navigation, volume for the song begins at 100% of what the phone volume is set to, spoken navigation directions decreases volume of song to give 50/50 blend of music and directions at 100% total volume, and then PROBLEM - music volume increases after directions to ~85% total volume.

My car speakers don’t get loud so I need the phone and car volume at max, and with Waze I cannot get the best experience.
