I use both google maps and Waze in Android Auto on my 2016 Civic EXL with navigation. The volume for Google Maps has different volumes controls for maps and music so you can set the maps to a lower level than music. It doesn't matter if I'm streaming Spotify or Pandora. When I use Waze it seems the volume for both music and Waze are the same. You can't set each of them to different levels. If your jamming music and Waze needs to speek its way to loud. Same with both my Samsung S8 + as my Samsung 9 +. Any suggestions? Thanks!
