Add a volume slider!!

Waze plays at 50% what other media on Android Auto headunit does. There is no way to change this independently. Adding a volume slider in app would allow me to hear navigation without rupturing my ear drums.

I've seen some users complain that it's too loud for them (opposite issue). There's not going to be a setting that's good for everyone. We need independent control.

Also, my Guidance Volume setting is maxed out.
