Greetings,

I have Spotify on a Android Tablet

I can trun the "Media Volume" output while playing Music on Spotify but:
If i use my Tomtom Navigation or other Navigations, the voice output uses the same Channel "Media Volume" and the Voice of the navigationsystem is to quiet. 

If the navigation app say somthing the Musik of Spotify stops and i cant nerly hear what it does say and than its continues.

The loudness of Spotify is nerly double high as the Navigationssystems

I already turned the loudness of the Navigation systems to maximum

What can i do?

Is there a way to customize the loudness of Spotify??

frendly regarts 

Bengele
