Needs more control for audio alerts

I signed up for a seven day trial period. Maybe this is a good routing app but I find the constant audio tones of upcoming turns to be beyond annoying. First because everytime the tone goes off it causes any other audio I am listening to on my device to completely stop playing and is
a MAJOR distraction. Second there are far too many tones occuring. And while you can turn off the voice directions in the settings menu, there are no controls for these annoying tones.

My advice to developers, make the app interface better with other media players.
Make the tones controllable in the settings menu.
