How to ensure the Navigation volume overrides the other audio?

I don't think you can mute the Audio, but you can turn up the Nav voice volume

 

Have the same question. Ideally, I would like the audio from other source to temporarily mute when the navigation lady speaks (I don't care whether the other sources misses some part due to this or continues from where it left off). If that is not possible, I would like to learn how to make the navigation lady shout. If you folks have figured it out, I would appreciate your input.

 

I went the opposite way. I muted my navigation voice and just rely on the screen and HUD directions. Tired of being interrupted by the voice when I was on the phone.

 

Turned the nav voice off first day of driving. I never use it anyway. Google maps for me...

 

How did you turn it off? I keep turning the map voice off, and deleted all destinations, but the voice and a random map keep coming back on the next time I drive. Also, the type of route and route changes are not saved. I'd like to disconnect the whole thing.

 

With UK cars the Sat Nav mute button is (from memory) second from the bottom on the right hand side of the map. I think this also mutes any speed limit information. The Sat Nav volume can be adjusted up and down whenever the Sat Nav speaks by pressing the volume buttons.
