From my post on Zumoforums about this topic:
From the "Where To?" and "View Map" screen I have Volume and Tools.
I find nothing under Tools/Settings - not System or Navigation - that would seem to help.
If I click Volume I see a Mute option and a Mixer button.
Under Mixer I see Master, Navigation, and Media buttons with a % for each.
Clicking each allows me to select a percentage.
For Master and Navigation there is also a Mute checkbox.
Muting Navigation leaves the 'beeps' when I touch the screen, but I get no directions (e.g. Please drive to highlighted route.)
Muting Master appears to kill all sound, certainly the 'beeps' go away, but I don't seem to get any navigation either.
Maybe tomorrow I can check to see whether Master Mute actually stops the Sena partner communication from cutting out. And maybe confirm a total blackout of noise
