Navigator proposes (to the one that discovered the hidden menu ;-) ) : Mute/Unmute.
Alert Only: Mute TTS/announcements but play alerts like:
Waze proposes : Mute/Alert Only/Unmute
I would suggest you a 4th mode : Quiet.
Mute: Just mute all TTS/annoncements/alerts
Alert Only: Mute TTS/announcements but play alerts like:
- Speed camera
- Speed limit reached
- Recalculating route (due to the user not following the computed route)
- Recalculating route (due to traffic ahead)
Verbose: As your Unmute mode now.
Thank you.
