If that goes off, as it did on a bus I was on last week, then the NSAs stop entirely (as well as the bus disappearing off the live map)
Aye, I can understand the announcements momentarily stopping, because of loss of data access or whatever it needs. My original post was because the NSAs were working, i.e. the destinations being displayed on the screen as expected, but the volume had been turned right down.
