During the week, our 321 announced we were running 10 minutes late. Is that something the driver initiates or does it automatically know how late we are against the timetable?
I've only heard messages relating to delays very early on when FCC 317s got their new systems. Never heard since, so I assume they're manually controlled and drivers simply don't use this feature now.
365s seem to have the display and audio out of sync, as if there are two separate systems in use? Maybe one system sets them up, but they definitely look like a bit of a bodge.
A 317 announcing stations in reverse is because the system wasn't reset and it triggers at the same GPS coordinates but backwards, so the announcements for that station come just after you've passed it. It would be dead easy for the software to realise this after a couple of points passed in the wrong direction and suspend itself pending driver intervention - but I guess nobody thought of that.
Edit: And from what I've just read above, it doesn't help if a driver can't control the system from every cab! It seems to me that the whole system, including the internal and cab window displays, was a very cheap and nasty buy by National Express going by how many screens are now faulty with either no LEDs working or loads of corruption and glitching.
The audio sensors can also make the volume unbearable in some carriages or far too quiet. The ancient 365s seem to have no such problems, besides often not being enabled at all.
