Ive also definitely been on a Darlington Pulsar recently that had updated Next Stop Announcements. It seemed to work quite well, with a rolling mix of cross marketing between stop screens. Audio was the new female voice used in recent Teesside updates and I think the Northumbria X21/22?

Sounds like the depot haven't bothered to update all of the vehicles if some were not working, which is a shame as the system has many benefits.

Who actually manages the system anyway?
