If you spot any further issues, please do drop me a Private Message. Mind, Arriva has yet to fix their "Sapphire" 57-reg ADL Enviro400s which have the same issue - how long ago were services X21/X22 converted to Sapphire..?

The update to the displays for the Sapphire fleet were done in October 2014. This caused problems with the NSA monitors and the displays alike. A replacement update was sent to them.

The 57-reg batch didn't receive the revised update, as the problems were 'minor', but I've been told that they'll get fixed by the new year.
