2019 steering wheel controls inop

[Twiglett89]

I've got a 2019 custom which is set up as a roadside assistance van.
In the last week a few issues have appeared.
Firstly the audio control buttons on the steering wheel have stopped working ( cruise and display work fine)
The reverse camera failed to activate this morning,
the pdc tone has changed,
the radio reception has absolutely disappeared so DAB is useless and FM very rarely picks up a strong enough signal.
Every so often the media display changes colour and the radio presets all disappear.
All in all its getting pretty annoying as I spend a large portion of my day driving to assist customers and I have resorted to using my phone for music which is using all of my mobile data.

Has anybody come across any or all of these issues and managed to resolve them?
Cheers
