This is system details.
No real video of what happens.
But what has been happening is In later part of longer journey say 10-15 miles journey it just goes black screen and shuts down.
It then reboots and is sometimes fine but yesterday when rebooted it had no touchscreen response.
a hard reset didn’t fix it but it corrected itself after shutting car down, key out and then restarting.
Today I was sitting outside a shop engine off listening to radio when radio switched off but screen remained on no touch screen.
Again after key out shut down was fine.
All other times works ok other than gesture control was a bit hit or miss so I turned it off in settings.
