Thank You
@N2STY I will give it a try. However it appears to have sorted itself out in the meantime.
It has likely to have sorted itself out, because when you close down the car completely, then the next time you boot up the car, it has automatically reset the head unit.
@N2STY suggestion, it a great "On The Move" fix for many of the faults on the info unit.
Holding down the far left "Home" button down ( for about 10 seconds ) until the info screen turns black and closes down, then release the home button.
It will then automatically reboot to the "MG" logo screen.
See this as a master reboot of the info unit if you like.
Last week, while sitting waiting to pick up our grand children from school, I noticed that the symbols that display the heater fan speed and the required temp figures, had suddenly been blanked out ?.
Hard reset of the info unit ( with the car still in READY mode ) and when it rebooted, both readings suddenly reappeared back on the display.
A glitch in the system.
It was a similar situation on the ZS EV Gen 1 info unit, where it would require a manual reboot from time to time.
The head unit in the Gen 2 has been improved a LOT over the Gen 1, but still has a few "Bug's" affecting it.
The Gen 1 system was a windows based system, but the Gen 2 system is running on the Android based system.
