Unfortunately the maps do not update OTA. I suspect the screen is misleading (poor translation again?) and they never will due to cost of 4G across fleet to do so. Be glad to be wrong of courseDaft question and sorry if it's been asked...
It states that the installed map for the county you are in will update over the air... And that you do not need to use the usb etc unless you want to change maps.
Does it not update the UK map OTA.?
As above, I am sorted but with maps being so old (2020.3) I will probably still mainly use Waze!
