After disconnecting the battery in my 2019 LDV T60 everything is now in Chinese

This is a curly one isn’t it? You stand a decent chance of returning the info screen back into English, only if it’s already in English so you can drill down into the menus in the first place. You might be able to flick through the menus until you find the word 'English' (start in Settings if you can decipher even that much). Perhaps the owner’s manual gives some insight into how the language is set.

But, honestly, the quicker way is likely to be to take the vehicle to an LDV dealer and have somebody familiar with the menu system sort it out for you.

It’s tempting to think that this might happen every time you change or disconnect a battery, but who knows? Equally, it could be a glitch within the car’s body computer that controls the dashboard and many other functions in a modern car.
