I have a lovely left hand drive Caddy California...now back in the UK for a few months, but I can't seem to change the speedometer from klm to mph.

Does anybody know how to get the speedometer to work in mph? All the other settings I can change ok, but not the speedo.

You may need to plug it in to do that

It’s in the settings on a 6.1 in Units. Clear as day.
If it’s not there perhaps it’s for a reason. Odd though
