I tried to access the Functions on the MFD in mine last night - no luck !
As mentioned, mine DOES have the larger MFD (with Bluetooth). Has the Red writing, not the LATEST facelift car that has White writing on the display.
I tried the < and > buttons that are on the right side steering wheel controls. Did nothing to that screen.
Also tried pressing other buttons around my dash and on the steering wheel

made no difference.
There is a toggle switch on the right side stalk that allows me to scroll through different information, ie: journey mpg, miles til empty, set a maximum speed limit, temperature, time etc - but this is different to the extra options we are trying to get to here ??
