For those who are interested, I have noted down each available customisation option on the Mk 7.5 GTI. I've only listed the top level menus and not all of the options/sub-menus as there are quite a lot, but you get the general idea. Bare in mind, some of these options are already enabled by default for the GTI. The app can configure lesser model Golfs which may not have these options on the dash display.
