DAB Station names small

[Nigmss]

Does anyone know how to display the station names bigger than the Location Info... I.e.

National D1 is large
Radio x - is tiny

Cheers

Is the same on every car, some people have spoken about secret menus in the infotaiment unit but I don’t know how to access it myself as I don’t want to bodge anything. (Think someone called one of them an engineers menu?)
