In this case, course selection is made on the mechanical CDI, but the GDU has the navigation information from the SL 30.
Justin, can I do something like this with the 255 as well? One reason I have not added a second navigator to my aircraft is that the G3X would not allow me to show one source per G3X screen (PFD1 shows GTN, PFD2 shows 255)
