Evidently this capability is a per-plane issue. It depends on the size of the GPS in the plane's panel:
"If the panel GPS is sufficiently large to display the original screen, the popup window is never automatically toggled.Try the c172: The 2d panel GPS is too small to actually show the real screen, therefore manipulating the right knob will toggle the popup so you can see what the heck you're doing.Now load the Baron 58 instead: Here the panel GPS is large enough and shows the actual screen. Twist the right knob in the 3d panel and note the popup does not trigger automatically.So this functionality already exists, it just depends on whether the plane's panel is compatible with post-10.30 instrument sizes."
