You get additional functionality besides just a prettier interface. With the G3000, you get much more in the small touch menus. I can’t remember if the G3X offers North Up tracking, but the 1000 and 3000 both do. To me, the nicest thing about the G3000 mod is the addition of Relative Terrain in the MFD. Any terrain higher than the plane or less than 100’ below is depicted in bright red. That feature saved my flight not too long ago flying into Juneau in some really crappy weather.
