It works the same way it does on a real G1000, by pushing the FPL button and then using the large and small FMS knobs to enter the waypoints. Of course it's tricky to manipulate the knobs using the touch screen, maybe intentionally so that you'll buy the expensive hardware bezel
But other than that it works exactly like a real G1000 as far as I can tell.
Also note that you have to show the bezel on the touch screen to access the knobs and buttons. If you only see the G1000 display itself and not any of the knobs or buttons then you need to tap in the upper left corner to show the bezel. Also you can tap in the upper-right corner to access settings and setup things like your default airport, which will affect which airports you see when you use the NRST function, etc.
Hope that helps. Otherwise if you can provide more specific details maybe I can figure out why it's not working for you.[/QUOT
Thank you so much I finally got that going ! But now the default setting is somewhere in China. How can I change my home airport to the US, so I can follow the tutorials offered online?
Thank you in advance
