I am going around in circles, so I need some assistance. I successfully purchased and installed the GTN750 and 650 into X-plane and running on JustFlight's Arror and Warrior aircraft. These seem to be able to only fit the 750, with the 650 showing up as a window only. The GTN MOD also displayed the same on SimCoders REP for both Pipers. Good so far it seems.
So now I moved to the default C172 so I could display both 750 and 650 as a 3D panel. But when I go to the GTN plugin GTN1 it initializes as a pop out window. I can also open GTN 2 but it too is a pop out window. When I try and force the display to show as a 3D panel via the RealityXP.GTN.ini nothing shows. The default Garmin 530 and 430 remain visible. I also installed x-aviation's G500, and it seems to be working as advertised.
I saw a forum post on displaying two 750's but I only need the 750 on top of the 650. If this has already been discussed, please point me to the solution as I have been unable to find or understand what I should do next.
