GTN750 on 2 computers each running identical copy of X-Plane in RXP GTN 750/650 Touch Posted April 18, 2017 Hello, Thanks for the reply myanezt, but what do you mean exactly? You run two different machines, but you have 2 instances of X-Plane on machine #1 and a third instance on machine #2? I'm glad if it works for you, it would be nice though if it could also connect to the HSI (or whichever instrument) on the master machine. Do you mean that you can only use the GTN to view a moving map/terrain? You cannot use it to connect to autopilot or tune radios,transponder etc.?
