Hi Cooper, I can’t find where I need to be in Plane Maker. I’ve drilled down through the files in Plane Maker and tried to “Open” the x-aviation G5 172, but I can’t get any to open in plane maker and I can’t find anything called Systems. Sorry for being a newb but I am. I’ve looked through the G5 documentation but I can’t find anything that addresses how to get the GPS DTK setting changed. Working in MacOS, thank you for any help.
