I've been using the Reality XP GNS 550 for many years on X-plane 11 and it has always integrated well with the autopilot. Today I installed the Reality XP GTN 750 and it does not integrate with the autopilot. When I check the GTN 750 settings they are locked so I'm assuming that's why it's not working with the autopilot but I do not know how to change it. Any help would be appreciated? Thanks. Unfortunately I wasn't able to figure out how to add a picture of the GTN settings.
