GPS Disabled

[Pigeon]

I am having a problem with the inflight gps system being disabled and not even turn on. This seems to happen even when the PlanG software is closed. It only happens with planes i plan a route with not others. Why is that. Is there a setting or something i may have missed.

Did you turn on the avionics master? This has nothing to do with Plan-G.
