Hello,
I am getting 'ARPT NAV NOT AVAIL (NAVIGRAPH)' error when I try to set BTV even though I have Navigraph subscription and it is not showing the airport thus unable to select BTV and see the airport map during taxi to gate. I have tried this on couple of airports, one of them is Munich (EDDM) but no luck. I can see the airport map during taxi to runway before take off, but not for landing.
