In the navigraph hub it appears my pmdg 737 has the latest nav data however, when using fmc on aircraft the error message 'nav data out of date; appears. can anyone help ?
Hi…,
Welcome.
For which operating system, simulator and PMDG 737. Check you have the latest PMDG version.
Cheers
Ian
Hi,
Windows, MSFS 2020 and yes the aircraft is up to date
I shall assume 737-800 V 3.00.112
Try updating NavData using EFB
If still a problem, please post the same screenshots using Guide to posting Screenshots
