i have subscribed to navigraph and even download the FMS data manager.
it says PMDG all product has been updated but for some reason, my 737-800NGXu BW whenever i enter the FMC it says NAVdata out of date.
the last AIRAC was from 2017 February. again i have watched youtube but it did not help, tried to find something in google but different product came up instead.
FYI, im using P3Dv5 and PMDG operation center has updated it to the latest version.
