Updating AIRAC in the PMDG 700

I have just re-installed the PMDG 737-700. After downloading my first Simbrief flightpan, the FMS says “NAV DATA OUT OF DATE”.
“AIRAC-2204APR21MAY19/22”

How do I fix this?

Hi Claus,

Download and install latest Navigraph Navdata Center.

Select Install for PMDG-737-700

Cheers
Ian
