This is a new message now that January 15, 2020 has passed. It occurs when no charts have been added, and the MFD is programmed for CMAX.
This message is only addressing the MFD when charts have never been installed, and the pilot is using a different source (paper, or other device).
It is the responsibility of the pilot to ensure they are in compliance with their country rules regarding charts in the aircraft.
If charts are not used on the MFD, the message (see photo) and the Charts tab can easily be removed by an Avionics Shop. Please have your Avionics shop contact Avidyne for support in removing this 'Update Required' message.
