GNS 530 reset time to the past

Hello aviators!
Garmin is installed on a ka32a11вс helicopter.
It is used as a reference system – no commands are sent to the autopilot from Garmin.
Communication only with the RMI(Bendix King) indicator and the route on the FPD / ND display.
Recently, the system began to display the message “GNS failure” – while the failure of the Garmin itself on the message page is empty.
There are also no reports of a dead battery.
I found that the time for the GPS is loaded for some reason “from the past.”
Photos date 05/02/2022, and Garmin shows 16/09/2002.
I have no idea why this is happening…

The firmware was not updated, as Garmin is installed from the factory and we use it.
Yes, and the new firmware for this device 5.40 is already installed.
We have a second helicopter and the same Garmin – everything is on it without errors and the date is not reset.
Seems to me a problem with a specific Garmin.

This looks to me like a GPS week number rollover issue. Update the firmware (or is the navigation database? I’m not sure right now) and the issue should be solved.
