Hello dear Kenwood-Garmin community.

I have a DNX9260BT, which started to behave strangely recently: It stopped getting automatically the correct date (and thus also time) via GPS. For example Instead of 7th Aug 2020 the date is 22nd Dec 2000. UTC time is correct, but since the date is wrong, the DST offset does not get applied and time is off by one hour. Most annoyingly though, is that day and night mode of the display does not switch correctly, due to the wrong date.

Has anyone else already seen this behavoiur? Any clues or hints on what to try, how to troubleshoot this issue?

Thanks for your replies, your help will be very much appreciated!
