My 276c is not updating the date...

My trusty, but now 14year old, 276c is not updating the date anymore.
Time, spot on, date varies between 1 Jan.
'00, 20 Aug. '00 and 8 Oct. '00

Where is the date received from?
When syncing with your laptop or from the satellite?

This unit was switched off more than a year before a week ago.

Ignore the image "no signal" , I took the picture after I parked in the garage. Before that the unit was switch on and receiving unobstructed for more than two hours, with an external antenna.

It has an internal battery which needs replacing. My 296 does the same.
If you switch it off (after having received a signal) and on again it will show the correct date etc but not store it for long.

I have always entered the date time manually on the unit, especially after the battery failed.
If I remember correctly, there is a small rechargeable battery on the circuit board somewhere.
There is a you tube video on how to replace it.
I found out the hard way to switch the unit on and recharge the battery, even from the mains at least once a month.
I had a new battery pack made up by someone in George, (have to try and find the details if you need it.)
They also had to replace some electronic component that failed and prevented the battery from recharging.

Thank you for all the feedback.

Good to hear that others have a solution for you. When I first read this, I thought you were a victim of the old 10 bit GPS string. We have a GPS at work that thinks its the year 2000 (ironically when we noticed this it read "April 1st"), due to this issue. New GPSs have a 13 bit string, which will only rollover every ~8,000 weeks.
