My Garmin ETrex thinks it is July 1999

Hello,

I have a Garmin ETrex GPS (there are no numbers after the model, it is just called ETrex).

It has been working fine but now seems to have decided to go back 20+ years and decide that the date is now 7th July 1999. This also means the sunrise/sunset times it displays are all wrong. (It's showing sunset as being about 4 hours later than it actually is, for example).

I cannot find a way to reset the time and date. When I first switch it on they now show as "------" but once it connects to the satellites, it changes to show a time that is 1 hour ahead and a date in July 1999 (it increments the day each day).

Does anyone know how I can get it working properly again?

    If you have one of the original ETrex's and you have what ever Garmin's last offering for firmware installed on it, then there might be nothing you can do about it. You might try to double check what firmware/software is installed on it and what Garmin shows as the last firmware/software update available.

    My circa 2005 gpsmap 76CSx still shows correct date. I'd never expect these devices to work correctly forever. All my GPS's that are no longer getting updated by Garmin are either just spares just in case the current models I have quit while I out where I can't get a replacement. Or they are for completely recreational use such as my Garmin Edge 500 for cycling.

    That update did the trick for me. It's working again now and in the present time and date!

    However the link posted above will tell you to install "Garmin Express" to install the update it. It doesn't work (or at least, it didn't for me). It would not recognise my GPS.

    However I found another link : https://support.garmin.com/en-GB/?productID=8705&tab=software

    Get the WebUpdater tool. This was able to recognise my GPS and updated it to the 3.60 firmware for me. This has corrected the problem. Thanks for your help!
