The GPS Week Number Rollover (WNRO) occurs every 19 years, with the next roll over taking place on 6 April 2019 (today). Similar to odometers in older cars rolling over from 99,999 km to 0, the GPS WNRO is the resetting of the GPS calendar back to 0.

When the calendar resets, it can cause a miscommunication between GPS satellites and GPS receiver chips. As a result, some chips in satnavs will lose the ability to process certain functions.

What does this mean for you? It’s time to check your satnav. Depending on your device, you may need to update or upgrade.
 
Isn't very old units (10 years or more) that's liable to be affected?
 
I know nothing but I assume it should be a software update

It affected my 2 week old Garmin 770 !!
Constantly recalculating all the time.
Got home, did a factory reset and updated it using Express..
All good now

To be pedantic , it is a firmware update :-)
