GPS Week Roll Over Issue (affecting SatNav ETA / GPS signal)

Hi guys, after reading many of us having trouble with SatNav ETA and a GPS signal lost, here what seems to be the root cause:

https://www.us-cert.gov/sites/default/file...S_2019.pdf

From what happened at forum members, only the people have had the battery replaced are suffering these issues due to navigation sys reset during battery disconnection.

It result in a missing syncro between the GPS signal time and the firmware counter inside the navigation system.

Now the question is: anybody have an idea about the possibility of update the firmware of the SatNav system?

Cheers

Assuming it doesn't have the same problem


Although it's not compatible with your GVIF
