I noticed that my BMW GSA instrument panel date was off but the time was still correct. I reset the date in set up and after restarting the bike it would reset to the March 24 2000 date. I eventually realized the GPS Nav V was the problem. Contacted Garmin and this is what they have to say. Just a heads up if others are experiencing the same problem.



Feedback from Garmin

Thank you for contacting Product Support.

We’ve identified an issue with this product that causes the date and/or time to be wrong after the GPS Rollover on November 3rd, 2019. However, all functions not dependent on date and/or time will continue to work normally.

For the BMW Motorrad NAV IV - update the device software by following the steps in Updating Automotive Maps and Software with Garmin Express to correct the issue.

For the BMW Motorrad NAV V - We are currently working on a software update that will address this issue.

What does that mean for my Garmin?

The date and/or time determined by the GPS will be wrong
Position, velocity, navigation, and all other functionality not dependent on date and/or time will continue to work normally

What is GPS Week Rollover?

The GPS satellite system communicates the date via a week number that is limited to 1024 weeks (about 20 years). On November 3rd, 2019 the week numbers broadcast by the satellites will “rollover” to zero. If GPS receivers don’t account for this rollover in their software, it will calculate the wrong date and/or time.
