GPSMAP 58x Time and Date are Incorrect

We have identified and corrected an issue with this product that causes the date and/or time to be wrong after the GPS Rollover on April 6th, 2019. However, all functions not dependent on date and/or time will continue to work normally. To resolve this, a software update is required.

What happens if I don't update the software?

• 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

How do I update the software?
