Check your GPS, particularly if it is an older one. It might not work:

Y2K for GPS.

It'll be interesting to see who made GPSs so cheaply, and when, that they didn't expect them to last as long as May, 2019.

They will work just fine, only the ability to get UTC time is possibly impacted.

After reading the document a few times it does sound like the GPS time is used for navigation and only converted to UTC time to display that for the user.  It also sounds like the UTC time conversion is the only thing impacted, so yes navigation should still work.  At least that was my read.  My understanding of the technology is limited though, so I could be reading this wrong.

Exactly right. A bunch of us with old Garmins sold with software and technical support as BMW motorcycle NAV Vs had a temporary reversion to year -00 until the most recent firmware upgrade.
