If your GPS appears to malfunction

Should be interesting to see what happens with the 20 yr. old Garmin GPS that I use in my plane (I can still buy map updates for it). I suspect it will be OK, as it survived the previous rollover back in 1999. I would be surprised that any GPS manufactured in the last 20 years would be affected.

I did have a mid 90s Magellan GPS that didn't survive the first date rollover.
