Re: Stus-List Older GPS units may have issue after April 6, 2019
Dennis; I’m not sure how this date reset will impact our chart plotters, but I notice all the articles seem to focus on problems with GPS in cars. And some say that there should be little or no problem with the apps on phones and tablets that rely on GPS. Thinking back to the carious GPS units I’ve had on boats dating back to the early 90s – which includes some pretty old Magellan handhelds, for example, plus the handheld backups I have on the boat right now (when I have let the batteries go completely dead by neglecting them) – they seem to have an initialization process that starts with a default position someplace in Japan or on the west coast, they acquire satellite signals, and use the time signal from the satellites to reset to the time and adjust to the current position. As I recall, that process of initialization can take up to about 15 minutes from a cold start. Maybe, if the plotter is wrong on April 7th, the thing to do is to completely power it down and reinitialize from scratch?

I would expect 1023 (10 bit counter); if 1024 – you need 11 bits (odd, very odd).

Re: Stus-List Older GPS units may have issue after April 6, 2019
Try it on April 7th, and if it doesn't work see if Garmin is offering a firmware update for it. You'd probably need a computer connection cable to put an update on it, which may cost more than the unit... This is a classic "own goal" thing, they (the system designers, not Garmin) set up the system with a small date range and created another version of the Y2K problem.
