GPS Week Rollover April 2019 - May affect older (pre-2010) GPS devices

I love when they say lifetime support and maps while in the small print tell you that the lifetime is the average lifetime of the device. That really means they are going to cut you loose in 5-8 years.

'Lifetime is when we say it is'.
 
Pulled out my GPSmap76 today and fired it up, it acquired and displays the correct date/time, does that mean it made it through the week count rollover successfully?? I can't update the firmware because the cable I have to connect it to a computer is so old none of my computers have that interface.
 
I'm pretty sure that if the correct date (especially the year) and time are displayed, that means your antique still works.

Best to not even attempt to change the firmware - few, if any computers that originally shipped with Windows 10 support Serial to USB adapters due to hardware (not software or driver) issues. To be assured of success, you would need to have an old computer that originally shipped with an early version of Windows 7, still running Windows 7, as well as a Serial to USB adapter.

I got a notice from TomTom, today is the day for my unit (630), however it's not happy to connect with my computer..... I'll see if I can resolve it when I get home next week.

That begs the question: How will you get home without it? :p

Next Saturday morning I point the car east and close my eyes until Monday afternoon and I will be home. I'm actually using the Chinavasion unit and the TomTom is the back-up..... haha ;)
 
Garmin says the units will still be accurate but time stamps on log files will be off. Did not see in this post any mention of specific models affected.
My Zumo 450 from 2009 (which I've always kept updated) shows the correct time. Will have to connect it and check the date on the log files tomorrow.

I guess we need to lay in a stock of dehydrated food and water.
 
I feel comforted when Garmin says

" However, the positioning accuracy will not be affected. The device will continue to deliver the same positioning performance as before the rollover."
 
Wonder how my ol' Garmin Quest-I (build 2003~2004) will behaive...
Have 3 of those unkillable, slim devices and refuse to opt on new ones (huge flat-screens are for living rooms, not the motorcycle dash... :rolleyes:)
 
Yep you'll still know where you are and how to get somewhere else (well at least as well as you did before). Time related functions will be off too. I wonder if this applies to 'universal' (not UTC/GMT/ZULU) time or 'relative' time.

That is - an affected device may not know if it's 1700 or 0040 but will it still correctly display (if it does at all) your ETA? That's really the only time function of a GPS that I have ever used.

I do have one old nüvi somewhere that's probably affected, but my other devices with GPS are fairly new so no worries.

The biggest example I've seen (here not IRL) are the 5" Chinavasion displays. Other than car displays is there something bigger for mobile satnavs?

Well, I've observed a car driver with an iPad slapped on his dash...

As long as it doesn't get in the way of the driver's operation bigger could be better assuming in the context of this thread that it's being used as a satnav and not for playing Candy Crush or making blog entries.
