GPS Rollover week 6th April

#21
Interesting! Garmin say that GPS positioning accuracy won't be affected, so navigation itself will still be as before the rollover :unsure:

Tom tom do claim that without an update the satnav will not work at all.

There are three issues that 'might' happen

Without updating, these devices may experience some of the following issues:
Tomtom said:
  1. No time
  2. Frequent loss of GPS fix
  3. No GPS fix at all - navigation impossible
Maggy has a tomtom one xxl which will have the following issue

Your satnav’s status

After 6 April 2019, your satnav will continue to navigate, but it will not show the correct time and the estimated time of arrival.

I have a few which will not be affected but my old go730 when I checked it says

After 6 April 2019, your satnav will not be able to navigate. Fortunately, this is easily fixed with an update we have ready for you below.
If you put your serial number in here it will tell you how yours will be affected

Confusing eh? I guess we just have to follow the advice of the brand we've got... which in Garmin's case is just that most devices won't have a problem. Yes, it's important to update, which I do, about once a month usually.

I do have a seriously ancient TomTom One from 2005 stuck in a cupboard somewhere, which I have no doubt won't work any more! :LOL:

This thread reads like a April 1 st wind up surely they'd have known this was to happen before now and corrected it in past updates

Yes they've known since 21st August 1999, when the first rollover was triggered... but this one will still happen because the system software allows for just 1024 weeks to be counted off. It won't cause any major dramas I doubt, other than for really old devices, because all they have to do is reset the programming with the right date and time for the beginning of the next 1024 weeks.

I know the news about this is more visible now but I remember reading about it a few months ago. I've just never been sure - still not really - if it will make any difference to update before 6th April or not. I have updated three months in a row since I read about the issue but there's no way to tell if that's fixed something that's not supposed to happen for another few weeks, if you see what I mean! I get the impression from reading about it that the 1024 week programming is also part of the satellites that GPS uses. Hmmm, I wonder if someone's going to fly up there with the fix on a memory stick :unsure:;)

I updated my garmin this afternoon, and also my old tomtom which we use in the States. I’ll have to wait until October to see if it works.

In order to be sure that my unit would continue to work OK after the week number rollover (when I will be in Europe), I submitted a support request, detailing my unit model and serial number. Garmin Europe responded with a link to their web page with generic information (as referenced above and from which I had quoted in my query) - not exactly helpful!
A telephone conversation with them has elicited the information that units affected by the week number rollover are the Dashcam 20 and Dashcam 30, so hopefully all navigation devices will be OK.

I've just checked our Tom Tom via the link and we will have no issues (y) but if we don't arrive at Whitwell & Reepham........they lied :(

Fit an android unit and download Sygic offline maps then no issues at all :) Wonder how many fixed vehicle GPS systems will deal with it. My car one is Navteq/HERE system and apparently will have no effect.
