I'm surprised that the GPS WNRO (week number roll over) has not received more publicity. The 10 bit week number count means that every 19.7 years it starts again at zero and this happens next on April 6/7 2019. This can (and will!) affect older GPS units not designed to accommodate this. Time and date information displayed could become erroneous. You can read more about it here:-

I had an email from Tom Tom regarding my old GPS to inform me that it is not compliant and they are not going to update it but will give me a 30% discount on a new one (I don't use it anymore so not a problem). My smartphone got a system update yesterday to deal with the problem even though it is only two years old.

I suspect a great many people worldwide are going to wonder what has happened to their Satnavs, smartphones etc in a day or two's time.

Interesting - I have spent lots of time earlier this week trying to get my wife's mobile phone to accept the correct date but it always comes up with an error message. It accepted 4th April 2009 but not 2019 ( it's an old and simple type - of course i mean the phone! ) so this may be the cause. I wonder if an old phone- Samsung C300 will correct itself?

But I also wonder if this could be a left over April Fools joke......

Oops, finger fumble. It might turn out to be a big bug though!

Last time we had this, a machine I used in work was declared millennium bug non compliant. So new machines were developed. And purchased at quite a few thousand apiece in time, and training supplied to use them, so processes were not disrupted

Out of curiosity I ran an old machine after the dreaded date. Worked perfectly. O the joys of capalism.

At the end of 1999 I was working abroad in a developing country. The Americans were told by their embassy to stock pile so many gallons of petrol, loads of food stuffs, etc etc. The British embassy just told us Brits to make sure we had a couple of litres of water put by in case!

The instructions for my new dashcam said that it got its time and date from the GPS satellites.

TRue, it started up with the correct time and date. However when we went over to Summer time it didn't change. I had to correct it manually.

Spot on Alan, early Tom Tom does not now auto update on the time

And this means that there is no ETA on your journey

But Tom Tom have kindly put on their site a Fix, that gives you at least an ETA based on the time you switch on

I don't suppose you could provide a link to the fix could you Denis?

Gary, it is the Tom Tom App, I used from original registration of the sat Nav on my PC

Over the years, this has updated the device with road changes etc

Thanks Denis.

I'll connect it to the PC to see what happens.
