GPS Week Number Rollover
 

I have a stand alone Tom Tom Satnav which I use mainly when abroad in hire cars, though more frequently these days even the most basic of hire cars has in built SatNav, and of course good old Google Maps is always available too. I have had to upgrade the firmware on the TomTom to cope with this rollover thing. Does anyone know if our very old, but reliable, RNS-D SatNav will cope with this. Did try to Google it but most of what came back was way too tech speak for a simple country boy like me. Guess I also need to know if the MMI in the RS6 will be OK too I suppose. :Confused:

TIA

ETA Simplistic Definition of what it is from TomTom..

"The GPS Week Number Rollover (WNRO) occurs every 19 years, with the next roll over taking place on 6 April 2019. Similar to odometers in older cars rolling over from 99,999 km to 0, the GPS WNRO is the resetting of the GPS calendar back to 0.
When the calendar resets, it can cause a miscommunication between GPS satellites and GPS receiver chips. As a result, some chips in satnavs will lose the ability to process certain functions. "

I wondered about this when I read about the issue.....

I guess time will tell. Not sure if the motor manufacturers will bother with such old kit ?

Or more to the point, if it breaks, I can't see them making an effort to fix it so far past manufacture ?

Theres a strong argument that of the few remaining cars (relatively) that run that old kit, even fewer of the people using them probably rely on, or care about the quite dated sat nav.

It will be interesting to see what happens....

I know what you mean about the use of the old tech, but there is something very reassuring about the old "German Dominatrix" voice that the RNS-D uses...and no other SatNav I have used has ever emulated it....:D

Interesting indeed, I still use my RNS-D so I'll wait with bated breath!
(It's 5 days before my bus pass becomes 10!)
Though given that RNS-Ds were working fine 19 years ago, as the previous rollover approached, I very much doubt anything will happen. :p

Reminds me vaguely of New Years Eve 1999 when I went to a massive party and was the only one among my friends not drinking, except a small glass of champers at midnight, as I was the Global IT Infrastructure manager for a global corporation at the time. :cool:
Though as our NZ, Aussie, Asian, Middle Eastern through to European systems had already moved to 2000 without a problem I wasn't too worried. :D

And there was me thinking that this was some sort of lottery that hadn't been won! :D

Having just read an article about it (link below), it appears that this 'rollover' event also happened in August 1999, so it's nothing new. One would assume that any issues that happened then will re-occur again. Other articles are going down the doom and gloom route, and comparing it to the Y2K hullabaloo, which, other than occupying me for six months recoding all the date fields in the systems used in the NICS, didn't amount to much.

I suspect it's a firmware issue with the specific chipset in the TomTom concerned (probably a character limitation) rather than a generic GPS issue.

I have a TomTom bought in about 2009 for a road trip to Italy - it last got used in the summer when my uncle was over from Australia. Will leave it switched off until after the 6 April and see if it picks up GPS reception still :)

I gather it will still connect and navigate OK Adrian, seems some date/time/arrival stuff could potentially be screwed, but agree it appears to be a particular issue with TomTom. Probably like Y2K it will be a non event:ROFL:
