The GPS Week Number Roll-over (WNRO) on 6 April 2019 may have an impact on GPS performance. If you frequently update your device there’s no need to worry!
Current navigation devices (Nav4) are not affected.
Sports and Action devices are not affected.
Some older navigation devices (Nav3 = using to MyDrive Connect and Nav2 = using HOME) may be affected.
Hi, as most I have received an email advising of the above and updated my built in device today following the instructions. It is now back in the car and I noticed it had replaced my car symbol with a solid arrow. I change preferences back to car symbol again, it tells me it has changed but the solid arrow is still there. Is there any additional update that maybe causing this issue or is it a bug in the update? Would like to know if anyone else has had this?

Is there a list of devices which cannot be updated? I tried the serial number of an ONE XL which I have lying around and it said it cannot be updated. Apart from entering the serial numbers for every device, can you confirm by model which wont be updatable??

Hi, I have an older type GO720. When I try to update the new software for the GPS week it requests that I transfer existing software from my device to my PC as there is insufficient data space available on my GO720 to install the update. To do this I would have to remove everything (map and voices etc) to accommodate the new software update?

It's automatically selected for you. I'd suggest you uncheck the other choices till the application is the only one selected to download and install.
Then do the others.

Is TT really sure some of our devices WILL be affected or is it just a precautionary announcement/scare story/rush out of modified applications/navcores?
Apparently the end of the epoch Week Number Rollover is exactly what it says ... it is a WEEK NUMBER rollover ... so the only devices that are affected are those that use/calculate "weeks" and utilise the "week number" index !!
As most SatNavs don't even use date/day information but simply use "time" then they will NOT be affected !!
At the bottom it very clearly states:-
"This situation won’t affect a receiver’s ability to navigate and/or calculate precise time, but it has the potential to create week, month and year timestamps that are wildly wrong. Applications which rely on GPS data at that level may be seriously affected"
