GPS Week Number Rollover [WNRO] JUST Findings, Fixes, and Frustrations

No problems with my Go920 (Sirf Star) and NC 9.702. Some seconds after recognition the satellites time is correct (I use a suicide.dat, that's why my TT is allways starting with 00.00).
P.S: the file glgps isn't made for Sirf Star models. You can delete it and your Go x20/30/7000 is working nevertheless without any problems.
Replacing glgps on these devices is nonsense ...

Definitely "no". Tested on my 920 (9.702) and 730 (9.510). Both without any changes after 07.April.
Not quite true . Today i delete the file glgps and it works anyway.

@Alfred_ML

Indeed Alfred as soon as a satellite is received everything is at 00:00
This One XL of serial number starting with L1 now runs on Navcore 9.510
My other One, that little square box, from serial number starting with PB shows the same behavior, with 9.541

When I now plan a route to a place on our coast in both, the clock initially stays at 00:00 but both indicate the correct time for the duration of the ride.

If I switch both off and do a hard reset, then the route is still on and when the demo is now started on both the clock shows the correct time and also the correct duration of the ride. The route demo work also fine, without a single problem.

I had a completely different experience last Wednesday with my Rider v2 with Navore with the famous winding route option 9,500.
At home everything was still normal, clock indicated the correct time, route set for a ride to Arnhem, my motorcycle was still in the backyard when setting up, everything turned off again to take something with me.

When starting before departure it usually takes a while before there is a signal, unfortunately this time the experience was totally different, no signal. After driving around 50Km without even receiving 1 satellite, I stopped by a gas station.

The Rider v2 was reset and further on my way to Arnhem, only about 5KM before my destination was my route suddenly there, it's good that there are still signposts along and above the road, otherwise I would still be there been searching.

On the way back, also after a reset and keeping a good satellite signal with the right clock in hand, but once again on the motorcycle on the way home this time no route seen.

Arrived at home later in the evening TomTom Home started and a QuickGPSfix was offered spontaneously, after this update at least 9 satellites were received within a few minutes without any difficulty.

At the moment the situation is that I don't see any satellite on the status bar, the position and the clock are displayed correctly and the same route to the coastal city including the route demo are displayed correctly.

With magic, another old hobby from a long time ago, a single simple trick I do immediately, but performing miracles usually take much longer.
But I realy don't understand anything of this
