Thread: GPS Week Number Rollover (WNRO) issue with IGO Primo under WINCE

When I set my stereo to autostart navigation an with various combinations of these settings:
[timezone]
sync_os_timezone=0
sync_time=0
use_auto=0

I actually managed to change the time on my unit. However, it is really only changed - not correct. Or, to be precise, it's correct when I start iGO and there is clock which shows correct time. When I close it, the stereo interface shows wrong time.

It seems to me that when I force the stereo UI to use the "iGO time", then it would be only about finding the correct time zone settings. However, I don't know how to configure this in the sys.txt.
There are settings in sys.txt (or actually system.ini in Primo) like "last_sync_time" and similar, where, when I put "some" time and date, it forces this to the stereo UI. This would be perfect, but I don't know how to set it to "now" - so it forces the current time and date that it gets from GPS. I hope at least someone understands this train of thoughts.

Second observation is, that I can leave the above settings in their "default" mode, so they don't force anything to the system and then the stereo on boot (with navi autostart) shows some time and date, but completely wrong - years in the future, and it also seems that the difference between now and the time/date it's different every time, at least the hours are different - for example: at 7am it sets the clock to 1:32pm and the same happens at 3pm - it sets the clock to lets say 1:22pm. So it's not only hours that are different, but minutes as well, leaving some timezone difference out of question.


My hope (aside from miraclously finding a new FW for my unit) is in the first scenario, finding some correct settings, to force the unit the current time and date. Any input on this would be very appreciated!
