My F900 seems to think that Oregon is in a different time zone from Washington. It will jump ahead 1 hour when I am driving across the Astoria Bridge, heading to Astoria, Oregon. Then, on my way back home (Washington) it will go back 1 hour.
Any thoughts as to why this is happening?
Thanks all.
Have you tried adjusting your Flux Capacitor? Time travel can be dangerous. 
ha! i guess i better. 
anyone else have any thoughts on this?
I think under nav settings there are time update options with DST on/off?
But, yeah it doesn't make sense for the time to change though since you're entering the same time zone.
Yeah, I live in Portland, OR and when I let the GPS set the clock it sets it 1 hour ahead. Taking it back to self-set on the time zone and choosing PDT puts it back to the right time. No idea why, maybe it thinks I'm in AZ where they don't do DST. 
EDIT: Turns out the GPS is placing me in Mountain Standard Time (Boise is auto selected!). The GPS/Time menu indicates I've got excellent signal to multiple satellites, so WTF? I'll have to check my Garmin later to see which time zone that one's detecting...
Thanks for the replies - I'll look around in the settings to see if I find anything weird...
Google search produced this little gem (http://www.navngo.com/pages/global/eng/ ... upport_faq):
Time-Zone Error in Nav N Go iGO 8We inform you that, in the R1 versions of Nav N Go iGO 8, the Windows time zone may be incorrectly set depending on the GPS position (for instance, Minsk is selected for Hungary). The correction is already released in R1 patch (see above).
The update now can be downloaded free of charge with the use of the Content Manager.
Also, a workaround is available on your device by editing: /Program Files/iGO8/sys.txt and adding the following lines:
[timezone]
sync_os_timezone=0
reset_os_timezone=0
Attention: The modifications will only be activated when Nav N Go iGO 8 is restarted.
The latest Nav N Go iGO 8 R1 patch (see above) provides a fix for this error.
So hopefully the next vaporware update from Pioneer will patch iGo 8 to fix it. Nav N Go didn't have a patch file posted for Pioneer anywhere I could see, it required the device be able to connect to your PC via USB...
NavNGo themselves only provide patches for standalone PDA versions of the product (and their own branded Limuzin PNA). Versions integrated into branded devices (i.e. old Mios, IPAQ 31x, Pioneer etc.) need to be updated by the manufacturer because they are custom builds...
Just a note to document that the 2.0 update did NOT fix the known iGo timezone bug, at least not for my unit (F90BT in Portland, Oregon, NOT Boise, Idaho like it still claims).
So we probably need the latest version of iGo to fix this issue.
Hopefully Pioneer will address it with an update. For now, I just turned off the auto clock setting.
The F series is definitely a work in progress. Maybe someday it will work flawlessly... but that's a definite 'maybe'.
