Guest cleenjeep Posted June 12, 2001 Share Posted June 12, 2001 is wrong. It shows it is 3:57 when it is clearly noon. I dont understand where to change that. It wont let me select the time on the setup page. I know this isnt a crucial point on my GPS, but it is annoying. Can someone tell me how to change this?

Guest martinp13 Posted June 12, 2001 Share Posted June 12, 2001 I believe the time comes down from Up Above. No, not God, silly... the GPS satellites. ------------------ > Martin Magellan 330 (gonna load WAAS update soon!) Don't have time to program and record your shows while geocaching? Get a TiVo !

Guest leaper64 Posted June 12, 2001 Share Posted June 12, 2001 cleenjeep, i'm going from memory here but i think you need to adjust your time offset. you should find it on your setup menu. for your area, offset should be 6 (i think). Quote Link to comment
Guest mazda626 Posted June 12, 2001 Share Posted June 12, 2001 Look for "Offset" under "System" in the "Setup Menu". The offset is -06:00 hours for Mountain Daylight time. Quote Link to comment
Guest cleenjeep Posted June 12, 2001 Share Posted June 12, 2001 Yup, thats what that offset was for.. I had to offset to -4 thanks! Michael ------------------ Webmaster and List Admin for Southern Michigan Rockcrawlers Personal Site is Cleenjeep's Site Quote Link to comment
+Psyop Posted April 12, 2005 Share Posted April 12, 2005 My problem is that the date on the system setup screen is 31 July 86. Which is just a bit off of the actual date of 10 April 05. Is there any way to get the date a little less than nine years out?? This has been bugging me for more than a little while now. Quote Link to comment
+PDOP's Posted April 12, 2005 Share Posted April 12, 2005 The instruction below are from a Yahoo group. It can't hurt to try them I received the following advice from Garmin UK by phone earlier today - ANDIT WORKED!! I have not found this published elsewhere so it seems worth circulating for others who get problems with their GPS 12 showing the wrong date - you may recall ours showed the date to be 2048 weeks ahead - June 2044. Inevitably it is your risk if you try this!! 1 Switch off 2 Press MARK and power on together. 3 When it says "do you wish to delete data" it should default to YES. 4 Switch it to NO, 5 then switch it back to YES, 6 then switch it back to NO, 7 then switch it back to YES 8 finally press ENTER The device then does a very slow recovery as it acquires data from the satellites and may even show incorrect dates until fully recovered but at the end 10 -15 minutes all is/was well! All the best, sorry if it seems messy,. It's not April 1st and it worked !! Quote Link to comment

+Sputnik 57 Posted April 12, 2005 Share Posted April 12, 2005 Who are all these "unregistered" dudes @ top of the thread? Check the date on those posts. Psyop obviosly knows how to use the "search" feature and looked for past threads. He happened to dig one up that was nearly 4 years old. The forum software has changed since then. Kudos to Psyop for searching for an answer first, and to PDOP's for coming up with a possible solution (however improbably it seems). Quote Link to comment
+Greymane Posted April 12, 2005 Share Posted April 12, 2005 This is a common problem among SiRF chips (and some other units). It comes from a garbled data input from the satellites. Usually caused by a poor signal while generating the almanac. The date error will always be 1024 weeks off (or a multiple of this). With the SiRF chips in the NAVMAN and MIO Pocket PC units, you need to get a reset utility that will reset the GPS to factory settings and then reacquire the almanac data. Quote Link to comment
+habot Posted April 12, 2005 Share Posted April 12, 2005 GPSEow.exe can maybe help you to restore your GPS information. Quote Link to comment

reidster Posted April 18, 2005 Share Posted April 18, 2005 The date error will always be 1024 weeks off (or a multiple of this).I know this may be a little OT, but seeing the 1K week error reminded me about GPS timing. Here is an FYI article about this and the cursed 1K roll-over problem...Earth Observation Magazine, What is the GPS Week Rollover? Quote Link to comment
