Garmin 2689 LMT Time Off by 1 hour

Technically you are in EDT since we are in Daylight savings time right now. Double check your time settings that you have Auto or Automatic selected for Daylight Savings time.

When you say "It's 4:15pm EST," can I assume you meant to write 4:15pm EDT? ...or do you really want it to be Standard Time during Daylight Saving?

When you say you have the recent Time Zone map update, how recent was it? There was a recent glitch updating from version 15.00 to 16, and depending on when you updated, you'd now have 16.00, 16.01 (really 15 renamed), and now 16.02. The easiest fix is to have Garmin Express or WebUpdater check to see if there's a time zone map waiting to be installed. 16.02 is the newest although 15.00 should still give you the same hopefully correct time.

Hopefully your discussion with Garmin had them at least have you check your nuvi settings: Tap Settings/Units&Time/CurrentTime, then confirm that the clock page has the Automatic box checked and that the time on the Time Page is correct. You may need to tap the up or down arrows to see the Units&Time Setting selection. See owners manual, pp 2 and 16, especially if my "taps" are not correct to reach the time settings on your model:

http://static.garmincdn.com/pumac/nuvi_25x9_26x9_OM_EN.pdf

If for some reason you don't want the time settings to be automatic, have you manually set the clock to the correct time? I don't know why you'd want to do this when automatic is best.

Two last thoughts:

1) Have you got a good satellite fix (on the main menu, how many green bars show for the satellites) and let it stay on for about 15 minutes to fully set the GPS almanac for satellite positions, time of day, location, etc? This is especially important with a brand new device, one that's moved several hundred miles powered down, then started up again or one that hasn't been turned on with a good signal since Daylight Saving started. This is really a stretch, but maybe you need to drive a mile or so to have the new nuvi fully accept your location, settings, etc. Can we assume that your current location on the nuvi's map is spot on right now?

2) Last case scenario: you do have a really new nuvi model and as you stated, the time zone map was just updated. I suppose it's possible that there is some as-yet unreported bug resulting in a one hour error. That's probably as odd as your being in Chicago right now while thinking you're still in Connecticut.

Stick around here at The Factory. We've seen many cases where folks here can outperform Garmin Customer Service in both correctness and speed of results. Then again, there are cases where calling Customer Support is the best way to go.

Please let us know how things are progressing. Good luck and welcome again to the site.

You say that the time's been off since the last map update. Can we conclude that you updated the map a few weeks ago which was before Daylight Saving started...and that the time was always correct with the earlier map? The easiest cause that could explain these findings is that the map or other update oddly resulted in unchecking the "Automatic" time setting, meaning that your GPS has ignored updating the time of day clock and still thinks it's in winter Standard Time plus or minus a minute or so of drift. I know that on rare occasions a map or other update will oddly change the desired navigation voice to a different one, and an unchecking of the Automatic button would be a similar issue. It could also be that the Automatic was never checked, and you first noticed the time error right after Daylight Saving started. Do you have access to a clock with really accurate time? It'd be interesting to see if your nuvi is exactly one hour off or if it could be 55-65 minutes off meaning that the nuvi clock isn't reporting GPS satellite time. Here's one way to get correct time if you don't have access to a radio-controlled "atomic" clock:

http://time.is/

If your nuvi is exactly one hour off, I'm suspecting a Daylight Saving issue; if almost one hour off, then I suspect your nuvi isn't (and recently hasn't) been updating its time with the satellites because the Automatic box has been unchecked for a while.

PS: To me, Garmin's suggestion to do a Backup/Restore and a map reinstallation is not what I'd suggest as a likely fix unless there are other issues implying a corrupt map...and if the suggested Backup/Restore was what Garmin Express does as a "backup," I'd really be surprised to see that being the issue.

The only settings I have are automatic or manual.

AFAIK if you have the Nuvi set to Automatic and have a good satellite lock so that you can input a destination and the Nuvi calculates a route, then the time should be automatically set to the time in your current location.

If you have automatic set but don't have a good satellite lock then it is possible that your time reading could be out. I believe it's the satellite lock that insures the correct time is displayed.

Once the correct time is displayed, and you remain in the same time zone, the Nuvi should display the correct time whether you have a sat. lock or not. If you move to a different time zone the Nuvi will automatically correct the time if you have a sat. lock or when you first obtain a lock in the new zone.

In addition to the advice given by t923347 and others, make sure you have a valid Time Zone map file gmaptz.img. Garmin recently had an update that installed a corrupt time zone file, but that has been corrected with another update. So make sure you have installed all the recent updates for your device.

In re:

1) Yes, I believe the map was installed prior to DST

2) My GPS is/was in automatic. In order to properly get it to the right time, I have to manually set it 1 hour ahead.

3) The GPS clock is EXACTLY one hour off, minutes are perfect.

I tried doing a search for that file, but it doesn't find any such name. On 5/23 I did install another timezone update, but no such filename you are referring to can be found. Do you know the path?

In order to view some protected files on some Garmin units such as mapping image files, show hidden files and folders will need to be enabled. See http://www.poi-factory.com/node/39185 for instructions. Be careful in this area.Suggest you make a backup of your GPS first.

File still not found
Hidden is enabled.
------
I haven't left my timezone, and only to FL - but it was doing this before I left CT

Run Web updater http://www8.garmin.com/support/collection.jsp?product=999-99... .Make sure to go to 2nd page for additional updates and look for the time zone update.

I found the hidden folder - you have to go into developer mode on the GPS - to enable Mass Storage only.

1.Bring up the volume screen on the GPS.
2.On the upper right hand corner.Press your finger on screen and hold for appx 10 seconds.
3.Shortly you will see the developers screen.
4.Find MTP Settings and touch it.
5.It will show 3 selections. MTP Auto Detect,Mass Storage and Mass Storage Single Session.
6.Touch Mass Storage as your selection.
7.Now select save and you are good to go.

I followed the steps to a T from here https://forums.garmin.com/showthread.php?258359-There-was-a-... minus the Basecamp as I don't know how to use it, and 2) I think it's more for watches... and it's STILL an hour behind!
I'm about ready to throw this thing in the garbage!!!!!!!!!!

Mass storage can also be found at http://www.poi-factory.com/node/41416 . You need to run WebUpdater.

Already done that, the problem is V15 doesn't have this "bug" I tried downloading and installing and removing V16 as the link/instructions stated, but it's like it's "STUCK" and won't go to the correct time (stays 1 hour behind) exactly.

Don't follow that procedure. Garmin has fixed the TZ problem with the latest release. Just update the TZ map using Express or Web Updater and you'll be fine.

Once you run WebUpdater the old file will be replaced with the latest update that works. I installed it on my unit and all is well.

Well.... I did EXACTLY what you said and it's still an hour off. My car linked to Sirius Satellite is 644pm (ET) and the GPS says 544pm (ET) and in night mode already

Manually set the correct time per https://goo.gl/8lyvJG .Once set reboot unit then put the check mark back in automatic time setting.Make sure to get good satellite lock . See also https://goo.gl/Dn9QyD

just in case any readers are wondering how Charlie is getting these goo.gl links, just type goo.gl into your browser to find out.

Now I'm really confused. Your saying that the Nuvi is an hour behind the radio's time setting (5pm compared to 6pm) and yet the Nuvi is also in night mode? Not sure how that could be as the sun would more likely be up at 5:44pm than it would at 6:44pm and this time of your it would be up at either time so the Nuvi shouldn't be in night mode for either time.

Is the Nuvi always in night mode? What is the setting under Settings - Display - Color Mode? It should be set to Auto to enable the Nuvi to switch between night and day modes based on the local time.

Done..... no change
Had 11/10 feet accuracy on satellites

Done..... no change
Had 11/10 feet accuracy on satellites

Tell me about it!
I'm just as confused if not more. This is my first problem with Garmin, I always had Tom Tom's and nothing but issues. Last 1 one was a Garmin - never a problem, gave to a friend and now I regret it

RE: Color, if in auto, on the way to work in the morning (8AM - ET) it's in night mode, evening on way home (5PM - ET) it's on day mode for part of the 40 min ride home, then goes into night.

This is REALLY getting aggravating!!!!!!!!!

Just what locale do you have set?

What do you mean? When I go to where-to it shows my location in whatever city I'm in, when there - in CT

When you first initialized the unit (and after a factory reset) you are to pick a country where the unit will be operated. Most pick the US but some choose other locales because of options or color schemes which may not be available for the US. It has nothing to do with the unit showing your location, it's about the "rules" the unit is following when showing your location.

I chose the US

Is there a way to 100% reset the unit (I have a backup) and start all over again? Maybe there's a corrupted file?

See https://support.garmin.com/support/searchSupport/case.faces?...

Oh I've done it that way before, I thought there was a way to COMPLETELY wipe it out. Because this method, clears settings, etc - but my saved places and everything remain.

Another thing I've noticed when I've reset it - until the satellites lock in, if I hit where to - it says Chicago IL, then will change over to CT. I just did it again, and it did the ^ and in addition the time went from 8:15pm to 9:15pm (it's 10:15pm ET) now here.

I can understand your frustration. Although it isn't the end of the world, it would bug me as well until I found a solution.

Although I can't get my head around the "night mode" thing, lets tackle one thing at a time. The way your device is now it appears to be displaying the correct time for the Central Time Zone while you are actually in the Eastern Time Zone. I have a couple of ideas about why this is happening but I need to know what happens to the time if the Nuvi actually things it's in the Central Time Zone.

To accomplish this please do the following:

From the Main Menu screen - tap Settings
From the Settings screen - tap Navigation
From the Navigation screen - Tap the Down Arrow and then tap the box to the right of GPS Simulator to put a check mark there and click OK to the warning that will appear.

This will put the Nuvi in Simulation Mode so the Satellite lock will be turned off for now.

Now go back to the Main Menu screen and do the following:

Tap - Where To and in the Search Box at the top of the screen type Kansas City and tap Kansas City, MO from the list that will appear

A row should appear under the Kansas City, MO entry with an i in a circle in the middle of that line. Tap the i

On the Map screen that will appear for Kansas City, MO, tap Set Location, insure the Route Info field reads "GPS is OFF" and return to main menu screen.

The Nuvi now things it is in the Central Time Zone and specifically in Kansas City, MO. What I'd like to know is what does the time read on the main menu screen. Is that time still one hour different than the time it is in CT or is it now 2 hours different?

Once you have the answer to that you can reboot the Nuvi and it will turn the satellites back on and you'll be back to normal. Has this affected the time shown on the main screen at all? Probably not, but just checking, the more important thing is what happened to the clock when the GPS thought it was in Kansas City.

I know, it's probably something so simple though, and it's annoying. I appreciate your time/help though.

OK -- did it.
Time read/reads 8:37pm (2 hours different) than CT. It's 10:37pm here now.

Rebooted, when back to 1 hour different (behind) CT at 9:41pm rather than 10:41pm

A master reset will delete favorites. It puts unit back to factory settings.After doing the master reset.You should then run WebUpdater to get all the updates back plus downloading the time zone file on 2nd page for additional updates.

So it was out by 1 hour orginally and moving to the next time zone would have put it out by another hour. That's a total of 2 hours where if the device was working properly it should only have been out one hour (the difference between EST and CDT). That says to me that the Time Zone map would seem to be working properly (the time changed by the one hour it should have moving from EDT to CDT) and that the hour time difference issue stays the same crossing time zones (your now out 2 hours when it should only be one).

I really think this problem maybe something we can't find a solution for as it's an issue with this specific unit. So far I see at least 3 things that don't seem to be working properly with your GPS:

- the time displayed is always out by 1 hour
- night mode appears to come on at incorrect times
- if you've done a hard reset and don't have a .gpx file on the device that we don't know about you should have lost your Saved Places and that didn't happen.

It may well be time to contact Garmin Support (phone call only to 800-800-1020 - DON"T SEND AN E-Mail) as they can run diagnostics, replace your unit, etc. instead of you spending your time attempting to fix something that can't be fixed.

I agree with Rick (t923347). *CALL* Garmin and be sure to be by a PC that's connected to the internet so they can (if needed) connect to your nuvi through your PC see if something can be done remotely to correct the issue. Using email is not recommended in these types of issues as the exchange back and forth can be drawn out and Garmin will tell you to do many things you've likely already done.

Going back and forth with Garmin (through email) and here as well will do nothing if the issue is hardware related...it will just take so much longer. Call Garmin and sort the issue that way.

I looked back through the thread and still do not see that the time zone map file gmaptz.img has been located.

@ppal1981, have you located that file? You can do a Windows Explorer search for "gmaptz.img" (without the quotes)

?? what happens if there is no time zone map on the device, I wonder ??

I am also wondering why the Master Reset (see How Do I Perform A Master Reset On My Dezl/Edge/Live/Nuvi/Quest/StreetPilot/Zumo ) did not clear Saved Places like it is supposed to (unless there is a .gpx file other than current.gpx on the device).

@ppal1981, you should do a Windows Explorer "search" for ".gpx" (without the quotes) and delete any found (after having save whatever is found to somewhere on your computer)

I think I remember back when my 350 and possibly my 760 didn't have a time zone map and all that happened was that I turned on the device and it would set the local time. As I drove across time zones the time displayed on the device never changed but kept the orginal time zone time correctly. In any event the Nuvi didn't need a time zone map to correctly set the local time which is the problem here. Since it's changing the time as you cross time zines I don't think the gmaptz file is missing.

Thinking back to my first unit, a Nuvi 200 (not the 200w) it also required you to change the time zone manually. We drove across the country with it back in 2008 and I finally gave up playing with the settings and just reset it to my home TZ and did the conversions to local time as shown on the cell. The whole issue with it being off is probably the TZ map.

I just tested my nuvi 755T and my 3597LMTHD to see how they would react to a missing time zone map (I renamed the file to disable it). In both cases, when the time zone map was missing, the "automatic" setting for current time was disabled (completely missing on the 755T and greyed out on the 3597LMTHD). You could manually set the current time, but you could not set it to Automatic.

On the 755T, when I reenabled the time zone map, and put a check in the Automatic setting, I could no longer change the current time (the time adjust buttons are greyed out). On the 3597, when I reenabled the gmaptz.img file, I could check the Automatic setting and it would adjust to the correct time. If I try to change the current time to something else, it will remove the check mark from Automatic.

So my conclusion is that if you are allowed to select the Automatic setting for time, you have a valid time zone file. I have no way to know if the 2689 works the same way, but it probably does.

Edit: additional information ... I also have a nuvi 855 which does not use a time zone map. In its time settings, you have to select the time zone. Without a time zone map, I don't think nuvis of this generation have any way to know your "local time" based on your location. It gets this only from the time zone setting in the Settings menu.

Edit 2: still more information ... On my 755 and 3597, when the time zone map is disabled, I can find no way to manually specify the time zone you are in. You can change the current time (hour and minutes), but not specify a time zone. My guess is that it defaults to Central time (Olathe, KS) which would explain ppal1981's problem (if his time zone map is missing), but I can't prove it because my location is really in the Olathe time zone.

Could you explain how it could be the time zone map? You turn on the Nuvi and the time is out by an hour and it remains out my an hour as you move into a new time zone. The time changes by an hour when your in the new time zone but still remains out by an hour just like it did from the originating point. Unless I'm missing something, the time zone map appears to be working properly (the time changes when you cross into a new time zone). It's the Nuvi setting of the originating time that is bad.

Currently we are in DST in the US and Canada but the unit doesn't necessarily know the time of year so it adjusts its clock from UMT to the unadjusted TZ. The OP stated when he simulated he went to the Central TZ, the display was off by 2 hours. That mimics the issue I had with my original 200 which also didn't have a TZ map.

I believe the OP should delete all instances of GMAPTZ that may be on the unit and re-download the current version using web updater.It's possible he has more than one TZ file and has been playing with the wrong one.

I agree with Box Car's approach. If the problem remains after replacing the time zone map with the current known good version (16.02), we will know for sure that it is a different problem.

I also agree with the earlier advice given to CALL Garmin support and let them identify and hopefully solve the problem.

Not sure this proves anything or not but I'm in the Pacific Daylight Time Zone and when I disable the Time Zone map the time on my 3597 remains the same as it was before the disable (PDT). When I manually change the time to another time zone it stays at that time until I enable the time zone map at which time the Nuvi switches back to the PDT.

So much for my "theory"

Well I appreciate everyone's help but went to Best Buy and exchanged it under geek squad warranty which ended up falling under the Mfg. Warranty since it was <6 months old. So far so good. It needs updates but now I'm afraid to do them :/

Any suggestions before I do?

Switch it out of MTP and do a FULL backup

How do I do that? Can you advise steps please?

It's in the tutorial here:
http://www.poi-factory.com/node/30394

I'm glad all worked out with a replacement.

Can we conclude that it was a hardware or very odd software issue unique to the 1st nuvi?

I think it was a software issue.
Thanks everyone for the help/advice.
