Daylight Savings Time

Check http://www.garmin.com/support/blosp.jsp or use the Web Updater to see if there is new software for your unit. If there is none by this weekend, refer to your unit's instruction manual and change the DST setting manually and when updated software is released and installed, fix the setting back.

Will do.
Thanks for the information.

No announced fix for the upcoming DST change for the Nuvi 660. Is that because it doesn't need one? If it needs one, we're getting awfully close to the date when we need it with no announcement at all!

There are a lot of Products out there that will need this change and some of them cant or havent released any fixes.. We will be fixxing alot of things like older TV's and clocks.. This is like a mini Y2K issue!

I think it would update automatically with the next software update from Garmin.

But the point is that DST starts this Sunday, and some of the GPS firmware hasn't been updated to include this. But as has been posted, if you are in this situation, you can manually change it.
.

How do you manually change the time on a nuvi 660? I don't see anywhere to do that!

Nuvi and every other GPS should pick up the time from the satellite when you turn the unit on (obviously you have to be outdoors) and it should be the correct time based on the time zone you selected.

In the 350, Hit settings on the main menu, then select time, then you can hit the Daylight Saving option, and select "On" instead of "Auto" if you have that option.

The time displayed is an offset from UTC (Coordinated Universal Time; aka GMT: Greenwich mean time). The User option for the Time Zone tells the unit what offset to use for displaying the time - and the "Daylight Saving"option tweaks that offset by +1 hour when on.

Example: Central Time in the US is UTC -6 for Standard time, and UTC -5 for Daylight Saving Time.

I guess, for now, we have to change time-zone (manually) and disable the DST feature (no use anymore) such that the GPS devices can calculate the correct time base on UTC offset (until the next software update from Garmin).

My 350, with software version 4.30, does not have the menu options as I noted above...

Here's how to get to the settings as I did on my unit: Select settings on the main screen, then select "Locale", then selected the time...here's where it gets sort of weird...when you hit the "time" - you get a screen to select the format - change it to UTC, then go back to the "Locale" main screen - hit the time again, switch back to 12 hour, and when you hit OK, you can progress through additional options to set your time zone, and, select a daylight saving preference...that is where you'll have to manually turn it on until software is updated - then you can go back there and set it to "auto".

By the way - the e-mail I just received from Garmin says this is the work-around until the software is updated.

i just upgraded the software on my 2730...the update info says that it should be compatible with the DST changes...check online for all software updates.

Especially if you have updated your unit software to the last one available - go to: http://www.garmin.com/support/userManual.jsp and find your model, and get the latest manual available. Had I done that, my post previous to this one on this topic would not have been made....

I thought the time is updated automatically from the satellites you just choose the time zone.

This is correct, however, the time from the satellites is Universal Time. Your GPSr then takes that information and adjusts it based on the time zone you choose.

For example, UT 1100 would produce 6:00am in EST.

If you have DST selected, then EDT is UT -6 hours instead of -5 hours.

However, if your GPSr thinks the Daylight Saving Time starts in April instead of March 11, then the time will be off for the next three weeks.

You should be able to get around this by just temporarily changing your timezone.
.

...and fix that setting once Garmin releases corrective firmware for your unit - at least that's what they told me in the e-mail I got from Tech Support...

I contacted Garmin regarding my new 2820. There is a software patch that will be ready soon. For now, they suggest switching from "auto" to "on" until the patch is ready. I'm sure if you check with Garmin, they will be able to tell you about your specific model.

Garmin has (finally! with two days to go!) released the patch for DST for the nuvi 660! They're now at software version 3.50.

You should have a manual for the Garmin Nuvi 660 it will tell you there how to change the time if you don't have a manual or lost it you can go to www.garmin.com and download load the manual for free it is in PDF form so you should have Acrobat Reader installed on your PC to open the file

Anyone having any problems since DST went into effect? My friends Nuvi 350 wasn't tracking properly this morning. It kept getting lost and saying she was somewhere else...

Ask her to uncheck the box next to TwiLight Zone:)

(just joking)

Was she in the city? (tall buildings)
My 660 is useless in the city of Philadelphia, even with the external ant. hooked up.
It just keeps recalculating and making right turns.

But this took place before the latest update.

I used my 350 yesterday and all was well. I did make sure to go into the settings and change the DST setting from "auto" to "on".

synchronizes with GPS satelite.

Go into time on the gps and take off auto for daylight saving time and then it will pickup correct time off the satellite. It worked for me.

I did the same for my c340 and it worked.

Just went into
Configuration
Time
Daylight Saving = On

If left on "Auto" it won't display the correct time.

they have a new patch to repair this

Checked Garmin site and the only c3xx without the updated software is still the c340 (Sept 2006).

Garmin c340 software finally updated, 3/20/07 which includes the up to date daylight savings fix.

Mama, I had this note on my screen which said the 880 detected a change of time zone. It thought I was Eastern time. I told it NO, and then went to my TIME under Settings. The only options were Time Format (12, 24, UTC) and Zone. Nothing about DST or Auto or anything.

However, the time on the display top right of the screen shows the same time as my computer, which changes automatically without my intervention. So evidently I do not have to make a selection for DST with this unit. It matches its time with the spot where it finds itself. In this case, Mobile AL.
