I think you need to press the the hard menu button a couple of times and you will get to the time setting. Good Luck.

Tony,

If yours is like mine...just touch the screen where the clock is.
Then touch "SET"
It will change to the screen where you can set the clock.
Then touch the "NAV" button or the "AUDIO" button to exit and go back to the main screen.
Thats all there is to it.
:cool2:

Yeah...I thought so too.
Reckon thats what we get for "THINKING" :D :D

The Navigation system does use the satellite time for determining location. However, the DST setting will not change automatically. This is true of all GPS units whether or not they are in a car or separate units. The change must be done manually by turning the DST setting on or off. There are many different threads on this subject. If you wait for this to happen automatically, you will wait forever. There is no TSB, there is nothing wrong with the programming, it doesn't matter what you "assume" or "think," or how much you paid for the car. Change over from DST to no-DST or vice-versa will not happen automatically.

Ted, The Garmin units update DST automatically.

Fortunately you are wrong. I do not know for sure if all units change automatically, but Tom Tom and Garmin units do change automatically just as cell phones do. Go thru various time zones while driving and they pick up on the local time. I have them in different cars and they work fine.

Fortunantly I am right.

I have several GPS units (three to be exact), all Garmin and none of them update the DST setting automatically. Picking up local time does not mean that the DST setting is changed automatically. It is not changed automatically. That is all that I said. As far as cell phones are concerned, they get their time from the system they are on at the moment, not from satellites. There is a big difference between the way GPS units get time and the way cell phones get time. If the time from the system that a cell phone is on has been updated for the DST change, then the time shown on the phone will be correct. GPS units do not work this way.

Daylight Savings Time (DST) change and your GPS: What you need to know



It's March 11th and the new Daylight Savings Time went into effect today. Your PC and cell phone no doubt auto-updated themselves are are displaying the correct time. The situation with your GPS, however, is not so simple. Here's a breakdown of each GPS, how the new DST effects it, and what you need to do to get the correct time:

GPS STATUS
Garmin nuvi 350 Unit does not show the correct time. No update is available (yet) from Garmin. Workaround is to manually change the time via Settings -> Locale -> Clock.
Garmin nuvi 610 Correct time displayed when version 3.50 is installed (released March 5 2007)
Garmin nuvi 660 Correct time displayed when version 3.50 is installed (released March 5 2007)
Garmin nuvi 680 Unit does not show the correct time. No update is available (yet) from Garmin. Workaround is to manually change the time via Settings -> Locale -> Clock.
Garmin StreetPilot 7500 Correct time displayed when version 5.00 is installed (released March 9, 2007)
Garmin StreetPilot 2820 Correct time displayed when version 4.00 is installed (released March 9, 2007)

Garmin StreetPilot c530 Correct time displayed when version 5.30 is installed (released March 8, 2007)
Garmin StreetPilot c310 Correct time displayed when version 5.40 is installed (released March 8, 2007)
Garmin StreetPilot c320 Correct time displayed when version 5.40 is installed (released March 8, 2007)
Garmin StreetPilot c330 Correct time displayed when version 5.40 is installed (released March 8, 2007)
Garmin StreetPilot c510 Correct time displayed when version 5.30 is installed (released March 8, 2007)
Garmin StreetPilot c550 Correct time displayed when version 5.30 is installed (released March 8, 2007)
Garmin StreetPilot i2 Correct time displayed when version 3.30 is installed (released March 1, 2007)
Garmin StreetPilot i3 Correct time displayed when version 3.30 is installed (released March 1, 2007)
Garmin StreetPilot i5 Correct time displayed when version 3.30 is installed (released March 1, 2007)
Garmin GPSMAP 60Cx Correct time displayed when version 3.20 is installed (released March 5, 2007)
Garmin GPSMAP 60CSx Correct time displayed when version 3.20 is installed (released March 5, 2007)
Garmin GPSMAP 76CSx Correct time displayed when version 3.20 is installed (released March 5, 2007)
Garmin GPSMAP 76Cx Correct time displayed when version 3.20 is installed (released March 5, 2007)
Magellan CrossoverGPS Time is not displayed, so this is less of an issue. No updates are available for the CrossoverGPS
Magellan RoadMate 2000 Time is not displayed, so this is less of an issue. Still, you should upgrade to version 1.56
Magellan RoadMate 2200T Time is not displayed, so this is less of an issue. Still you should upgrade to version 1.56
Magellan RoadMate 3000T You should update to version 3.11
Magellan RoadMate 6000T You should update to version 1.22
TomTom GO 910 Update available via TomTom's HOME application
TomTom ONE Unit does not show the correct time. No update is available from TomTom. Workaround is to manually set the clock.

The bottom line on GPS/DST is that the raw satellite data feeding into your GPS receover contains no time zone data, it's just a raw time counter. The receiver must apply time zone rules separately to the data before displaying the "correct" time. Some do it, some don't, and many need updates as we keep changing the rules regarding Standard/Daylight time. GM/Denso? took the easy way out and left a big button on the nav to enable/disble DST.

Fortunantly I am right.

Yes, you are correct. Cell Phones and GPS units handle time differently.

Cell Phones obtain their time from a tower located in the area in which you are. Hence no need for a DST setting.

GPS units obtain their signal from a satellite and the satellite knows where you are located. My Garmin (255W) changes time based on which time zone I am located. My wife’s Tom Tom also changes time while driving thru different time zones.

In both cases there is no need for a DST setting.

Refer to Southern's post for an excellent explanation.

My Cadillac DTS unfortunately does not have the clock in the NAV system. It is an update I am not willing to pay for.

The latest NAV disk update...updates the firmware in the NAV system and adds the clock to the bar, at the top right hand side.

Southern's list is interesting but far from all inclusive. As far as I can tell, none of the Garmin units I have are on this list.

Then how can you say (in a previous post) that no Garmin’s set the time automatically?

Also, MacMuse’s post is absolutely correct.

Hey Jim, how YA been doing? We haven't communicated in awhile.

I know about the NAV clock update, I just do not want to lay out the bucks for a digital clock and lane feature at this time. I think I will wait till next year and take advantage of new features they offer at that time. I currently only have 26k on the 2006 Performance at this time so I’ll have her for awhile. I just retired through a layoff so will only use her for semi-annual trips. NJ-MN-VT (thru Canada) - NJ to visit grandkids, not their parents. However I’ll use the SUV and my Garmin going thru Canada in December this year just because of anticipated weather and the SUV has AWD.

And, as you always say (Darling wife) does not care, just so long as we do it.

OK. Only the the Garmin units that I have don't set DST automatically. I don't know about any other units, Garmin or otherwise. However, I have had five Cadillacs beginning in 2004, all with the Naviagation system, and none of them set DST automatically.

We are doing fine.
We are actually on another road trip at this time. :cloud9:
My 2006 already has over 72,000 on it...and this is my 2nd one.
The first one burned in my garage fire, with over 40,000 on it.
As you can tell...we travel a lot, and it is usually to unfamiliar places, so we use the NAV and OnStar a lot.

Sorry to hear about your (forced) retirement...that ia unless you were ready for it and are now enjoying it. :D

If thats the case...then "CONGRATULATIONS" :cloud9:

I might add, again, that setting the time and setting DST are two different things. While many GPS units will correct the time automatically when going from one time zone to another (mine units do this), it makes no sense to try and provide an automatic DST setting. These units, including the cars are sold all over the world. Some areas of the world, particularly those close to Equator, don't even use DST. Another example is Arizona (not close to the Equator) which does not use DST. Parts of Indiana used to not use DST - I don't think that is true any more. Parts of the world switch off and on DST at different times. Some parts of the world off set their time by 1/2 hour (Venezula and India) rather than the normal one hour. Taking all this into account would be a programming nightmare. Most GPS units, I obviously cannot speak for all, don't even try. They have a DTS setting that advances or retards the time by one hour if it is manually activated. Areas that use a 1/2 hour offset would be accounted for by manual setting of the time. And, last but not least, the date that areas go on and off DST is changing all the time.

I don't "CARE" if it is DST or not...
When the time changes...or when I go to another time zone...which I do quite often...it is less than a five second job to push three buttons and set the time to whatever I want it to be.

Setting the time on a Cadillac DTS NAV system is super easy.

My "ONLY" comment about DST was, that it would have been nice "IF" it was integrated into the NAV system.
Since it isn't...so be it.
I am not helpless...I will just change it as needed.

I took a trip last week and changed it twice...once going into Mountain Time...and again coming back to central time.

It is so easy to change...it should never be an issue for anyone.

GM Denso units don't have a correct time setting for Alaska Standard or Alaska Daylight time. Fortunately I can tell time and I can set the correct time manually.

EXACTLY...

Thats what I do also.
Just set it and be done with it.

:cool2: :cool2:

Just so you know, Alaska uses Pacific time (same as California) and does use DST - although it is not on DST at the moment. If you are looking for any settings in the Nav unit that refer to Alaska, you will looking for a long time (maybe forever).
