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.

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 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.

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.
