Time Zone change.

The automatic time zone started back on the xx5 models I believe.Had my 265 almost 2 years and it has it.The 1390t also has it according to manual.See page 40 . http://static.garmincdn.com/pumac/nuvi_1100_1200_1300_1400_O... just have to make sure to select automatic.Tools,settings and time.

Thanks again!

my 360 doesn't switch and my 765t does switch zones

As Charlesd45 mentioned above, the xx5 models introduced this feature. Presumably the newest models include this, but I'd do the research before buying a new one if this was an important feature for you.

It seems like this was a long time coming since the GPSr could know where the timezone boundaries were and it knew where it was, so the rest was simple math when calculating a route that crossed timezones. Even the ability to adjust its internal clock when crossing a timezone is a relatively new function in a GPSr.

Will it turn the time ahead and back for the time changes?

Yes it will and the actual Time Zone file is updated periodically when changes to dates, boundaries, etc. are made.

It never did befor I updated the maps.
I thought I was going crazy.
I did not remember changing the time after the latest change, but it was right.

Returning from Florida, I had my 1490t and my 295w on the dash. Barbara watched her cell phone. As we passed the sign, the US Cellular changed the time. My 1490 changed just a few seconds later. The 295 changed about a minute later. My Trac-Phone changed about 15 minutes later.

Interesting.

Do you have any thoughts as to why?

How isolated was the area - ie # of cell towers, etc?

I-24 passes through some hills at the time zone line. I don't know if there are multiple towers along there. Both GPS units were tracking just fine. The Trac-phone is an inexpensive service and not for a frequent user. But still, it should have detected the time change more quickly.

Doesn't the cell phone get its time hack from the tower it is connected to? If so, the time in the phone wouldn't change until the phone is handed off to the next tower. Assuming the 1st tower was close to the boundary of the time zone, you might have to travel several miles into the new timezone before the next tower picks you up and it would be at that time when your phone's clock would change.

Since I've had my 855 all of my traveling has been north and south within the CST zone so I can't verify if it changes or not. I'll just have to take charlesd45's word on that.

I have a Garmin 1450 and it changes by itself,thank goodness.When the time change changed I just turned on my GPS and it switched to the correct time.

I have an 855 and I have to change the Time Zone manually.

Your explanation makes sense. The cheaper service, (Trac-phone) does not search for a new tower until it loses contact with the current tower. Barbara's service (US Cellular) may constantly look for closest tower.

My 255W automatically shows arrival "Local" time as well, even it is in a different time zone. This I learned the HARD WAY.

While returning from Florida to Michigan a week ago via I-65 through Nashville, I wanted to see what motels we might stop at for the night. I chose a couple of motels in cities along our route, and entered each as a "Go To" destination. I finally decided on one based on the displayed arrival time and called ahead for reservations.

What I didn't remember was that the clock in the car was set to Eastern time and the display on the GPS was showing in "Local" or Central time. The result was that I had to drive an hour longer than I had planned.

So remember, the GPS arrival time is in "local" time at the destination.
