Nuvi time zone adjustments

 

I formerly owned a Nuvi 780 units, which I believe relied on the MSN receiver for time zone adjustment. Within the past year I purchased Nuvi 775T and 1260T units which have built in time zone recognition without an MSN or traffic receiver. While I have traveled to different time zones with my new units, my routes have been all within the same time zone. In other words, I have not yet crossed a time zone within a route. I am curious whether the Nuvi 775T and 1260T units will automatically adjust for time zone between origin and destination in quoting the estimated arrival time for a given route. Example: traveling from Los Angeles to New York. couple of related questions: (1) if these adjustments I mentioned are all automatic on my particular units, which Nuvi product lines from Garmin have this capability, (2) are the time zone boundaries and DST adjustments all sourced from the map vendor (Navteq) and what are experiences with the accuracy of that data?

Very Accurate

There is a separate file that is stored on your Nuvi that contains the timezone data. If I recall an update to the time zone file was recently available via Webupdater. I guess that indicates that the data is separate from the Navteq map data but where Garmin gets the information from I'm not sure.

Our experience has been that the data is very accurate. We find that the time displayed on the Nuvi changes within a very short period after we pass the signs on the highway indicating that we have entered a new time zone. As I recall our Nuvi knew about DST back in March as well.

I believe that the 1xxx and 7x5 models are the only ones that have time zone data but the 8xx models may also have it.

Question: Does my nuvi or zumo automatically change time zones when I travel to a new time zone?

Answer:
The following series of units will automatically adjust your time zone while navigating:

nuvi 1000 series (includes 1100/1200/1300/1400/1600 series)
nuvi 205 series
nuvi 400 series
nuvi 705 series
nuvi 3700 series
zumo 660
zumo 665
zumo 220

The nuvi 200, 300, 500, 600, 700, 800, 805, 5000 series and the zumo 400 and 500 series will not automatically adjust your time zone while navigating. These units will continue to display the time in correspondence with the time zone that you selected when you set up the unit.

To manually change the time zone for your unit:

From the Main menu, touch Tools (wrench icon).
Touch Settings1.
Touch Time2.
Change the Time Zone option to the correct time zone.

*Note 1: The nuvi 300/600 series and zumo 400/500 series do not have the Settings menu.

*Note 2: The nuvi 300/600 series and zumo 400/500 series do not have the Time menu. You would need to touch Locale and then touch the time to adjust your time settings.

Good to know. I thought that all the units would do it automatically, since they all get their info from the satellites, but I guess the programmers didn't think of it when they released some models.

automatic time zone

I really like this feature on the 755T and wish my 855 had it.
