Garmin Nuvi 3597 Observations

 

My family and I are on a road trip right now. We left the St. Paul MN area and are currently in Kentucky. I have noticed a few interesting things so far,

-Temperature: I have noticed that the temperature displayed on my Nuvi, Dodge Grand Caravan, and smartphone all seem to vary by a few degrees. Not a big deal, but I find it interesting.

-Speed Limit: On I-94 in Wisconsin, City Navigator seemed to display 65 MPH most places, but the posted limit is 70 MPH in most of those places.

-Time Zone Changes: The Nuvi displays the local time zone arrival time. I find it interesting when I have about 60 mlles to travel and it shows my arrival time in 1 minutes when there is a time zone change involved!

Your Nuvi gets temperature

Your Nuvi gets temperature from some internet source which could be off some times whereas your vehicle's temperature display could be more accurate.

Secondly, Speed limits variation can occur because whenever they did speed limit survey may be at that time there different speed at that time. I have seen issue in my area. Few roads were under constructions and speed was reduced on those roads but my Nuvi still shows that reduced speed.

Third issue could be a bug. You may report to Garmin. I think you should be able to report speed limit issues as well.

Weather and temperature are sent to the unit through the smartphone app so it's as current as the local weather report done hourly.

Speed limits and the displayed values are as you described, based on the last time a mapping car was through the area or reported by the local government. Speed limits are set locally by the local road department and are in accordance with both state and local ordinances.

Thanks for pointing that out. For some reason, I thought that temperature would be continuously updated, but knowing that it is only hourly is good to know.
