Speed limit display for many interstates and highways on Nuvi 760

As far as I can tell, it isn't user changeable. It just works, if the data is included for that road in the database. It works well for me in the US. Can't say about Canada.

The speed limit display disappears when you cross the border into Canada. I drove across the US this summer and really liked having the speed limit displayed. Hopefully, they will implement it for Canada on the next map update. Simulate a route in the US on your Nuvi (choose an Interstate Highway since some lower order roads may not show the speed limit, although I found most did) and you will see the speed limit.

For our 1500 mile trip from Mass to south Alabama, I was very pleased with the performance of my 880 and speed limits. My husband as navigator would spot a sign along the highway and immediately check the GPSr for an update of the speed. In 9 out of 10 cases, it changed as we drove by the sign. The only times it did not change was for the temporary changes in speed posted around construction areas.

In the states the sign will show when they have data. Using the 2008 maps I only saw interstate speeds, but using 2009 maps it now shows many city streets, 30 and 45 mph. Most are very correct and usually changes within a couple feet of the sign.

I am getting speed limits and so far accurate readings for streets in Pasco County Florida.

While driving on a road with varying speed zone, the gps (255W) would literally update the on-screen icon as I passed the road sign. Not every street has the info. But when it's there, it's really cool.

my 255w does that too,i dont know how but mine is within 10 feet of the sign,thats pretty darn close

I found this exceedingly useful when driving around Florida, earlier in the year. Speed limits seemed to change frequently (for no apparent reason!), and I quite often didn't notice the roadside signs. (Here in the UK, the signs are a lot more prominent - as are the fixed Speed Cameras that often go with them )

As for it working in Canada, it's just a matter of getting the data into the map, which obviously takes time. The City Navigator Europe V2008 maps only really contained speed data for the motorway network (which wasn't very useful). The V2009 maps extend this to most of the major roads and some of the minor ones too.

I found this is very useful on my "new" Nuvi 770. Only one section of my neighborhood road has unmatched speed limit. I am wondering if this data can be included in traffic alert signal so it can be updated when posted speed limits are changed.

The speed limit data cannot be updated via the traffic receiver as it is embedded in the road classification within the map data. It can be updated though when you update to a new map version.

Is this feature available for all units like the nuvi 350 when you get the map update. If so, this may make getting the map update worthwhile. Mine is over 2 years old but still see very few errors when I travel in Texas.

I haven't tried, this, as I am far away from Canada, but I WONDER if maybe to get this to work for highways in Canada you would need to change your unit of measure to metric, since Canadian speed limits are posted in Kilometers.

It might be worth a try, the next time you are on a Canadian highway.

For the user that was traveling from the USA into Canada, doesn't Canada use Km? I'm curious if that makes a difference in that if you have your GPS set for MPH and enter a country that uses Km. I should head to Europe with my 770 and check it out.

For those wondering about km speed limits....

I-19 in Arizona between Tucson and Nogales has speed limits in km, I'm wondering if any members in southern Az may be making a trip to that area could check it out and report back how it is displayed?

Speed Limit Display does not work in Canada with Garmin and Navigon units

Only units listed as compatible with that feature (7xx and up along with "T" models I believe) can use it even though the data 'might' be in the mapping software.

When you have questions about what features your 350 supports you can always go to Garmin's website. There's an online list even though your model is discontinued: https://buy.garmin.com/shop/shop.do?cID=164&pID=31655#specsT...

Most are correct here in the Dallas area. The ones that do not match are at least 5 MPH under the actual posted limit. So, at least it's not telling you that you can drive faster than the posted limit in that area. The only strange one was on I-35E on the north side of Denton, TX. It showed the speed limit at 50 MPH. We haven't had a 50 MPH highway speed in years. The minimum is 55 MPH and that particular section is actully 65. That was the only one that was way off.

It's still a neat feature!

I too enjoyed the speed limit sign while driving to Florida last winter. One thing I would like Garmin to add would be an audible warning when you drive over or go over the posted limit. This could save $'s on traffic tickets. An option to turn it "on/off" should also be included for obvious reasons.

I have the nuvi 205 and it displays speed limits and I would like tha feature of having an alert, with the ability to turn it off/on

Garmin can do it if they want to. Navigon offers that exact feature. I have the tiny N100 shown here: http://www.buy.com/retail/product.asp?sku=204389909

You can set the threshold you want the GPS to allow over the posted limit before the warning is issued. I.E. if you set the alert to notify you when you're going 5 mph over the posted limit you'll hear and see an alert as soon as you hit 40 mph in a 35 mph zone. If Navigon can do it, certainly Garmin can.

Cheers

A company has to think long and hard about that one. Are they going to pay your ticket if the info was wrong on the map, and you didn't get the alert. I don't think so. I agree it would be nice, but I don't look for it.

That's why the in-dash factory GPSr on my Toyota does not allow keyboard entry when the vehicle is in motion. I am like a fool paying so much and get less.

Yes Canada uses km, but it doesn't affect the display of the speed limit info. Unfortunately, the signs don’t display in Canada (yet). Interestingly, if I set my Nuvi to km/h, the speed limit signs still come up in the US, but with a number converted from mph to km/h i.e. a 65 mph speed limit will show as 104 km/h. Even though I live in Canada, I keep my Nuvi set to mph and still calculate my mileage in miles/gallon etc. Some of us of a certain age are still much more comfortable with the pre-metric system. Hard to believe we switched over more than 30 years ago!

The whole point is that the Canadian portion of the Map Database hasn't been updated to include the speed information like the US portion has. That's a lot of expensive detailed work and verification.

Look for it in future Map upgrades.

Thanks all for your input. We will wait for this feature to work in Canada some day.

If you're that worried about driving over the speed limit then perhaps you should use cruise control on your vehicle?
I know I use it.

I do use cruise control to make sure I do not exceed allowable speed limits in major interstates. However, it comes when speed limit changes in different sections on same route, say, going to a small town where posted speed limit is set to "15 mph" where police activities were reported. I feel this feature would be helpful.

No, they use MPH on I-19 just like everywhere else in the US (although KM/H may also appear on the signs). What you may be thinking of is that the exit numbers are based on kilometers instead of miles, and distances are signed in kilometers instead of miles.

Another road that uses kilometer-based exit numbers is Route 1 in Delaware, although all other signage on the road is based on miles.

I would like to see them implement something that either changed the color of the speed indicator(less intrusive) or gave an audible alert when you current speed was over the posted speed (if available). Is there a place to make this suggestion to Garmin?

Like all things in the commercial world you go where the money is. The numbers of units sold in Canada is far less then the USA. As a company the critical mass is in the USA and therefore that is where the money is spent. They have included Canada maps details because it allows them to sell to Canadians and is a benefit to some Americans traveling north. Don't expect Garmin to add too many features just to benefit Canadians.

my 255w has been accurate posting the correct speed limits here in il. too.very pleased
mike

You can simulate a route and see if it works OK in USA-- I was surprised that my new 5000 has this feature and it is worthwhile. There were many times in my previous travels that I was concerned because I could not find a speed sign. Hope the NUVI 5000 will save me a speeding ticket.

I was coming home with my new toy today and noticed the same thing on my 255w as well - Rather impressive on the advanced programing of these things.
