Speed limit

I haven't noticed this feature in any Garmin models (but I haven't really looked for it either). I have seen a few other GPS brands that have a built-in speed database that will warn you if you're going faster than the posted speed. I haven't had a chance to use the feature personally, so I don't know how well it works.

So far, I haven't come across any downloadable files that have this data. The data is probably most useful when it's associated with road segments. A POI database would only identify speed at a particular point along the road.

The Mio C310x has a setting in it for Over Speed Alert. You set up the average speed limits in the unit and then set up the alert to warn you at certain intervals. On mine I have it showing the average for highways at 65 mph, then an alert to go off at 80 mph (well, 15 over is my default alert regardless of the settings for average speed).

The unit has a "fast flyover" feature that allows you to test your route, starting on side streets at 155 mph then highways at 345 mph, and I have to chuckle cause the over speed warning goes off when doing the fast flyover...lol

The garmin c330 doesn't have it though you can do something similar. You can create custom poi that have a speed limit attached to them and whenever you are close to the poi it will warn you of the speed limit and if you go over that speed limit (that you set) the gps unit will start to beep and flash a banner on the screen warning you. This would be good for speed traps around places you normally go.

There are some pay sites for GPS speed limits
I think Garmin has one. I'll check my Gps and get back to you

Garmin 2720 has it

i was looking at trying to incorporate the speed warning feature in my c320.. i came across your post and was wondering if you could provide some more information..

thanks

On my Mio 310X It knows the speed limit of most streets and highways, and displays them. They are pretty accurate.

On one street, the speed limit changes from 35 to 40 mph. The Mio speed indicator changes as well, within 10 yards of crossing where the road sign is posted.

Mio also has settings where you can indicate if you want to be notified when you are over the speed limit, and by how many mph over you want the alert to sound.

I would like to find out how to use this feature on my 2720. I have not seen it in the manual.

I wish there were some way to do this on the nuvi 660. I think we could do it with a gigantic POI file but it doesn't seem to exist, and anyhow would probably take 10 hours to load if it did.

I see the speed limit on most "major" highways, like freeways, but have yet to see it on "surface" streets, country roads, etc., even the more major non-freeways (US & State hiways, e.g.). This would be in the Central Ohio area. - Gene

Would like to know how to get the speed limit warnings on a 2720. This is my first gps and I'm trying to learn everything it will do and how to do it.

Your Garmin 2720 has this feature here is how you get to it For adjusting custom POI Alerts go to menu touch settings then general then touch proximity Alerts then touch continuous notification all alerts and then select all alerts ok to turn them on or turn them off hope this helps you also if you go to garmin and download the PDF Manual for the 2720 it has everything in it and it is free from Garmin

JM the Garmin 2720 has this feature just so you know here is how it works.........Your Garmin 2720 has this feature here is how you get to it For adjusting custom POI Alerts go to menu touch settings then general then touch proximity Alerts then touch continuous notification all alerts and then select all alerts ok to turn them on or turn them off hope this helps you also if you go to garmin and download the PDF Manual for the 2720 it has everything in it and it is free from Garmin

I noticed the 360 shows the speed but dont know if a file exist to give an alert when going above the posted speed limit.

Thanks Auggie, I need all the help I can get. Bought the 2720 to use on a Harley to travel with. Trying to learn how to use it first.

Does anyone know where I can download POI's for speed limit? So when am going through a speed limit area would sound. Thank's

The LG unit has that option which my wife loves...at least it keeps me at bay when I do go over the speed limit at times. I find it exceptionally amazing on how this and few other GPS models do know the speed limit on any given road.

A useful tool to have if anything.

On any given road, if I drive over the speed limit by even 1 mph, the voice activated feature will warn me I am driving above the speed limit and will continue to do so at 10 seconds intervals.

Thank you so much!!

Nüvi 750 has it for Interstate highways. An icon shows up at the left edge. A(n un)pleasant surprise.

The icon adjusted to the posted speed limit, disappeared when I got off the Interstate onto U.S. Highway, and reappeared when I got back on another Interstate.

Ok, two things...

1) the original post as about speed limits of the road, not of the vehicle. In other words, the author wanted to know what the speed limit of the road is, not setting a threshold of the vehicle's speed limit.

2) As far as I know, no Garmin except for the 7xx series gives you the above ability.

Correct me if I am wrong. I wish that all GPSrs was able to show you the speed limit of the road.

Ant the 750 is limited to inly a few roads (like freeways).

For the route time calculations I believe the unit uses a generic speed for all roads of a certain type, which may or may not match the actual posted speed limit.

Hi,

Is there any Speed limit CSV available for garmin 200 NUVI?
It would be great if someone can please let know the link.

Thanks,

I guess we still have to stick to the old skool way of determining the correct current speed limit.

Therefore the LN740 is the only unit out there that knows the speed limit of all the roads? I find that somewhat odd.... I live in Montreal QC, and I do extensive traveling. I have not found any errors as of yet in which the unit is consistently accurate in telling me I am driving over the speed limit regardless of which road I am on.

I wanted to jump start this topic again. Does anyone have a Gramin unit with speed limit warning? I heard my cousin's year old Navigon GPS had the feature. I was wondering if any of the newer 2010 units have this feature.

Has this feature (with the latest firmware update installed). It displays the current speed limit and the current speed display turns red when you exceed the posted limit.

Here's a link to how it looks on the 1690:

Of the current nuvis, it looks like only the 1200 and the 1300 do not offer the speed limit display:

I bought the 1300T yesterday out of necessity. My 255W was stolen so I needed something quickly for my job. I "upgraded" to the 1300T because it has Lifetime Maps and Lifetime Traffic (ad supported to my chagrin). This was a snap decision made in-store so I had no idea I needed to look for the speed limit feature. For crying out loud it was on the $120 255W.

Not only was the speed limit very accurate in my area, but this was the only reference I used for a couple of years. The speed limit sign beside my actual speed is a very quick glance to know I was within my boundaries. The speedometer was rendered useless. Yeah, I can still get my speed off of this unit, but I am clueless to speed limits when I go into new areas and don't want to have to think about it.

This is really no different from having to think about where I am going. Just follow the GPS route and I am there. What a stress reliever. Now I have to be on constant alert looking for speed limit signs after getting out of the habit. A new layer of stress on an "upgrade" model. This is enough that Garmin has lost my trust in the future and I will look at other brands first.

This feature has to be available on these models! How else can they calculate ETA? It is nothing more than making these units show it graphically. There has to be a way to activate this. Any suggestions ... any at all? Thanks

Wikispeedia.org is amassing a database of the locations of all the speed limit signs in the world. I have not figured the site or the system out yet, but they do have noble intentions.

OK, that's just weird. And crazy??
Looks like it's most helpful when you're in Tierra del Fuego.
I suppose it would make a great & inevitable compliment to OSM though.

But kinda geeky-kewl in a twisted way. They should concentrate on how to suck the data out of the existing Garmin maps if they want to tackle the U.S. though.

Reminds me of a funny story when I first got my gps. I was showing my wife how/where it had the speed displayed. She noticed that it changed almost exactly when we passed a speed limit sign & asked how it 'knew'. I said 'a huge database'. She didn't believe me and was (still is?) convinced that there was something on each sign transmitting to the nuvi.

Sweet girl. I gotta keep her.

**EDIT** Not so odd anymore, since I found this by clicking (no, not More Info, but Add Your Project!)

Garmin displays speed limits for the highway you're on, as long as you're in the US. It does not display for Canadian highways.

It takes alot of extra little work to make this speed limiter happen when creating a POI file. Just keep that in mind as others have suggested.

While there are several features about my "built-in" I enjoy, I miss having the speed limit as on my GO930.
