speed limit (garmin shows the wrong speed limit for an area)

Speed limits change. The updates do not always get timely updates, as do roads. There is no company in charge of those. Speed limits are supplied by the local/county/state entities in charge of that area.

And please always keep in my that the GPS unit is a tool to ASSIST you with navigating. It is not an absolute. Never rely on it implicitly. And always follow the local signage. The database (whether it be roads, speed limits, or POIs) is NEVER going to be 100% accurate.

Some of the newer models allow you to touch the speed limit sign on the screen and edit the speeds.

Incorrect speed limits is always a possibility. It happens. There is no way around it. As has always been said, follow the local signage.

I too have had the problem. It is not always accurate.

That's probably the one thing I don't really pay attention to on the GPS.

I tend to watch for speed limit signs, look at my speedometer, and pay attention to how fast traffic is flowing.

I wonder how long before Garmin updates the new 70 mph speed limits? It is important because the new limit is not for all the Interstates, just some.
Like most people say, "Read the signs."

My experience with the speed limits displayed on my Garmin 3790 LMT, mostly as seen in the Albuquerque area but some elsewhere, is that I am more likely to be right assuming they are correct then assuming that my own best guess (not yet having spotted an actual speed limit sign) is correct.

While caution is certainly indicated and I have seen plenty of mistakes, I still think it is a useful feature. I also agree that it is no substitute for keeping out a good watch for actual speed limit signs.

In a lot of areas the government has reduced the number of signs posted to "save money".

Former guv Rod Blagojevich. (now in jail) put up lots of signs and replaced older signs with brand new ones. He had a "preferred" & exclusive vendor.

I too have found many mistakes on the GPS's speed limits. It is the version of the map that determines it's accuracy. So those using older maps will probaly have even more mistakes.

My 2460LMT has the abilty to correct any speed limit errors but I never use it, I want to concentrate on driving in a safe manner.

i have a Kenwood DNN990HD with Garmin navigation.The posted speed limits can be changed by touching the speed sign,once all your areas are set up your good to go.

I did that for a while, but each time a new update for the 2460 comes along the ones I corrected were back to the wrong limit. I don't bother anymore.

My 2557 has a few places in the area where it says its 55mph but it's actually 70. I hope the next map update fixes some of those errors.

--Uh-Oh!

I used to drive a stretch of country road every work day for 2 years. The stretch has variable speed limits that go from 55 to 25. For years my 760 showed each and every variation along that long stretch of road. The speed limit always changed on the screen when it changed on the road signs.

After one of the recent map updates that changed and the speed limits displayed on my unit were totally messed up. I don't think it's a Garmin issue. Whoever inputs the speed limit data for the maps was apparently asleep on the job or maybe drinking heavily...

Thanks for the info I was not aware of that feature on my unit

I have always believed (without evidence) that the basic GIS data is procured from a local government entity. You know the old jokes about the competence of government employees. Or if there are new speed cameras, you could blame it on "revenue enhancement".

I always wonder if that change is sent to Garmin when I sync with the computer.

I have 3597 but looks like I can not chage the spped limit on this unit.

Only a few, now older models, had the ability for user inputted speed limit changes. The 2013 models, like your 3597 does not have this ability.

You can update the limit by touch on it. At least I can do that on my 3490.

The speed limits are imbedded in the map, so they come from Navteq. I have found mine to be mostly accurate. Useful as a guide for when I don't see a sign close by. But I always look for a sign FIRST.

I'm thinking it must come from county data, at least here in Kansas. My 2360 does not show any speed limits in my county (even state highways with 70 MPH limit), but the minute I cross into the next county the speed limit shows up for the same road.

Agreed. I have been to a few places where no limit is displayed.

Some models allow you to make corrections yourself (what a concept) - but not mine...

That is why they are "employees" not "workers."

My Kenwood unit had to be sent back to kenwood for repairs,got it back in one week(quick turnaround)i thought.I bought unit in September 2013,Will get unit reinstalled and will then see if my speed limits change or stay as corrected.Once there is another update.Hopefully all is well now.

I have several garmin gps units. The only one that will allow me to edit the speed limits is the GPS for truckers.
I was greatly disappointed when I purchased a Garmin Gps for over $200. and I am un able to edit speed limits on this new one.

Now the New Garmin Truckers unit costs around $400,00. Out of my reach now. I am looking for a unit that will allow user editing of speed limits.

Another gripe. Load a route form home to a location, Get there and then push the go home button, and Garmin gives a different route.
It would be nice to able to edit the route when you know the GPS is giving a longer route. Even when It's tasked for shortest route.

I do not think price is necessarily the driver of whether a Garmin device has the ability to edit the speed limit. The ones which allow this are the nuvi 2200, 2300, 2400, 3400, 3500 series, the LIVE 2300 series, and dezl 560. It is just a feature of those units. I do not think it should be expected that every feature of every unit will be identical. If editing the speed limit was a feature you wanted, then it was your responsibility to determine that such was a feature of the unit you bought.

Thanks!
