If the map has it in the data they show up. I have found its wrong on some roads. It will show 45 where the road is 35. It has allways worked on the instate for me. Two lane back roads roads not so much.

 

these speed limit on tom tom are incorrect most of the time in NYC , if travelers follow them, tons of local speed camera tickets will be in the mail.

 

interesting, has never shown up for me yet. I'm in a somewhat remote part of AZ, but it worked on my previous car, and my Miata.

 

My 2020 Outback limited has it but my 2024 Onyx does not.

 

Mine sometimes shows speed limit most of the time, sometimes not. But it works rather consistently. And it's occasionally wrong. There are no settings that I'm aware of to turn it on or off.

 

You have to choose it with the buttons at 7 o'clock on the steering wheel if I understand your question.

 

Hi,
My 2023 Gen6 German model depicts the speed limit; I think there is no way to disable this feature or to turn it on respectively.
The limit is not taken off the map data, but read off the signs via Eye Sight. It works far more than 90% of the time correctly.

 

I don't believe this is the case in North America. The 2021 and 2023 NA owner's manuals say the speed limit indicator will be shown "...if equipped". As Eyesight is standard equipment, it can't be the source for this information. The only optional equipment that makes sense as the source is map data from the nav system. This agrees with what I've read/seen in other threads on this site. Does the European manual indicate that Eyesight is the source for this information?

To the OP: in cases where you don't see the speed limit displayed, what is shown on the nav system's map screen? Is the speed limit shown?

 

Speed limit? What's that? 🤣

 

With the 2.5 NA definitely no concern.

 

@mangosmoothie; Our 2021 Touring has the speed limit display on the center readout; as previously mentioned, it is one of the screens selectable by using the control below the left center of the steering wheel. Some roadways will not display the speed limit and some are displayed incorrectly, but the display does work.

 

More I think about it there is a speed limit that sometimes, but not always, shows up on the left side of the center readout display. It is not the cars speed display that is selected by those controls. What I can glean from the web is that this speed limit data comes from the Tom Tom map data. Some say updating the maps helps. Can't find anything about it in any of the four manuals.

 

Even with Apple Maps in CarPlay it doesn't always show. But it differs between the various map apps. Waze may have it shown while Apple doesn't have it on the same road.

 

I was having problems with nav loading. I reset the infotainment to factory settings because I was also having issues connecting my phone.

Displays now! And Tom Tom loads right up. Must have just been buggy

 

It looks like a highway speed limit sign, right?. In the US, that information is based on the car's GPS and its map data having good information about the posted limit where it thinks you are. It is not based on what the cameras see, as it often changes the dash display where no signs are present.

If it does not display, it may not be equipped, or you could be in a place were it has no earthly clue how fast you are allowed to go and so it shows no information at all. Or, apparently, may need to be reset. I had some interesting experiences learning about this feature while test driving, as many modern cars have some version of it.

I've found it mostly useless around here. It's often incorrect, slow to update to my current point on the same stretch of road with varying posted limits, or thinks I'm on an adjacent road with a drastically different limit, and never shows any caution speed signs for sharp curves or blind hills. In contrast, the GPS map displays my correct position, heading, and the posted speed correctly most of the time (though I've seldom used it, since I usually already know where I'm going and the many possible ways to get there).

 

I don't believe the EyeSight systems reads the U.S. speed limit signs. As people have said, speed limits must come from the cars navigation system database, using GPS location data. In my case, there are places with no speed limits signs or the the sign is missing and a speed limit sign (white rectangle / black text) still shows on my driver display. There was no speed limit or any other signs for EyeSight to "see".

 

only option with Nav will show the speed limit on the dash, is not from the eyesight. if need to keep an eye on speed limit, use google map, waze or apple map is more accurate and update. the tom tom base nav is suck

 

We have the EyeSight/speed limit sign thingy in Australia. Works well, is handy.

 

agreed, I don't know if it is enabled in the US but over here my Outback has map data but it doesn't use it for the speed limit on the dash, which is GOOD. Cars that use map data were wrong so many times like how despite passing a sign that says "60" it'll say "50".

Only times I think it uses map data is for school zones, where it shows both the school time and normal speed limits. Surely the American cars with the newer eyesight have speed sign recognition. Subarus in Japan even have traffic light recognition.

 

I cannot speak for the in-car navigation, but the limit signs on the Waze (phone app) is dead on. I have monitored it on non-limited access highways where the roads (2 and 4 lane) pass through towns and school zones and have yet to not have them change as the limit changes. Now depending on your speed over the limit, it may be late, but at the limit it is on time.

 

Mine appears to work off the signs… At least it always changes at the very moment I pass a sign… But, for all I know, it could be deadly accurate GPS. I never use the system in the car.

 

Same for me. The moment I pass a speed limit sign on the side of the road, my display changes. I thought it was magic. 😀

Your areas must be pretty well mapped and updated in this regard, it's definitely off the navigation system database...

 

it's definitely off the navigation system database...

Good to know and I assume most of NY and the Northeast is mapped to a high degree of accuracy. I get speed sign indications in most places and they are dead on "just as you pass the signs" accurate.

Both the 2022 Audis (S5 Cabriolet and Enron) do a host of other road signs . . . . the technology is improving exponentially.
