Why Is There No Head up Display (HUD) That Comes with Road Speed Limit Warning System?

I have been researching on internet since last 2 days trying to find myself a head up display (HUD) unit for my 2016 vehicle that will also alert me of road speed limit. Found heaps of HUDs with speed alarm system where 'you' need to set a speed limit which is not very useful as we have variety of speed limits on various roads. I found one of Polaris which alerts the driver with speed camera and red light camera which is awesome but still lacks the road speed warning feature.

Am I asking for too much from a non-intelligent HUD unit which is meant to just project the vehicle speed on the windscreen? Please suggest if there is something like this in the market or I should patent this idea? :)

    Some cars have this feature built into them.

      yep…buy a new volvo and you will have the feature

        and a hat. lol

      • And a speed governor.

      • or a Corolla

    Hi,
    If you have a Smart Phone you can project a HUD display using an Add-on feature of

    • This is an innovative idea for a phone app! I do wonder how well it would work during the day and also how you secure it to be legal in NSW.

    Why not just use Waze on a phone in a cradle in the ac vent it has all these feature and live traffic.

    • +3

      The purpose of HUD is to be able to look only at the road and not even have to look at the speedo. With smart phone in the cradle you are looking at road, speedo and the smartphone, totally defeats the purpose of HUD.

        The Waze app has the Speedo and the speed limit, have you just got licence?

        • +2

          Yes, and the head up purpose is not anyway solved by the phone in ac vent cradle.

            @CuriousMeerkat: You can attach your phone to your wind shield to either the centre or the right side. Head up displays are not that useful to be honest. I have it

        • Waze was only just added to CarPlay.

      • There’s an alert sound on Waze when you go over the limit.

    no need for a spoken speed alert you just look at the road and you'll see the speed signs?

      Not all roads have speed limit signs. I know one road is 60 and only has a speed camera ahead sign. Its only after camera do you see it at 60. Looking at phone or HUD would have been helpful to check the current limit.

      • Where is that?

      • The app isn’t necessarily correct either. My loan car (Subaru XV, with this speed sign thingy) during servicing had three discrepancies during the 10km drive home where the speed had been lowered on those roads.

      • but doesn't most states say if its a built up area with no speed limit consider it a 60 k limit if outside a "built up" area the speed is considered 100 k?

      Oh look, it's the 'I can't personally envision a need for it myself or a situation where I would need it so therefore 100% of the people in existence won't need it' brigade.

    The best heads up display is the white sign with a red circle. inside that red circle is an unquestionable number.
    It is visible within a good 50m and it's very reliable.

    I would give that a go first.

      Sorry, but everyone seems to be missing the point… the use of head up display (HUD) is to display my vehicle speed on windscreen and I don't have to look down at the speedo while driving. Yes, there are road signs for speed limit but an additional help from the HUD is handy.

      World was able to navigate in the past just following the road signs without the GPS but that did not stop the world from using GPS when it became available readily. If you see what I mean.

      • No. I don't.

        The Sygic solution (above) provides a HUD to Windscreen via your Mobile phone by projecting your vehicle speed to said Windscreen.
        It isn't mounted in any cradle or Cupholder.

        • +1

          Looks good but only works at night by the look of it

        • I tried the Sygic solution, has many problems:

          1. Works only at night, could not see anything at all in the day
          2. Very hard to keep the mobile on the dash with no means to secure it in one place
          3. Keeps the mobile engaged, Not able to use it for navigation
    • That would require you to have your head up and facing the road tho..

    Honda civic has this, big pretty digital display just above steering wheels visually (not on windscreen). However, will not inform you of speed limits. You need some kind of separate app for that kind of update info- not sure about new models though.

  • The new Mazda 3 has it, plus they need to be updated, and still some are the wrong speed limit. If you don't want to fork out for a new car, then the iGo Navagation App (non HUD) on your android phone, the Navman Micam (GPS and dashcam in one, non HUD) , and possibly many other GPS units out there. These are just a few, many GPS apps on your phone support HUD, not sure about speed limit though.

  • Many new european cars have this built in. They recognize the speed limit sign and show it on your screens and alert you when you go faster. Can't remember if they projected any info to HUD too.

    • Hardly a European feature these days, a lot of cars have traffic sign recognition and if they have a HUD will flick it up there too.

    to answer the question in your post title, firstly the data just isn't there to back this sort of thing to a level of usefulness, but in reality at the end of the day the thing that kills it is "ignorance isn't innocence" this type of product would have to be plastered with so many warnings and disclaimers making sure the product isn't legally liable for someone speeding and to make sure the user is starkly aware that despite what the hud says the actual signed limit at that exact moment in time is law.

    Despite having a lovely digital number telling you the current limit maybe even flashing red if you exceed it at the end of the day you are going to have to be just as aware of the current limit as if you didn't have the HUD anyway, the go to thought is "but it could alert me if im going 111 in a 110 zone" but what happens when it thinks its 110 but its really 80 and its giving you a calm warning whilst being 31 over the limit

    the perfect scenario of a 100% upto date dataset sure but that isnt reality and as soon as it doesnt know one road it might as well not know any, which i imagine is why most products settle for "you tell us the limit we will warn you"

    • open street map has a pretty good openly licensed dataset. Not 100% reliable, or 100% coverage, but a useful extra clue to what the speed limit currently is when you haven't seen a sign.

  • you know you're meant to look at your dash for other things, not just speed, when driving too yeh?

    Yes you are… the entire system runs from your vehicle's own electronics

    Why is everyone ripping on OP so hard? He asked a simple question, not should he use Waze or whatever other options there are.

    He specifically wants a HUD. unfortunately they don’t make a HUD with the features he would like, that’s it. Nowhere did he say he would solely rely on it for speed limits, nor did he say anything about being unable to read speed signs.

    I’m all for a good troll, but seriously?

      I agree with you there - I thought it was a good question! Ozbargain seems to require putting sh@t on people for almost anything (yes, now including my comment…)

      Posts about any issues on the road do not go down well here. Australia is full of holier than thou Ned Flanders types who love nothing more than saying "told you so" and "just follow the rules". Pointless arguing with those types. Just ignore them and move on to an actually helpful answer.

      • +1

        I probably wouldn't say "Australia is full of".

        Ozbargain however has quite a few of those characters.

  • Mazda has this 2019 cx5. HUD display also "reads" road signs and displays on HUD, for example going through construction zone.
    Based off IGO maps.

    There are two types of people:

    • those who appreciate HUDs
    • those who haven't driven a car with a HUD before

    As the previous poster said: I believe many recent cars with advanced driver assistance features have speed limit reading.

      Thts truly fantastic. No need of large memory space to hold road information, just scan the road in run time and display it on the HUD.

    Have you considered checking that dial on your instrument panel called a Speedometer???

    They come standard with all cars.

    Also a standard feature with warnings on most GPS

    Given the speed limits can change very km or so its pointless in a HUD mate!

  • How is the HUD supposed to know what is the speed limit on your current road? To do that it needs to have some sort of GPS tracking AND access to maps that contain road speed limits. After market HUDs probably have neither of these.
    The Mazda CX-5 has a HUD with this that's linked into the built in navigation and is a big reason why I'm getting one! Kia Seltos also has a HUD but I can't remember if the current speed limit is displayed on it.

    • Yes, for the kind of solution I am looking for, it needs to have same info (road speed limits) as that in a sat nav. It also needs to have GPS tracking to track the vehicle speed.

      Alternatively, it could be just a hardware system like https://www.ebay.com.au/itm/363110580567?ul_noapp=true, which will be connected (bluetooth) with phone app to display road speed limit as well as the car speed. Additionally it may also display warning for speed and red light camera.

      Yes, I heard that CX-5 comes with this kind of HUD unit which is integrated with the internal navigation system.

  • Learn to watch out for the road signs instead?

  • Mazda CX30 has it, reads the signs and displays on the HUD. More importantly works rather well.

  • My wife's car thought it was 110kmh limit in a 60 zone the other day. Seems like a very helpful feature.
