Anyone having issues with the traffic sign recognition?

Was driving in a 30mph road and the traffic sign recognition displayed a 70mph :roll:

When I drive into the car park at the gym the RSA shows me entering a motorway! The logo on the welcome sign to the gym is vaguely like the motorway sign~ but only very vaguely.
😱

its not fool proof told me speed on motorway should be 100 mph

Switched it off after a couple of days. Too many incorrect signs. Especially when signs contain of 2 parts: only for trucks, only when raining etc.

I prefer the signs on the nav display

I leaned to see the signs myself and not rely on the signs shown on the RSA or navigation!

Its a nice gimmic but the RSA can make mistakes (no sign, dirty sign, a bit hidden sign, look-a-like sign, etc.) and maximum speeds can change.. your navigation will know that at least 1 year later after update.

For some reason the RSA sometimes decides to recognise the limit signs in KPH, even though it's never left the UK. No pattern.

How do you know it is km/h? RSA only shows the sign on the small display without units.

It changes color when you exceed the speed limit

If RSA recognized 70 and speedometer shows 70, no matter what the unit is, the sign on display would not change color.

Ahh.. I see what you mean and you're right ;D

Today as I drove into a 40 MPH zone, it went from a white 40 in a red circle to a solid red sign when I was doing less than 40 MPH, but more than 40 KPH

It is definitely reporting MPH signs as KPH occasionally.

Does it show mph on this screen?

 

[Karmalakas]

Speedometer seems to be in km/h. But you switched display to miles, right?

I have noticed if it's 30 MPH it will not show between the speedometer and rev counter but when it goes to 40 mph and above it will.

So it works like the manual said (page 304)
● When the vehicle speed exceeds the speed warning threshold
applied to the speed limit of the sign displayed on the multi-information
display, the sign color becomes inverted.

Page 306
● When driving vehicle in country with different speed unit
Since RSA recognizes signs based on the set unit of the meter, it is necessary to change the set unit of the meter. Adjust the set unit of the meter to the speed unit of signs in the current location. (?P. 679)

Depend on the treshold that is been set (e,g, 2,5 or 10)

My car is correctly set up in MPH. So my digital speed display shows in MPH.

The recognition of the signs itself is never in question. What is in question is when it inverts the symbol to tell me that I'm exceeding the speed limit, even when I'm not.

The best example I can talk about is a 40MPH zone on my way to work. 9 times from 10 I can pass that sign doing 40 MPH and the speed limit display is fine. That 1 time though the RSA will read the sign as a 40 and show 40 on the dashboard, but I'm doing 40 MPH and it goes red as though I am speeding, but if I slow to 40 KPH it shows the normal not speeding sign.

Also, I notice from your photo, miro that the KPH dial only shows KPH. In the UK the dial has the MPH number bigger, but the KPH is shown too. I'll see if I can post a photograph.

I have set the offset to 5MPH because in the UK our speedos tend to be calibrated to show a slightly higher speed than we're travelling - so 40 MPH indicated is only 37 MPH real world. No idea why

To be fair though, this is nothing more than a niggle - I know what the speed limit is when I'm driving - it's just frustrating that it appears to work inconsistently.

EDIT: Time to get the duster out!

I changed the units to mph and mpg to show how SpaceCoyote's digital speedo should look like. My dial with the needle on right side is in km/h.
It is odd how your speed limit warning works with your settings SpaceCoyote. Contact Toyota dealer for a solution.
P.S. Cars made with km/h do not have mph on the dial as imperial marketed cars have. I was traveling to London with my avensis before 2 years and had no idea if i'm in the speed limit. After leaving the euro tunnel i took the left lane together with the slowest traffic hoping i will not get a fine. UK should change units and driver position

UK should change units and driver position

No - we got it right. It's the rest of you that are out of step!!
