Is it possible that RSA will not work with EUROPE signs?

Rav 4 XLE Premium 2021 imported from USA to Europe.

If the European signs are visually different in shape, dimensions, and language from US signs I doubt the US model RSA will "see" and display them. The system is probably programmed for English language and US standard signs.

 

As a follow-up: The RSA (Road Sign Assist) and the Pre-Collision System (PCS) rely on the camera installed behind the windshield and rear view mirror to "see" objects. However the systems have software programming that allows a simple minded Artificial Intelligence to recognize what it is seeing. The PCS can only recognize a few things as explained by the attached screenshot from the official Toyota site. The PCS cannot recognize a deer, or a dog or a tree or a telephone pole. Similarly, I think it is safe to say that the RSA is also programmed to only recognize a limited number of specific signs. For example: you won't get RSA notices for random billboards, Burger King and fast food signs, or bus stop signs, or street name signs. Therefore if you take a US model RAV to Europe it is not going to recognize any sign that is not in English, or that has a shape and size not used in the US.

 

Had a buddy that did opposite... Europe car to US.

The RSA only worked randomly and no amount of "pestering" domestic manufacturer helped.

 

So the question is.. Should I bother about that, since 99% of the time I drive with AndroidAuto connected and waze..
And to fix that it will (most likely) require to flash the american version of the software and replace it with the European one, using some hacky tools.
I remember some time ago, when I was flashing the bios of my old computer, the process died and my computer was not longer booting, so I needed to reprogram it.
And this one looks very similar as an approach, therefore - why to risk for a something which is not a big deal.
The same applies to the radio working on odd numbers ( easy fixable with android external device)
And temperatures being in F instead of C ( I am doing the conversion mentally in real time, so .. now is more like a family joke, than inconvenience.
,
However I am a bit frustrated that Toyota USA locked their cars to AT&T , so there is no way to connect it with European GSM Operator.. and toyota application is totally un-useful.
If I can fix this somehow - will be a win!

 

Hi, did you solve a problem.

 

So far no - there is not clear statement from Toyota Europe as well, so I guess it is what it is..
