BTW there was disucssion if there is ISA for MK2. didn't find anything mentioned in manual so it could be ISA free. (hooray!)
It'd be great news indeed! And
@Inversed is totally right that according to the EU law the ISA is mandatory only for new models (not facelifts) starting on July '24.
Problem is, Toyota launched a new ADAS system version for its for new cars this year, and one of the first cars adopting it, the facelifted Yaris Cross, has ISA already installed and working (can be switched off, by now), this I know it for sure.
The steering wheel of the new Cross is exactly the same of the GRY Mk2, with the same buttons, including the one I mentioned before that had just a radar symbol on it on the Mk1.
So I guess that the ADAS system mounted on the GRY Mk2 is the last generation one, like in the Cross, so it very likely includes ISA.
But Toyota by now is actually free to decide whether to activate it or not on facelifted models that are not new from scratch, according to the EU law, and then it could be true that there is no (activated) ISA on GRY Mk2, by now.
It's be really great news to me as well!
At least if they don't use the option to activate it later...
