I can detect the wi-fi from the supra, but I cannot use the screen mirror from my phone. In the media menu I do not have the mirroring option near the usb option.
I wonder if it is linked to the fact the navigation hasn't been activated either.
Update. I spoke to my dealer in Germany to tell him that they need to navigate the navigation and showed him the variables that need to be turned on for screen mirroring.
He checked internally and emailed me the next day to say that they didn't know about the need to activate these things but confirmed with Toyota that they should.
Now waiting for them to receive the navigation code and they will activate both features - Navi and mirroring.
