I raised a complaint to the head office in the middle east, which is in the UAE, Dubai.
Just received a callback from them saying “this feature is of course part of the car but unfortunately Google has disabled the wireless Android Auto for this region, and due to connectivity issues, they only enabled wired connection”.
It was a long discussion, basically they can’t help and don’t seem to want to help me achieve this, so they are making excuses.
I don’t know how/why Google would decide to do that if the feature is there on other car manufacturers in this same region.
