Well, i extended my testing with other car brands. Here are some that are working. I tested many features, that includes calling.
BMW (Mini also…), Mercedes, Fiat, Toyota.
With all of the brands above (tested in multiple models) it should work no problem. Below there are brands that have some issue with AA with Nothing 2a.
VW Group (incl. Porsche), Suzuki (only tested on Vitara), Peugeot.
Will try one thing that many people suggesting and that is clearing the data of the AA. And we will see if that helps.
