Update. The local manager did ring back and he seems to be a good person. Of course, he didn't have a solution, but he sounded concerned enough to look into the issue.
There is an easy solution. Volvo must commit to retrofit MY21 cars with the MY20 radio. With any luck, the older radio could fit, but Volvo will have a problem sorting out the GUI on the console.
I've been ringing to cancel my order. Still waiting for a call back from the salesman. I much prefer to not cancel, but I don't have a commitment to solve the issue.
Questions must be asked of the Volvo (international) designers of how much consideration they give to places like Australia, Canada, Africa, Sth America, etc. Seems that we are not considered. But, hey, they saved $10!
