So all they are doing when you buy the Polestar option is sending a request to Volvo/Polestar to say add a tick next to this option against this car's VIN.

Then when they reload the software for your car, because the option is ticked it now writes the Polestar software instead of the normal software.

But because its just an option against your VIN, next time the software of your car is updated in general, I'm guessing if there are Polestar updates to the maps, etc, they get upgraded too.

This is all just guesswork based on what I've seen! Could be wrong!
