I would still suggest a physical connection rather than software issue: the car always had at least an AUX socket - no software "unaware" of it (mine has it listed even when nothing's connected to it) must be available. It might be just "too clever" to detect a physical "absence" of the socket. Perhaps.
And even if "wrongful" software existed: how could it make it into the car?

This must mean you don't have navigation. I am lazy to check, but you can only download additional data to update it yourself, not the whole car's software which should include the iDrive functionality: I am aware you can't have the software updated with a retrofit (other than original model?) head unit installed. FWIW.
