A question for the technical experts:
I know from experience that my Android phone will show that it is connected to my M3P from, very roughly, 7 or 8 metres away. I also know that I wouldn't be able to unlock the car with the phone until it's physically much closer than that. My question is - given the the car only knows that the phone is connected, how does it detect proximity? Is it simply a question of Bluetooth signal strength?
