Thanks! My friend has said that she has connected her iphone to the car's media system and can make and receive calls through the car's system, however the car does not possess the "carplayer" technology/module and as a result she cannot see her phone apps onto the car's in-built screen, so for example cannot use Ways or Google Maps unless she keeps looking at her phone's screen, which of course defeats the purpose. With "carplay" applications like Ways would appear onto the BMW's screen.
So as I understand it, she needs some upgrade, software or firmware or maybe hardware? She is also trying to return the car.
