I just ordered a 2017 X5M. One of the options is Apple Carplay. The salesman does not know much about this because it is a new option. Does anyone know how this works? I have read alot about Apple Carplay in other cars and seen some videos. I want to make sure that the typical BMW navigation, phone book, etc will still be available and not replaced by the iphone apps. Supposedly the carplay apps are only available when the phone is plugged in but I read another article that stated that BMW's carplay will be wireless. If the phone is connected to the car through bluetooth, will the phone apps replace the BMW functionality? Thanks for your help.
