So I might be late to the party but just found something that impressed me.
I do not have Idrive/Navi in my current M3 and when needing directions I use my Iphone 5.
As we all know the new OS has apple's maps on it which is terrible and can only hear the directions off the phone's speakers.
So I went and installed Google Maps onto my phone. Well while using Google Maps, the Bluetooth picks it up and the directions are then voiced out of the car's speakers!
Ah the little things that excites me these days.
