Add a Location Service component, enable Create Marker and enable Use Compass.

I'm new to all of this and I'm wondering how can I get the user's GPS location and rotation (the direction the user is heading) and draw it on the map? Just like in google map, there will be a blue dot showing your location and the direction you are facing. I want to draw an icon on the map and update it with the user's location and direction. Can you show me how I can do this? Thank you in advance!
