How to show phone orientation on google maps?

Question

I have a GoogleMap object. Map is visible, all OK. On the map we can see a standart blue marker - current position of user. Sometimes this marker shows us an arrow - phone orientation (were we are looking now). Question: what me must do to ALWAYS show this arrow?

Or maybe you can tell me, how to enable "navigator mode" with screen rotation (example 2)?

Answer 1

I found the answer: Arrow not shows, when you use wi-fi! If you go on the street with GCM or GPS, arrow will be visible!:)
