In GoogleMaps if you want to change the orientation of the map you change the bearing of the 'camera' being used as perspective of the map.
How do I re-orient a Nokia HERE sdk map? In other words, by default the map is displayed with North at the top. But as the user moves, turns, drives etc., I want to reorient the map to match their course/heading/bearing/direction so that 'forward' is at the top.
I can get the direction the mobile device is facing from the built-in compass sensor without a problem. I just can't find a method or parameter on the map object to set.

The map can be orientated in any direction. By default, the orientation is in a true North position. The following code changes the orientation to South-up:
// Rotate 180 degrees.
map.setOrientation(180);
// Get the orientation, should be 180.
float orientation = map.getOrientation();
