you can switch between 2d and 3d by pressing the icon right below the compass
Yes, but in 2D maps I cannot select between Heading or North. If I am wrong, great because I really like 2D maps better and don't want the map to always show North view and not have the map rotate based on the direction I am heading when I am in 2D map view. I know that 3D orients to your heading, but that doesn't help in 2D map view.
