I've realised something kind of amusing: the position we are tracking with PositionModel is NOT the position of the phone, it is the position of the centre of the view! But the events are only sent when the GPS updates, not when the view is updated. I don't know if this is a bug or what. In any case directions will only work when you have the view tracking the position.
