on the iPhone 3GS in the "Maps" app you can click the icon which usually shows your position twice and the blue dot gains what looks like a beam from a headlamp, basically showing you the direction you are facing on the map and rotating the image accordingly. 

Is this option available using MapKit MapView ?

I'm know that I can get my heading with something like

```
- (void)locationManager:(CLLocationManager *) manager didUpdateHeading:(CLHeading *) newHeading {

```

// If the accuracy is valid, process the event.

```
if (newHeading.headingAccuracy > 0) {

    CLLocationDirection theHeading = newHeading.magneticHeading;
    ...
}

```

}

but I don't know how to get that nice headlamp effect in Mapkit and there doesn't seem to be any documentation. 

Any ideas?
