MapKit user location (Blue Dot & Circle) will not be displayed

Question

I can’t understand why the current location circle will not appear. I have custom annotations that look just fine ... and the map is taken to the user's current location ... but the circle does not appear.

Here is my code. Thanks in advance!

- (void)viewDidLoad {
    [super viewDidLoad];

 locationManager = [[CLLocationManager alloc] init];
 [locationManager setDelegate:self];
 [locationManager setDesiredAccuracy:kCLLocationAccuracyBest];
 [locationManager startUpdatingLocation];

 [mapView setMapType:MKMapTypeStandard];
 mapView.showsUserLocation = YES;

 MKCoordinateRegion region = { {0.0, 0.0 }, { 0.0, 0.0 } };
 region.span.longitudeDelta = 0.005;
 region.span.latitudeDelta = 0.005;
 [mapView setRegion:region animated:YES]; 
 [mapView setDelegate:self];
}

- (void)locationManager:(CLLocationManager *)manager didUpdateToLocation:(CLLocation *)newLocation fromLocation:(CLLocation *)oldLocation  {
    CLLocationCoordinate2D loc = [newLocation coordinate];
    [mapView setCenterCoordinate:loc];      
    }

-(MKAnnotationView *)mapView:(MKMapView *)map viewForAnnotation:(id <MKAnnotation>)annotation {
    static NSString *AnnotationViewID = @"annotationViewID";
    MKAnnotationView *annotationView = (MKAnnotationView *)[mapView dequeueReusableAnnotationViewWithIdentifier:AnnotationViewID];

    if (annotationView == nil) {
        annotationView = [[[MKAnnotationView alloc] initWithAnnotation:annotation reuseIdentifier:AnnotationViewID] autorelease];
        }

    annotationView.canShowCallout = YES;

    if ([annotationView.annotation.title isEqualToString:@"One"]) {
        UIImage *pinImage = [UIImage imageNamed:@"one.png"];
        [annotationView setImage:pinImage];
    }

    if ([annotationView.annotation.title isEqualToString:@"Two"]) {
        UIImage *pinImage = [UIImage imageNamed:@"two.png"];
        [annotationView setImage:pinImage];
    }

    annotationView.annotation = annotation;
        return annotationView;

    }

Add this to the top of the viewForNnotation method:

if ([annotation isKindOfClass:[MKUserLocation class]])
    return nil;  //return nil to use default blue dot view
