MapKit and touch events problem

So I'm using mapkit at the moment to display some google maps

I want to allow user interaction (touchesBegan method etc)
Problem is once i add the the mapView as a subview it doesn't recognize any touch events

i have:

Code:

mapView=[[MKMapView alloc] initWithFrame:self.view.frame];
	//mapView.showsUserLocation=TRUE;
	[mapView setUserInteractionEnabled:YES];
	mapView.mapType=MKMapTypeHybrid;
	mapView.delegate=self;
	[self.view insertSubview:mapView atIndex:0];

;

I just tried setUserInteractionEnabled:YES
But that doesn't make any difference
I'm guessing I'm missing something pretty important to add touch events to the sub view?

any help would be useful! thank you

PS: i want to do this with the map still allowing its old touches (pinch to zoom and drag to move map) i just wan to tap the screen once and record that information
