It looks as if you want to display a mapView in a modal view.

On iPhone, modal views occupy the entire screen, so there is no room for a nav bar. Thus you do not need a navigation controller.

I assume the above code is inside a UIViewController instance. If so, just do this:

  [self presentModalViewController:mapView animated:YES/NO];

In this case, in your your mapView controller, you should add a button that, when pressed does this:

  [self dismissModalViewControllerAnimated:YES/NO];
