google maps app

Question

Does anyone know why I cannot get the zoom level to work with the native Google Maps app?

Here is everything I've tried so far. All I get is a marker that you have to zoom out of several times before you even start seeing tiles.

    //NSString *url = [NSString stringWithFormat: @"http://maps.google.com/maps?spn=%@&q=%@",latlong,latlong];
//NSString *url = [NSString stringWithFormat: @"maps://?q=%@",latlong];
//NSString *url = [NSString stringWithFormat: @"maps://?z=3&ll=%@",latlong];
//NSString *url = [NSString stringWithFormat: @"maps://?f=q&z=3&hl=en&geocode=&q=%@",latlong];
[[UIApplication sharedApplication] openURL: [NSURL URLWithString:url]];

I get the marker on most of the calls above, but I need zoom level of 3, so I can see the continents.
