AngularJS jsonp Google Maps

I know there are a lot questions concerning this error but i've tried several ways to solve my problem. I'm just trying to make a jsonp call from angular to google maps with an address as parameter given.

$http.jsonp('http://maps.google.com/maps/api/geocode/json?address=NewYork,TimesSquare&callback=JSON_CALLBACK&key=MY-KEY')
   .success(function(mapData) {
     var data = angular.fromJson(mapData);
     console.log(data);
 });

I'm always getting an syntax error as if the json callback would not work. I've tried it with and without my valid api key. I've also tried to use 'jsonp' as an output parameter in the url. Angular convertes the JSON_CALLBACK to angular_callback._0 but thats it.
