title: iPhone SDK Mapkit: How can I check if the user's location is in the same street/avenue as a given coordinate?
body: <p>My iPhone App is an Application that shows users some POI (points of interest) in the MapView.
  I wanto to give the user the option to turn on a feature that would only highlight the POI's that are in the same street, avenue, route, etc as his.</p>
  
  <p>Is there a way to aproach this?</p>
  
  <p>Thanks a lot!</p>
