Thank you very much Joshua!
I was getting crazy, because if you have a look to the reference page (http://docs.coronalabs.com/api/type/Map/index.html) you can see that the property isVisible is not allowed. But you are right, it works perfectly!
One more question: How can I make a route from the actual location to a predefined point? I need to make the route from the user location to one point (I know obviously the latitude and longitude), like the indications provided by GoogleMaps.
