The version of the API that is used on maps.google.com differs from the one used in the Pro Maps for Google. It is often best to get coordinate values for these locations and use the coordinates instead.
A good way to get the coordinate values for these locations is to go to the location on maps.google.com and put the following code in your url then go to it:
javascript:void(prompt('lat,%20lng',%20gApplication.getMap().getCenter()));
It will return the exact lat and long for what is centered on the map.
