To find the address location on Google Maps:
If the selected contact has more than one address, select an address from the drop-down list. It will open your default web browser on the Google Maps page. If the address is sufficient and accurate, Google will find the location on the map.
If the address is insufficient, these options and address link will be disabled. For an address to be sufficient, it has to have at very least : City, State/Province/County, and ZIP/Postal Code, and in some cases, the Country.
