Garmin are using the Google Maps API to display the different g2 and g2 Vision coverage regions in the US. The map shows the range of offshore marine maps that it is possible to buy from the company.
It is possible to define the region coverage size to display on the map. It is also possible to click and drag the map to a different area or zoom in/out of an area, then click "Refresh List" to see a new list of region coverage on the map. The region coverage displayed on the map is also listed in the map sidebar so you can easily click the item you wish to purchase.
