Important Information
MAP DATA INFORMATION: One of the goals of Garmin is to provide customers with the most complete and accurate 
cartography that is available to us at a reasonable cost. We use a combination of governmental and private data sources, which we 
identify in product literature and copyright messages displayed to the consumer. Virtually all data sources contain some inaccurate 
or incomplete data. In some countries, complete and accurate map information is either not available or is prohibitively expensive.
