GARMIN mapping units come with built-in, permanent basemaps
that cannot be altered. These basemaps come in a variety of global
designations (e.g. Americas basemap, Atlantic basemap, Pacific basemap).
Please check when purchasing a Garmin mapping unit to ensure
that you purchase one with a basemap that's appropriate for your
location and needs.

are supplied by GARMIN only to dealers in the Americas; Atlantic
basemap models can only be purchased from dealers within the detailed
coverage of that basemap, and likewise for Pacific basemap models.
