are Interstate, U.S. and state highways, large- and medium-sized lakes 

and streams and more than 60,000 navigation aids with 10,000 wrecks 
and obstructions in U.S. coastal and Great Lakes waters. New for 2007 

are more than 3,000 enhanced lake maps that show better defined 

shorelines, depth contours and other underwater features. 
NOTE: 

The LCX HD models have NauticPath charts, Fishing Hot Spots 
maps and all high detail MapCreate custom maps preloaded on a 

30 gigabyte hard drive. If you own an HD model you do not need to 
load any of those high detail charts/maps into the unit. The unit 

can also use Navionics charts, but they must be loaded via a 

Navionics card. 

MapCreate custom maps include massive amounts of information not 

found in the background map. MapCreate contains: the searchable 

Points of Interest database, all the minor roads and streets, all the 
landmark features (such as summits, schools, radio towers, etc.); more 

rivers, streams, smaller lakes and ponds and their names. 
What's more important is the large-scale map detail that allows your 
GPS unit to show a higher level of position accuracy. For example, the 

background map would show you the general outline and approximate 

shape of a coastline or water body, but the higher detail in MapCreate 
shows the shoreline completely and accurately. Many smaller islands 

would not be included in the background map, but are in MapCreate.
