and some major city streets. Also included 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. 
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 (finer detail). Many 

smaller islands would not be included in the background map, but are 

in MapCreate. 
NOTE: 

Available through LEI Extras (look inside back cover for accessory 

ordering information), FreedomMaps are pre-made maps that con-

tain all of the same information available in a custom MapCreate 

map, without any work on your part.
