Background map vs. MapCreate map content 
The special built-in Lowrance background map contains basic world-

wide coverage of major inland lakes, rivers, streams and coastal wa-

ters, plus key cities, highways, and more. 
MapCreate custom maps include massive amounts of information not 

found in the background map. MapCreate maps contain 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 is 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 

included in MapCreate.
