Using StructureMaps with mapping cards

StructureMap allows you to maintain full chart capability and can be used 

with embedded cartography as well as  Navionics, Insight and other third-

party charting cards compatible with HDS units. To view StructureMap data 

with other mapping card data on an HDS-8 or  HDS-10, place the mapping 

card in one card slot and the SD card with the StructureMap file in the other 

slot.

If you have an HDS-5 or HDS-7, copy the StructureMap (.smf ) files to the 

units internal memory to view StructureMap data with data from another 

mapping card. We recommend only adding StructureMap (.smf) files of one 

lake at a time to the internal memory due to limited space. You should keep 

copies of StructureMap (.smf ) files on an external SD card. 

Show StructureMap (.smf) files

You can view StructureMap (.smf) files from the Files menu, which allows you 

to quickly see what area each StructureMap file covers. 

Viewing StructureMap (.smf) files
