When copying files into your maps folder make sure you get all files associated with a particular map. For example, California has 8 files, 1 RMF file for each of the 6 state sections and 2 database files used during an address lookup. One database is used when performing a City Lookup and the other is used when searching by zip/postal codes. For example California_1.rmf California.cdb and California.zdb. Note: when viewing the files in your map folder using the BrailleNote, you may need to change the BrailleNote to display all files including hidden as the BrailleNote hides database files by default. For more information on viewing hidden files, please refer to the BrailleNote's user guide.
