You cannot make changes to a Map File once it has been created. If you
want to make changes to a map, return to its original companion Map Bor-
der File or retrieve the map borders by opening the Map File (*.lcm). Make
your changes to the border, then create a fresh Map File. You can delete
the old one, or just save the new map over the old map.
Important Notes: File Encryption and Card Limits
We collect and purchase cartography data from several sources. Much of
this data is copyrighted, and our data suppliers require that we protect our
maps from illegal copying. One level of protection requires that you have a
MapCreate CD in the disc drive each time you launch the program. We
also encrypt Map Files, and limit the number of MMC or SD cards you can
use to store maps.
Map File Encryption
All maps built by MapCreate are required to be encrypted (or locked) to a
specific memory card. This encryption process must be done on maps
saved both to a memory card and your hard drive. Once a map has been
encrypted to a specific memory card, you can make a backup copy on your
hard drive, but you cannot copy the map to a different card. (Well, you can
copy it to another card, but your GPS unit won't recognize it. To work, the
Map File must reside on the card it was encrypted to.)
Limited Number of Cards
All MapCreate users are limited to saving maps on a maximum of five dif-
ferent memory cards. MapCreate tracks the number and identity of your
cards by "registering" each card with the program. The software needed to
register cards will not work with third-party card readers, so MapCreate will
only work with the card reader from LEI. Once you have registered a card,
it can never be unregistered and its place exchanged with another card.
Since you are limited to five, we strongly recommend that before you buy
more cards, you should give some thought to the type of travel you do and
your map size requirements. Memory cards come in several different
sizes, so you need to think ahead and match card capacity to the type of
maps you will need.
To help you decide what size cards to buy, make some map borders cov-
ering the type of travel you expect. Then use the Estimate Custom Map
Size command to calculate the size.
For example, one Missouri customer frequently travels and fishes in the
four-state area of Kansas, Missouri, Arkansas and Oklahoma. He pur-
chased an additional 128MB MMC, which holds all four states at once.
This lets him travel long distances for extended periods without needing a
computer to change the maps on his card.
To give you an idea of how big a Map File can be, we made some exam-
