Lowrance mapcreate 7 User Manual

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 dif-
ferent 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 
purchased 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 examples 
using the regular versions (no topographic data) of MapCreate USA and 
MapCreate Canada, with all mapping categories included. (Size will vary 
depending on which package of MapCreate you have.) 
In the U.S., Lake Michigan is approximately 26 MB, all of Missouri is 41 
MB and the entire state of California is approximately 87 MB. A six-mile-
wide corridor map from San Diego, California to the Maine-Canada bor-
der, following Interstate highways, is about 50 MB. 
In Canada, a map of Lake Winnipeg (including the major lakes to the 
northwest) is 6.84 MB. All of Saskatchewan is 64 MB; all of British Co-
lumbia is 69 MB. A six-mile-wide corridor map from Prince Rupert on 
the west coast to Louisbourg on the east coast, following Trans-Canada 
highways, is about 35 MB. 
Important Notes about Cards and File Size 
The size of a Map File is important. It must be small enough to fit on 
the MMC (MultiMedia Card) that your GPS uses for data storage. This 
solid-state, flash memory device is about the size of a postage stamp. 
(SD [Secure Digital] cards are also compatible with any Lowrance or Ea-
gle product that uses MMCs.) 
At press time, the MMCs shipped with the GPS Accessories Pack ver-
sion of MapCreate 7 are 32 MB size. If you're using a 32 MB MMC, 
your Map File must be less than 32 MB in order to fit on the card. (This 
space issue is the same as floppy disks; you can't really fit a 1.44 MB 
file onto a 1.44 MB diskette because some space is required for the 
disk's file allocation table. In the case of a 32 MB MMC, actual maxi-
mum useable space will be approximately 29 MB to 30 MB.)
