If you are satisfied with this map border and want to finish processing
it for use in your GPS unit, you can jump ahead to "Creating and Sav-
ing a Custom Map," on page 60. However, you might want to check out
the following two optional steps on estimating the size of the map, and
saving the border as a Map Border File.
Estimate Map Size (Optional)
It's a good idea to make sure your map will fit on your card, so let's
check it. Click the
ESTIMATE MAP SIZE button , on the Create
Map toolbar. After a moment it will tell you your map's file size. If it fits
the card, click
OK to clear the message and proceed to either saving the
border file or creating the map. If the map is too big, you must redraw
your map border a little smaller. Click the
DELETE MAP BORDER button ,
click on any green border line or corner handle box, then re-draw a
smaller border box. Use the Estimate button to re-check the size until it is
correct.
