Using Garmin's Mapsource CD ROMS, (either the land-based for about 100 bucks,
or the marine cd, 70 bucks), you can upload up to 25 specific maps into the
unit, of either type or both. The land-based CD is the entire US, and the
marine CD is all US inland and coastal waters. With the same information of
Navionics C-MAP and G-Chart cartridges, and then some. Not too bad, $369 for
the GPS, $170 in two CD's, and you have a GPS with detailed cartographic data
for the entire United States... C-MAP cartridges can get expensive.. up to
$400 a whack.
We just got them in here, and I have had the chance to play with it.....
Pretty slick!
