GPS III + £357.91
Garmin's new GPS III Plus offers cartographic capabilities formerly
found only in high-end automotive navigation and marine chartplotting
units. Simply plug it into a PC and download an extra 1.44 MB
of map data from Garmin's line of MapSource™ CD ROM's to
give you instant detailed maps.
Whether you're cruising the streets or pounding the waves, Garmin
has the maps you need. Other CD's give you worldwide coverage
of coastlines, including a database of coastal cities, navaids
and inland roads.
Even without additional cartography, the basemap in the GPS III
Plus will get you where you're going. More than 10,000 new towns
have been added to the permanent basemap, as well as airport locations,
secondary roads in metro areas and even detailed exit information
for the federal interstate highway system, including information
about available lodging, food and service stations.
