Garmin GPS III Plus Description GARMIN's 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 up to 1.44MB of data from GARMIN's line of MapSource CD ROM's and you instantly get detailed maps.
Whether you're cruising the streets or pounding the waves, GARMIN has the maps you need. Choose the ''U.S. Roads and Recreation'' CD for city street level detail and even inland marine features such as lake and river shorelines, boat ramp and marina locations. 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.
