Excerpt: The Garmin GPSMAP 376C marine and vehicle chartplotter updates the 276C , adding XM satellite radio and weather capabilities. Though listed as a marine unit, this is actually a dual-purpose device that supports City Navigator maps and turn-by-turn routing.
Excerpt: Garmin introduced yet another GPS receiver today, after a rocking week last week where they introduced 6 other devices. This is not exactly a low end, plain old consumer targeted device though, but could signal a direction of things to come for new Garmin models. The great new feature that is available on the GPSMap 376c is the ability to overlay weather on top of your map, and position.
