Garmin GPSMAP 640: For the road and for the sea
Garmin has presented a new GPS system codenamed GPSMAP 640, that will be put on the 2-in-1 category because it can work on the sea, and on the road. The rugged and waterproof GPS has a big 5.2-inch WVGA touchscreen, and as usual, it comes preloaded with maps of North America, plus U.S. coastal BlueChartg2 charts - for the people navigating on the sea.
Thanks to the marine mount, the GPSMAP 640 is able to know when to use the marine mode and the terrestrial mode. While using the marine mode, there is a g2 Vision data card that gives suggestions about the best route to pick, and thanks to photo references, users have an idea of how the ports, marinas, and waterways are suppose to look.
Other details on the GPSMAP 640 - XM WX Sattelite Weather provided by the GXM 40 antenna, which in the end also offers XM Satellite Radio, and XM NavTraffic.
Also with the optional BlueChart g2 Vision technology, the GPSMAP 640 can provide a 3-D "mariner's eye view," for a navigation perspective above the waterline, and a "fish eye view" for an underwater 3D bathymetric contour perspective.
The GPSMAP 640 costs close to $1,200.
