MapSource BlueChart CD Rom's by Garmin are available for 3 different Zones: Americas, Atlantic, and Pacific (Australia, Asia). With the purchase of a BlueChart CD Rom, you will acess to ONE region of coverage within that Zone. Each Blue Chart Region Unlock Certificate allows you to gain access to ONE additional coverage area. The CD has the same features as the pre-programmed charts as well as real-time track plotting on PC. The large coverage area mirrors that of the pre-programmed charts.

Complementing Garmin's new line of handheld mapping units and marine chartplotters, BlueChart cartography is designed to provide interactive viewing of detailed nautical chart data. BlueChart provides navigators with innovative object oriented cartography. Descriptive details for features typically found on nautical charts can easily be viewed with a simple key press. Cursor movements over the chart provide descriptions for contour depth, chart number, navaid name, and much, much more. When displayed on a Garmin chartplotter, BlueChart offers you a paper chart-like appearance. This data will include shaded depth contours, inter-tidal zones, spot soundings, wrecks, navaids, port plans, restricted areas, cable areas, anchorages and more. Additionally, BlueChart includes chart numbers, name, scales, revision dates and Notice to Mariner dates. BlueChart offers detailed paper chart-like, vector cartography in large coverage areas so choosing your desired region is easy.
