Many companies provide charts for GPS systems but few serve the needs of aviation, offshore marine and inland boaters as well as all branches of the U.S. military. In fact, the National Marine Electronics Association awarded C-Map the NMEA award for Best Electronic Cartography for 2003. C-Map has had five other NMEA awards in previous years. Our chart came complete with all inland waterway markers as well as underwater obstructions that could have damaged our boat. Ramps and marinas were also clearly marked on the charts.

Installation and Operation Tips
-We like the GPS with internal antennae for most boats with open helms since there is no real need for a separate antenna. It shortens the installation process, lessens the cost and makes removing the unit from its pedestal easier for security.
-We prefer mounting the unit on its pedestal on top of the helm so the captain can adjust settings while scanning forward for oncoming traffic.
-A flush-mounted unit looks great but becomes a permanent part of the boat -- unless a thief wants it for his own.
-The screen was bright and easily readable even in the direct sunshine.
-At sunset, you may want to dim the backlight to save your night vision.
-Navman GPS units use handy C-Map cartography, and no matter where you boat, how small or how large your lake, there is a C-Map Cartridge to make your boating more enjoyable.
