This mid-sized 4000 series chartplotter fills the gap between the smaller GPSMAP 4208 and the wider GPSMAP 4212. Like its counterparts, the 4210 combines the power of networking with brilliant color and slim-line design. This chartplotter has preloaded BlueChart g2 maps of the U.S. coast and displays them on a 10.4" SVGA display with crisp, video-quality resolution. By connecting to the Garmin Marine Network, you can add sonar, radar and weather. For even more enhanced features, you can add the optional BlueChart g2 Vision card. The 4210 features highly detailed BlueChart g2 marine cartography of the coastal United States, including Alaska, Hawaii and the Bahamas. This data provides detailed coastlines, shaded depth contours, navaids, port plans, wrecks, restricted areas and tide and current information. For other areas, the 4210 has a worldwide basemap with high-quality satellite images in place of more traditional maps. With the SD card slot, you can add additional maps. The 4210 connects easily to the high-speed Garmin Marine Network, so you can interface with additional MFDs and add remote sensors. Once connected, you can share information between the 4210 and other chartplotters on your boat. You can also add high-powered radar, sonar and XM satellite weather and radio to your system. Includes external GPS antenna, power/data cable, video cable, bail and flush mount.
