This preloaded, offshore chartplotter combines the power of networking with brilliant color and slim-line design. The GPSMAP 4208 has preloaded BlueChart® g2 maps of the U.S. coast and displays them on an 8.4" VGA display with 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.

View Detailed Graphics and Video
The 4208 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 4208 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 without having to connect to a computer.

The 4208's high-speed processor draws maps quickly , and its simple intuitive interface makes navigating easy. To keep tabs on your engine room or other area of your boat, you can also connect a live video feed with the 4208's video input and output options.

Add Extras with BlueChart g2 Vision
With the optional BlueChart g2 Vision SD card, you can add a whole new dimension of exceptional features to your chartplotter.

3D mariner's eye view or fish eye view provides you with a 3-dimensional perspective of map information, both above the waterline and below it.
High-resolution satellite images and aerial photographs help you orient yourself in unfamiliar areas.
Auto guidance technology searches through all relevant charts to create a route you can actually follow - one that avoids obstacles, shallow water, buoys and other obstructions.
Connect to the Garmin Marine Network
The 4208 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 4208 and other chartplotters on your boat. You can also add high-powered radar, sonar and XM satellite weather and radio to your system.
