Garmin GPSMAP 4008 Multi Function Display



The power of networking meets the brilliance of great design in this chartplotter, which serves as your all-in-one "nerve centre" for the Garmin Marine Network. The GPSMAP 4008 has video-quality resolution on an 8" (21 cm) VGA display as well as a worldwide, satellite-enhanced basemap. By connecting to the Garmin Marine Network, you can add sonar and radar. For even more enhanced features, you can add the optional BlueChart® g2 Vision® card.

View High-res Video and Graphics

The 4008 features a worldwide basemap with high-quality satellite images in place of more traditional maps. For more detail, you can add maps easily with the SD™ card slot without having to connect to a computer. The 4008'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 also can connect a live video feed with the 4008's video input/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.

  • MarinerEye view and FishEye view provide you a 3-D perspective of map information, both above and below the waterline.
  • 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 4008 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 4008 and other chartplotters on your boat. You also can add high-powered radar and sonar to your system.
