Product Specifications

The power of networking meets the brilliance of great design in this large-screen chartplotter, which serves as your all-in-one "nerve center" for the Garmin Marine Network. The GPSMAP 4012 has crisp, video-quality resolution on a whopping 12.1" XGA display as well as a worldwide, satellite-enhanced basemap. By connecting to the Garmin Marine Network, you can add sonar, radar and weather. The 4012 features a worldwide basemap with high-quality satellite images in place of more traditional maps. And for more detail, you can add maps easily with the SD card slot without having to connect to a computer. The 4012'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 4012's video input and output options. The 4012 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 4012 and other chartplotters on your boat. You can also add high-powered radar, sonar and XM satellite weather and radio to your system. This product is bundled with GPS 17 with pole mount adapter.
