Whether you're buying a new boat, or upgrading the electronics on your existing craft, our unique System Builder lets you create a custom, integrated Garmin electronics system for your boat. With the Garmin Marine Network System Builder, you can tailor an electronics installation to fit the needs of the vessel you're outfitting. Simply enter your dash's dimensions and select which electronics you'd like to add. You can explore options in all of our product categories - chartplotters, radar, sonar, autopilots, VHF radios, AIS, weather and instrumentation. Once selected, you can move the applicable equipment around on the "virtual dash" to get a more realistic idea of what your dash will look like. If you're not sure where to start, choose one of our pre-configured systems - a single station powerboat, dual-station sport fish, single-station sailboat or a dual-station powerboat - which suggests the best equipment for your needs. Once you've selected everything you'll need, you can print or email the summary, and can even find the closest dealers in your area - all from the System Builder site. Don't wait...design your dream dash today!
