Product Overview

Get the integrated boat experience with Garmin Boat Switch. This all-in-one digital switching solution lets you operate up to 20 circuits right from your compatible GPSMAP® or ECHOMAP™ chartplotter instead of using physical buttons or switches.

It offers four different switch types, including on/off for bilge pumps and nav lights, press-and-hold dimmers for cabin lights, momentary outputs for horns and timers to circulate your livewell pumps. Plus, it provides built-in tank sender detection and calibration for as many as four tanks — including fuel, water and graywater. It installs without special tools and allows you to easily add and name switches on your chartplotter display.


  • All-in-one system replaces existing fuse box and switches on boats for easier control and operation of onboard functions
  • Offers control and protection of up to 20 circuits from your compatible GPSMAP® or ECHOMAP™ chartplotter rather than a physical button or switch
  • Manage four different output types, including on/off toggle, dimming, momentary on and built-in timer for livewell pumps
  • Position, name and remove switches on the easy-to-use chartplotter interface
  • Easily retrofit into existing boats without special tools, training or configuration by using included 18” flying leads and color-coded channel wires
