The easy-to-use GRID 20 remote input device provides intuitive remote access and control of your entire Garmin marine system. It features a 360 deg joystick with a rotary knob and push-to-select button for easy chart plotter menu/setting navigation and fine control, even in the worst conditions. You can designate 4 favorite keys to restore your system to a previously saved configuration. There are also a variety of hard keys for quick access to important functions, including left and right screen switches, autopilot standby/engage and more. For peace of mind, there is also a dedicated SOS key. Wired or wireless installation and vertical or horizontal options allow for a plug and play solution that is tailored to your marine system. Its small footprint makes it convenient to integrate into a busy helm between displays or even into the arm of the captain chair.
