Use the Garmin PowerSwitch digital switch box to control your vehicle’s 12-volt accessories, including light bars, horns, air compressors, differential locks and more. The compact, weather-resistant (IPX7) box is easy to install with no cutting into your dash to mount switches and no interference with vehicle electronics. Wirelessly connect with your compatible Garmin navigator or smartphone downloaded with the Garmin PowerSwitch app and paired with your Garmin PowerSwitch digital switch box for simple control of accessory outputs right from your touchscreen device. Create custom virtual switch panels to activate groups of channels and control dimming and flashing. When the device is paired with a Tread powersport navigator (Sold separately), you can create and use smart switches that automatically activate, based on vehicle speed and time of day.
