Software Updates

NOTICE

Failure to regularly update the software on your radio and connected devices may result in poor product performance.

Garmin® releases software updates for marine devices on a regular basis. These software updates provide support for new products, software improvements, or product performance enhancements. You should update the software regularly throughout the life of the product for the best performance.

If your Garmin Signal™ VHF radio is connected to the ActiveCaptain® app on your mobile device, the app automatically prompts you to install new software updates when they become available.

For more information on connecting the Garmin Signal VHF radio to the ActiveCaptain app, see the Quick Start Manual in the product box.

If your Garmin Signal VHF radio is connected to a Garmin BlueNet™ network with a compatible Garmin chartplotter, the software on the Garmin Signal VHF radio updates automatically when you update the software on the chartplotter.

You can find information on the latest Garmin marine device software updates at garmin.com/support/software/marine/.

For complete information on updating the software on the Garmin Signal VHF radio, see the Owner's Manual at garmin.com/manuals/SignalVHF.
