For best results, you should update the software in all Fusion^® devices regularly. Some features, such as the Fusion PartyBus™ group functionality may not work properly unless all connected stereos are using the same software version.

You can update the software using the Fusion Audio remote control app on your compatible Apple^® or Android™ device.

You can update the software using a USB flash drive. You can prepare a suitable USB flash drive by manually downloading and loading the update files, or you can use the Garmin Express™ app.

If the stereo is connected to the same network as a compatible Garmin^® chartplotter, you can update the stereo as part of a full network device update through the chartplotter (Network Update Options ).
