Software Updates

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.

Depending on your stereo and network connections, you may be able to use any or all of these update methods:

  • If you have one or more stereos with Wi‑Fi® functionality or connected to a wireless network, you can update the software using the Fusion Audio remote control app (Updating the Software Using the Fusion Audio App).

  • If you prefer to not use the remote control app, you can update the software using a single-stereo update file loaded onto a USB flash drive (Updating the Software Using a USB Flash Drive).

  • If the stereo is connected to a compatible Garmin® chartplotter, you can update the stereo using a network full marine package update downloaded from the Garmin website or from Garmin Express™ and loaded onto a memory card (Network Update Options ).

You can use this table to best determine what update methods are available for your stereo or stereos and find additional information about each type of update.
