Updating the Software Using the Fusion Audio App

If the stereo has a Wi‑Fi® access point or is connected to a Fusion PartyBus™ network with a Wi‑Fi access point, you can update the stereo software using the Fusion® Audio app, available for compatible Apple® or Android™ on the Apple App Store℠ or the Google Play™ store.

If you have a compatible Apple device, you can use a Lightning™ to USB sync cable (sold separately) connected to the USB port on the stereo and to your Apple device to update the stereo software through the Fusion Audio app.

NOTE: If the stereo you want to update is in a group, you must remove it from the group (Leaving a Group).

  • You can program only newer versions of software on the stereo.
