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.

NOTICE

Do not turn off the stereo or disconnect the power during a software update. Turning off the power during a software update may cause the device to become unresponsive.

NOTE: If the stereo you want to update is in a group, you must remove it from the group (Leaving a Group).
NOTE:
  • The stereo may restart a few times while updating the software. This is expected behavior.
  • You can program only newer versions of software on the stereo.
  1. If necessary, connect your mobile device to the stereo using one of these methods:

    • Connect your mobile device to the stereo using a Bluetooth® connection.

      NOTE: You can use a Bluetooth connection to access the stereo information and allow the app to download an update, but you must switch to a Wi‑Fi connection to transfer the update to the stereo at the appropriate time. You cannot update the stereo using only a Bluetooth connection.

    • Connect your mobile device to the stereo using a Wi‑Fi access point on the stereo.

    • Connect your mobile device to a Wi‑Fi access point on the same Fusion PartyBus network as the stereo.

  2. Open the Fusion Audio app, and verify that you can see the stereo in the app.
  3. If your mobile device is connected to a Wi‑Fi access point on the stereo or the Fusion PartyBus network, disconnect the mobile device from the Wi‑Fi access point, and connect it to a different Wi‑Fi network with internet access or to the wireless mobile data connection from your carrier.
    NOTE: You must connect your mobile device to the internet in order to download the necessary software update files.
    TIP: If your Fusion PartyBus network is presently connected to a router with a modem or SIM card that provides internet access, you can leave your mobile device connected to the network instead of disconnecting and using the wireless mobile data connection from your carrier to download the update files.
  4. In the Fusion Audio app, select Settings symbol > GENERAL > Software Update.
  5. Select the Online Software Update.

    The app downloads the software update file.

  6. After the app finishes downloading the update file, reconnect the mobile device to the Wi‑Fi access point on the stereo or the Fusion PartyBus network.
  7. If necessary, in the Fusion Audio app, reconnect to the stereo.
  8. If necessary, select Settings symbol > GENERAL > Software Updates > Online Software Update.

    The app transfers the software update to the stereo over the Wi‑Fi connection, the stereo updates the software, and then it restarts.
