Updating the Software as Part of a Garmin Network Update

If the stereo is connected to the same Garmin BlueNet™ network or Garmin® Marine Network as a compatible Garmin chartplotter, you can perform a network update on the chartplotter to update all of the connected Garmin devices and Fusion Apollo™ stereos.

NOTE: If you have one or more NRX remote controls connected to the stereo, they are not updated as part a marine network update. You must perform updates to those devices individually (Update Options ).
  1. If needed, go to garmin.com/manuals and locate the latest version of the owner's manual for your connected chartplotter.
  2. Select an option:

    • Use the ActiveCaptain® app to initiate the software update.

    • Go to garmin.com/support/software/marine/ to download the latest marine update .

      NOTE: If you do not use the ActiveCaptain app, you must download the update and install it using a memory card on the chartplotter.
  3. Follow the directions in the chartplotter owner's manual for performing a network update.

    The software is updated on all of your connected devices, including the stereo.

NOTE: Depending on the capabilities and software version of your connected chartplotter, it may not include this stereo in the Garmin network update until after the chartplotter is updated to a more-current version. If the stereo is not updated after the network update completes, try performing the network update again. If the stereo is not updated after the chartplotter is up-to-date, perform a manual update on the stereo instead, using the Fusion® Audio app or a USB drive (Software Updates).
