Updating the Software Using a USB Flash Drive

You can update the device 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.

NOTICE

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

NOTE:
  • You cannot update the software using a USB flash drive formatted using the NTFS file system. If you encounter problems updating the device, format the USB flash drive using FAT32 and try the update process again.
  • The device may restart a few times while updating the software. This is expected behavior.
  • You can program only newer versions of software on the device.
  • You can download an entertainment package to update all Fusion Apollo™ stereos connected as part of an entertainment network using Ethernet cables and any Garmin Spectra™ lighting controllers connected to the same NMEA 2000® network as the stereo.
NOTE: If the stereo you want to update is in a group, you must remove it from the group (Leaving a Group).
  1. Select an option to prepare the USB flash drive for updating the stereo software:
  2. After you prepare the USB flash drive with the software-update files, insert the USB flash drive into the stereo and use the stereo interface to proceed with the update (Updating the Software from a Prepared USB Flash Drive).
    NOTE: In some cases, you may have a hideaway stereo that you control using a Garmin® chartplotter connected to the same NMEA 2000 network, not using an Ethernet cable. You can initiate a software update for this stereo or stereo accessories on a USB storage device using the interface on the connected Garmin chartplotter (Updating the Software Using a USB Flash Drive and a Connected Garmin Chartplotter).
