Downloading a Software Update using the Garmin Express App

You should use a blank USB flash drive for updates. The update process erases the content and reformats the USB flash drive.

  1. Turn on the stereo.
  2. Insert the USB flash drive into the USB port on the stereo.
  3. Select Menu symbol > SETTINGS > UPDATE > SAVE GARMIN DEVICES.

    The stereo writes a small file on the USB flash drive that is used by the Garmin Express™ app to identify the stereo and connected devices and download the appropriate update file.

  4. After about ten seconds or more, remove the USB flash drive from the stereo.
  5. If necessary, install the Garmin Express app on your computer (Installing the Garmin Express App on a Computer).
  6. Open the Garmin Express app on your computer.
  7. Insert the USB flash drive into the computer.
  8. If available, select your vessel and device or select the option to add a device by reading the USB flash drive.
  9. If updates are available, select Software Updates > Continue.
  10. Read and agree to the terms.
  11. Select the drive letter for the USB flash drive.
  12. Review the reformat warning, and select OK.
  13. Wait while the software update is copied to the USB flash drive.
    NOTE: Copying the update file onto the USB flash drive may take from a few minutes up to a few hours.
  14. When the process is complete, close the Garmin Express app.
  15. Eject or safely remove the USB flash drive from the computer.

Install the update on the stereo (Updating the Software from a Prepared USB Flash Drive).
