Stage 1: Populating the mSD Flash Memory Card with the MFD Software

Note: To avoid potentially corrupting the data on your Navionics chart card, DO NOT copy software update files to your Navionics chart card and DO NOT back up waypoint/route/track data to your Navionics chart card. MicroSD cards are commonly available in most stores selling consumer electronics products. Waypoint, route, track data, and system configuration data can be stored on a microSD memory card which also contains software update files.

  • You are NOT required to update the products software versions sequentially. For example, you can go from v6.27 to v14.36
  • The mSD (Micro SD) memory cards used with a/c/e/eS/gS Series MFDs should have a memory capacity of no less than 1GB and no more than 32GB.
  • The mSD card should be formatted to FAT32. (External link: Instructions)
  1. Insert a compatible Flash memory card into the computer's memory card reader or into a memory card reader which has been interfaced to the computer.
  2. Select the appropriate software download for your product from HERE
  3. Upon completion of the download, click on the folder where the downloaded files have been saved to open it
  4. If the downloaded file is a .ZIP file, extract the contents of the .zip file
  5. Copy all new downloaded files to the Root of the Flash card (Root is the first level you access when selecting the Flash).
    1. If the Download is an ISO file, do not try to open the file, instead just copy the whole ISO file over to the mSD card.
  6.  Make sure the files are not in any folders on the card
    (See video below for examples. Files will vary depending on update)

    • For example: if your computer has assigned Removable Disk (E:) to your memory card reader/writer, then the software update files should be copied directly to Removable Disk (E:), not to any folders created on the memory card.

    • Note: You are only opening the ZIP file that is downloaded. You cannot open the files contained in the ZIP file, these have extensions such as .dob .pkg .sh .sh.sig .iso with various file names. If you attempt to open these files you will see an error as they are designed to update your Raymarine products and not for use in a Windows, Apple or Linux PC.

  7. Remove the memory card from the computer's memory card reader.

Updating a RMK-9 using a, c, e, eS or gS Series MFD's

  1. Please make sure RayNet is connected to both the RMK-9 and the MFD and all are powered before starting the update procedure.
  2. Place the mSD card with the RMK-9 ISO file into the MFD. After a few seconds the MFD should display a pop-up stating the ISO software file has been discovered.
    •     To make this occur faster, from the home screen you can enter Set-Up>Maintenance>check card for updates.
  3. The MFD will search for all connected products on the network and will list the devices that require an update
  4. Follow the on screen instructions to proceed to upgrade the software in the RMK-9.
  5. MFD will show update % progress as it's being updated.
  6. MFD will show “Update Complete” when unit has been updated.
  7. Once all the devices in the system are updated, remove the mSD Card and Power Cycle the whole System.
  8. Please verify that this is correct by going to the "checking the software versions..." section below:
