8.6 How to Update the System Software
You can download the current software and chart for the NavNet 3D from www.nav-
net.com, if you use the "request update file" feature. This feature saves the information
(program and chart version numbers) about your system to a SD card. You load the
file saved to the SD card on your PC and open the NavNet homepage. Follow the in-
structions on the homepage to check your software and chart version numbers. If the
version on the homepage is newer, download and install the software updates. Use a
SD card of at least 2GB to do this procedure.
You can check your NavNet 3D version from the [My NavNet-General] menu.
Step 1: Export current status data from NavNet 3D to SD card
1. Put a blank SD card in a card slot of the Master MFD.
2. Open the [Files-General] menu and select [Request Update File]. The SD card
confirmation screen appears after you push the RotoKey.
3. Select Yes then push the RotoKey. The card is formatted, the file FURUNO Sys-
tem Diagram.sys is created and saved to the SD card. This may take several min-
utes.
After the message “The SD card has been initialized...” appears, remove the SD
card and use the RotoKey to select the OK button.
Step 2: Access www,navnet.com to download latest software

3. Click Browse to proceed.
4. Select the file FURUNO System Diagram.sys from the Uploader folder in the SD
card.

7. Download and save the software "YYYYMMDD_NN3D.zip" onto your desktop.
8. Unzip "YYYYMMDD_NN3D.zip", and you will find "UPLOADER"(folder) and "re-
adme.txt". If you see the message “Folder already exists. Overwrite”, select Yes.
