Furuno is one of the most trusted names in marine navigation, known for producing durable, reliable, and feature rich GPS and chartplotter systems for professional mariners, recreational boaters, and commercial vessels. Whether you rely on a Furuno NavNet system, GP series GPS receivers, or integrated multifunction displays, keeping your Furuno GPS navigation updated is essential for safe and efficient operation. Updates ensure that you have the latest chart data, improved performance, enhanced features, and vital security patches. This comprehensive guide explains how to update Furuno GPS navigation, the steps involved, reasons updates are necessary, and common troubleshooting tips.
Why Updating Your Furuno GPS Navigation Matters
Marine environments are constantly changing. New channels open, sandbars shift, markers move, and harbors undergo upgrades. Outdated navigation data can lead to inaccurate routing, misinterpretation of hazards, or unreliable positioning. Furuno releases updates to keep your system aligned with current conditions.
Software updates often improve system stability and performance. They may fix bugs, enhance GPS accuracy, improve satellite communication, refine user interfaces, and add compatibility with new accessories or sensors. Updates also improve integration with other onboard systems such as radars, fish finders, autopilots, and AIS units.
Security is another major reason to keep your Furuno system updated. Modern marine electronics connect with networks, digital displays, and wireless devices, which makes them vulnerable to software flaws. Updating your GPS system ensures protection against potential vulnerabilities.
Preparing to Update Your Furuno GPS Navigation System
Before starting the update, take a few preparatory steps to ensure that everything installs smoothly.
Identify your Furuno model and current software version. Different devices require specific update files, and some systems have their own update procedures. You can locate the software version in the settings or system information menu.
Next, ensure that your boat’s power system is stable. Software updates require uninterrupted power. If your unit is hardwired, confirm your vessel’s batteries are fully charged or keep your engine running for steady voltage. A sudden power loss during a software update can corrupt the system.
You will also need a compatible USB flash drive or SD card, depending on your unit model. Make sure the storage device has been properly formatted and contains enough space for the update file.
Backing up your data is strongly recommended. Furuno systems often store waypoints, routes, custom settings, and radar overlays. Some models allow you to export this information to an SD card for safekeeping. While updates rarely delete user data, having a backup ensures your navigation history is preserved.
Downloading the Furuno Software Update
The next step is obtaining the correct update file for your Furuno model. Through Furuno’s support resources, locate the appropriate software for your GPS or chartplotter. Always verify that the update corresponds exactly to your model number to avoid compatibility conflicts.
Once downloaded, extract the update files if needed. Transfer the files to your SD card or USB flash drive. Ensure that you place the files in the correct directory format recommended for your unit. Some Furuno systems require the update files to be in the root directory, while others may need them placed within a specific folder.
Safely eject the SD card or USB device after the files transfer.
Installing the Update on Your Furuno GPS Navigation System
With the update file prepared, it is time to begin installation. This process varies slightly depending on your Furuno model, but the general steps are similar.
Power on your GPS navigation unit. Insert the SD card or USB drive into the device. Many Furuno units automatically detect update files and display a prompt asking whether you want to install the update. If you do not see a prompt, navigate to the installation or software update section in your device’s system menu.
Select the update option to begin installation. Do not turn off the device, remove the card, or interrupt the power during installation. The update may take several minutes depending on file size and system specifications.
When the process is complete, the unit will typically reboot. After restarting, verify that the new software version appears in the system information menu. If everything looks correct, you can remove the SD card or USB device.
Updating Furuno Chart Data
Furuno offers several chart formats, including vector charts, raster charts, and special fishing charts. Keeping these charts up to date ensures accurate navigation and helps you stay aware of underwater features, contour changes, and newly charted obstacles.
Chart updates can be purchased or managed through chart providers that partner with Furuno. Depending on your chart format, updates may come on SD cards or be downloaded and transferred to a storage device. Some Furuno models support online chart activation or wireless updates when connected to a network.
Insert the new chart card or update storage device into your GPS unit. In most cases, the system will load the new charts automatically. If needed, navigate to chart settings and select the updated chart package. Confirm that your new chart version is displayed correctly.
Updating NavNet Systems
NavNet units, including the NavNet TZtouch series, have specialized update procedures. These systems often support wireless updates through connected networks.
If you have a wireless-capable NavNet system, you may be able to update directly through the internet. Connect your device to a stable Wi Fi network. From the system menu, check for available updates. If a new version is available, you can download and install it without using storage devices.
For older NavNet systems, updates must be installed manually with an SD card. Transfer the update files as described earlier. Insert the card into the unit, access the installation menu, and follow the instructions to complete the update.
Updating Connected Furuno Accessories
Furuno GPS navigation units often work in combination with multiple accessories such as fish finders, radars, sensors, AIS units, autopilots, and sonar modules. These components may also require updates to ensure compatibility and performance.
Most networked accessories update automatically when the main system receives new software. However, some components need manual updates.
Check your system network menu to identify accessories and their current software versions. For modules that support SD card updates, follow the same procedure used for the main GPS system.
Make sure all accessories are powered and connected during the update process. After installation, verify that each device displays the latest version.
Troubleshooting Update Problems
If your Furuno GPS navigation update does not install correctly, there are several steps you can take to troubleshoot.
If the device does not recognize the update file, ensure that the file was transferred correctly and is formatted properly. Confirm that your SD card or USB device is compatible with your Furuno model.
If the update freezes or fails during installation, restart the unit and attempt the process again. Reformatting your SD card and reloading the update files can often solve the problem.
If your GPS unit reboots repeatedly after installing an update, perform a system reset. This does not usually erase user data but can restore proper operation. Consult your device’s manual for reset instructions.
For missing waypoints or routes after the update, reload your backup. If your device refuses to accept the update or displays errors, a factory reset may be necessary. As a last resort, contact Furuno technical support for advanced assistance.
Best Practices for Keeping Your Furuno GPS Navigation Updated
Make updating part of your regular boating routine. Check for updates before long journeys, fishing trips, or seasonal outings. Maintain clean power connections and inspect cables to avoid update interruptions.
Regularly back up your data, especially if you store large waypoint collections. Keep your storage devices clean and dry to avoid read errors. Familiarize yourself with your unit’s menus and settings so that update procedures feel intuitive.
Staying current with updates enhances safety, accuracy, and overall performance, ensuring that your Furuno system remains a dependable companion on every voyage.
