Updating the firmware on your Lowrance GPS is one of the most important steps you can take to keep your marine electronics running smoothly. A Lowrance GPS firmware update enhances system reliability, improves navigation accuracy, and ensures compatibility with the latest charts and accessories. Whether you use your device for fishing, cruising, or offshore navigation, keeping the firmware current helps you get the best performance every time you head out on the water.
This article explains what a Lowrance GPS firmware update is, why it matters, and how to complete the update correctly.
What Is a Lowrance GPS Firmware Update?
Firmware is the core software that controls how your Lowrance GPS operates at the hardware level. It manages essential functions such as GPS signal processing, system startup, chart rendering, sonar operation, and communication with connected accessories.
Unlike map or chart updates, a firmware update directly improves how the device itself functions. Firmware updates typically include bug fixes, performance enhancements, stability improvements, and support for new features or hardware.
Why Lowrance GPS Firmware Updates Are Important
Running outdated firmware can cause slow performance, inaccurate GPS positioning, unexpected shutdowns, or compatibility issues with newer charts and accessories. Lowrance regularly releases firmware updates to fix known issues and enhance device reliability.
Key benefits of updating Lowrance GPS firmware include:
- More accurate and stable GPS positioning
- Faster startup and smoother operation
- Reduced system errors and crashes
- Improved sonar and chart performance
- Compatibility with new accessories and updates
Keeping firmware up to date ensures your device performs as intended in real-world marine conditions.
Lowrance GPS Models That Support Firmware Updates
Most modern Lowrance GPS and fishfinder units support firmware updates, including:
- Lowrance HDS series
- Elite FS and Elite Ti models
- Hook Reveal and Hook series
- Other compatible Lowrance chartplotter and combo units
Always verify your exact model before downloading firmware, as each device requires a specific update file.
What You Need Before Updating Firmware
Before starting a Lowrance GPS firmware update, make sure you have:
- Your Lowrance GPS unit
- A computer with a stable internet connection
- A blank microSD card (8–32 GB recommended)
- A microSD card reader
- A reliable power source for the GPS unit
It is strongly recommended to back up your waypoints, routes, and tracks before updating, even though firmware updates rarely erase data.
How to Check Your Current Firmware Version
Turn on your Lowrance GPS and open the Settings menu. Navigate to System or About to view the currently installed firmware version. Compare this version with the latest firmware listed on the official Lowrance support website for your specific model.
If a newer version is available, performing an update is advised.
How to Update Lowrance GPS Firmware
Step 1: Download the Firmware File
Visit the official Lowrance website and go to the support or downloads section. Select your exact GPS model and download the latest firmware update file to your computer.
Step 2: Prepare the microSD Card
Insert the microSD card into your computer and format it if necessary. Copy the downloaded firmware file directly to the root directory of the card. Do not rename the file or place it inside a folder.
Step 3: Install the Firmware Update
Power off your Lowrance GPS unit. Insert the microSD card into the device, then power it on. The system should automatically detect the firmware update and prompt you to begin installation.
Step 4: Complete the Update Process
Follow the on-screen instructions carefully. Do not remove the microSD card or disconnect power during the update. The process may take several minutes, and the unit may restart one or more times.
Step 5: Verify the Update
Once the update is complete, return to the System Information or About menu to confirm the new firmware version is installed.
Best Practices for Firmware Updates
- Perform firmware updates at home, not on the water
- Ensure a stable power supply throughout the update
- Remove any additional microSD cards before updating
- Update firmware before installing new charts or maps
- Review release notes for details on fixes and improvements
Following these best practices reduces the risk of update errors.
Common Firmware Update Issues and Troubleshooting
- Update Not Detected: Ensure the firmware file matches your exact model and is placed in the root directory of the microSD card.
- Update Appears Frozen: Wait several minutes before restarting, as some updates take longer to complete.
- GPS Issues After Update: Allow time for satellite reacquisition or restart the device.
- Missing Waypoints: Restore your data from a backup if needed.
If issues persist, Lowrance customer support can provide model-specific assistance.
