What is a Firmware Update and Why is It Important?

Firmware is a type of software embedded in the hardware of your device. It controls the basic functions of the GPS unit, such as processing data, handling navigation tasks, and managing the user interface. Firmware updates are issued by manufacturers like Lowrance to address issues, enhance features, and ensure compatibility with new maps or charts.

Regular updates can significantly improve the performance of your device.

Updating your Lowrance GPS unit is an essential part of maintaining its longevity and performance.

Steps to Perform a Lowrance GPS Map Firmware Update

Performing a Lowrance GPS map firmware update is a relatively simple process. Here are the steps you need to follow to make sure your device is up to date.

1. Check for Available Updates

Before starting the firmware update process, it’s important to check whether there is a new firmware version available for your device. Lowrance provides firmware updates on its official website, and you can check if your GPS unit is eligible for an update by following these steps:

Visit the Lowrance Website: Go to the official Lowrance website (www.lowrance.com) to check for the latest firmware updates.
Identify Your Device Model: Make sure you know your GPS unit’s model number, which can typically be found on the back of the device or in the user manual.
Check for Updates: Navigate to the "Support" or "Downloads" section of the website and look for firmware updates for your specific GPS model. Lowrance regularly posts new updates, so it’s a good idea to check periodically.

2. Download the Latest Firmware

Once you’ve confirmed that a firmware update is available for your GPS unit, you need to download the firmware file to your computer. Here's how:

Connect to a Computer: Use a computer that has internet access to download the firmware. You will also need a microSD card or USB drive to transfer the update to your GPS unit.
Download the Firmware File: Locate the firmware file for your device model on the Lowrance website. Ensure that the version of the firmware matches your GPS device’s model.
Save the File: Once downloaded, save the firmware update file to your computer.

3. Prepare Your MicroSD Card or USB Drive

Next, you need to prepare a storage device (either a microSD card or USB drive) for the update. Lowrance GPS units use these external storage devices to transfer the firmware update.

Insert the Card/USB Drive: Insert your microSD card or USB drive into the computer’s card reader or USB port.
Format the Storage Device (if necessary): Before transferring the firmware update, it’s recommended to format the microSD card or USB drive to ensure no old files will interfere with the update process. Use FAT32 formatting, which is compatible with most Lowrance devices.
Transfer the Firmware File: Once the storage device is formatted, copy the firmware update file from your computer onto the root directory of the microSD card or USB drive.

4. Insert the Storage Device into Your Lowrance GPS Unit

With the firmware update file now on your storage device, it’s time to transfer the update to your Lowrance GPS unit.

Turn Off the Device: Ensure that your GPS unit is powered off before inserting the storage device.
Insert the Card/USB Drive into the GPS Unit: Insert the microSD card or USB drive with the firmware update file into the appropriate slot on your Lowrance GPS device. The slot is typically located on the side or bottom of the unit.
Power On the Device: After inserting the storage device, power on your GPS unit. Your Lowrance GPS unit should automatically detect the firmware update file on the storage device.

5. Install the Firmware Update

Once the device detects the firmware update, it will prompt you to begin the installation process. Follow these steps to install the update:

Confirm the Update: The GPS unit will display a message prompting you to confirm that you want to update the firmware. Select “Yes” or “OK” to begin the installation process.
Wait for the Update to Complete: The update may take several minutes to install, depending on the size of the file and the speed of your device. During this time, do not turn off your GPS unit or remove the storage device, as doing so could cause the update to fail or damage the device.
Reboot the Device: Once the firmware update has been successfully installed, your GPS unit will likely reboot automatically. If not, you can manually restart the device.

6. Verify the Update

After the GPS unit reboots, it’s essential to verify that the firmware update has been successfully installed. You can do this by checking the device's settings:

Check Firmware Version: Navigate to the “Settings” menu on your Lowrance GPS unit and find the “About” section. Here, you should see the firmware version number listed. Confirm that it matches the latest version available on the Lowrance website.
Test the Unit: To ensure that the update didn’t cause any issues, test the GPS unit’s basic functions. Check if the maps are loading correctly, if the GPS signal is accurate, and if all other features are working properly.

Troubleshooting Tips for Lowrance GPS Map Firmware Update

While the process of updating your Lowrance GPS map firmware is straightforward, some issues may arise. Here are a few troubleshooting tips to help you resolve common problems:

Ensure Sufficient Battery Power: Before starting the update process, make sure your GPS unit has enough battery charge or is connected to a power source. A low battery could interrupt the update and cause errors.
Check the Storage Device Compatibility: If your GPS unit is not detecting the update file, ensure that the storage device (microSD card or USB drive) is compatible and properly formatted.
Avoid Interruptions During the Update: Never interrupt the update process, such as turning off the device or removing the storage device while the update is ongoing. Doing so can corrupt the firmware and render the device unusable.
Update Software Conflicts: If you encounter any issues after the update, such as slower performance or glitches, check the Lowrance website for any additional patches or fixes. Sometimes, minor follow-up updates are necessary to address initial bugs in the new firmware.

Conclusion

Updating the firmware on your Lowrance GPS map unit is a simple but essential task to ensure that your device remains up-to-date and performs optimally. Regular updates enhance features, improve map accuracy, and help maintain overall device reliability. By following the steps outlined above, you can easily update your Lowrance GPS unit’s firmware and enjoy a seamless navigation experience on the water or in the field. Just remember to back up your data, verify the firmware version, and never interrupt the update process to avoid any complications.
