Keeping your Lowrance navigation system updated can help improve navigation performance, add new features, and keep maps and software current. Updates may include system software, navigation maps, charts, or other improvements. The exact process can vary depending on your Lowrance device and the type of update required.

Check Your Lowrance Model

Before starting an update, identify your exact Lowrance navigation system model. Check the device settings, product label, or documentation to find the model name and current software version. Using the correct update for your device is important.

Check the Current Software Version

Open the system information or settings menu on your Lowrance device and check the installed software version. Comparing the current version with the latest version available for your model can help you determine whether an update is required.

Prepare an SD Card

Many Lowrance navigation systems use an SD or microSD card for software and chart updates. Use a compatible card with enough available storage space. Back up important files on the card before using it for an update.

Download the Correct Update

Use the official Lowrance support or update resources to find the appropriate software or navigation update for your specific device. Carefully select the correct model before downloading any files.

Copy the Update to the Card

After downloading the required update, follow the provided instructions to place the update files on the compatible SD card. Make sure the files are copied correctly and that you do not accidentally modify or rename required update files.

Insert the Card Into Your Device

Turn on your Lowrance navigation system and insert the prepared SD card into the appropriate card slot. The device may recognize the available update automatically or provide an update option through the settings menu.

Start the Navigation Update

Follow the instructions displayed on your Lowrance screen to begin the update. Confirm that you want to install the available software or navigation update when prompted.

Keep the Device Powered On

Do not turn off the navigation system or remove the SD card while the update is running. Interrupting the installation can cause problems with the device software. Make sure the device has a reliable power source throughout the update process.

Restart the Navigation System

After the update finishes, the system may restart automatically. If prompted, allow the device to restart and complete any remaining installation steps. Once it starts again, check the software version to confirm that the update was installed.

Check Navigation Maps and Charts

If you updated navigation maps or charts, open the relevant navigation features and verify that the updated data is available. Make sure the map information appears correctly before using the system for navigation.

Troubleshoot Update Problems

If the update does not appear, check that the downloaded files match your exact Lowrance model and that the SD card is compatible and properly prepared. If the installation stops or displays an error, review the official update instructions and avoid repeatedly interrupting the process.

Conclusion

Updating a Lowrance navigation system involves checking the device model and software version, preparing compatible storage media, downloading the correct update, and following the on-screen installation instructions. Keeping the system powered during the process and verifying the software or map version afterward can help ensure a successful update.
