FOR UPDATE:👉 CLICK HERE

Updating your Lowrance GPS can help keep your navigation system current with newer software, map information, and supported improvements. An outdated GPS may not have the latest available navigation data, while an updated system can provide a smoother experience and better compatibility with newer map products.

The update process can vary depending on your Lowrance GPS model, software version, map package, and available update method. This guide explains the general steps for updating a Lowrance GPS safely and correctly.

Check Your Lowrance GPS Model

Before beginning the update, identify your exact Lowrance GPS model.

Look for the model name or number on the device, product label, system information screen, or documentation. Different Lowrance models can have different update requirements, so this information is important when selecting an update.

Avoid downloading software or map files that are not intended for your specific device.

Check the Current Software Version

Before updating, check the software version currently installed on your Lowrance GPS.

Open the system information, settings, or device information section and locate the software version. The exact menu location may vary depending on the model.

Write down the current version so you can compare it with the version you install later.

Check the Current Map Version

If your goal is to update the GPS maps, check the map version currently installed as well.

A GPS software update and a map update are not necessarily the same thing. Software controls the operation of the device, while map updates provide newer geographic and navigation information.

Knowing the current map version helps you determine whether a newer map is available.

Confirm Update Compatibility

Before downloading anything, make sure the update is compatible with your Lowrance GPS model.

Different devices can support different software and map packages. An incompatible update may not be detected or may cause the installation to fail.

Check the requirements associated with the update and select the package that matches your device.

Prepare a Compatible Memory Card

Depending on your Lowrance GPS model, you may need a compatible memory card to transfer and install the update.

Check that the card has enough available storage and can be read correctly by your computer and GPS.

If the memory card contains important navigation information, back it up before using it for an update.

Back Up Important Navigation Data

Before performing a major update, consider backing up important data if your Lowrance GPS supports this feature.

Your saved information may include waypoints, routes, tracks, or other navigation details.

A backup can protect your information if the memory card needs to be formatted or the update process has to be repeated.

Keep your backup until you have confirmed that the updated GPS is working correctly.

Download the Correct GPS Update

After confirming your model and compatibility, download the appropriate Lowrance GPS software or map update using the supported update method.

Use a reliable internet connection during the download.

Some updates can be large, so allow the download to finish completely. Avoid closing the update process or disconnecting from the internet while the files are being downloaded.

Check the Downloaded Update Files

After downloading the update, make sure the required files are complete.

Do not rename or modify the files unless the instructions for your Lowrance model specifically require it.

If the update requires a particular folder structure, keep the files arranged correctly.

Incorrect file placement can prevent the GPS from detecting the update.

Transfer the Update to the Memory Card

If your Lowrance GPS uses a memory card for updates, transfer the required update files to the card according to the instructions for your model.

Wait until the transfer is completely finished before removing the card.

Use the computer's safe-eject option before disconnecting the memory card.

An incomplete transfer can cause the update to fail or remain undetected.

Insert the Memory Card Into the GPS

Insert the prepared memory card into the appropriate slot on your Lowrance GPS.

Make sure the card is inserted securely and in the correct position.

Turn on the device and give it enough time to detect the card and recognize the available update.

Start the Lowrance GPS Update

Depending on your model, the GPS may automatically detect the update or display an option to begin the installation.

Follow the instructions shown on the device screen.

If multiple update options are available, select the one that matches your device and the type of update you want to install.

Do not select an update intended for another Lowrance model.

Keep the GPS Powered

Make sure your Lowrance GPS has a stable power supply before beginning the installation.

A power interruption during an update can cause the process to fail or become incomplete.

If your GPS is installed on a boat, make sure the battery and power connection are stable.

Once the update begins, do not intentionally turn off the device.

Do Not Remove the Memory Card

If the update is being installed from a memory card, do not remove the card while the GPS is actively using it.

Removing the card during installation can interrupt the update and potentially cause additional problems.

Wait until the device confirms that the update has finished before removing the card.

Wait for the Installation to Finish

Allow the GPS enough time to complete the update.

The installation time can vary depending on the device, update size, memory card, and type of update.

Do not repeatedly press buttons or restart the device while the update is in progress.

If the progress appears slow, give it additional time before assuming that the process has stopped.

Restart the GPS if Required

After the update is completed, your Lowrance GPS may restart automatically.

If a normal restart is required, follow the instructions displayed on the screen.

Allow the device to load completely before checking the updated software or maps.

Verify the Software Update

After restarting, open the system information section and check the software version.

Compare it with the version you intended to install.

If the new version appears, the software update was successfully applied.

If the old version remains, check the update files, memory card, and compatibility before attempting the process again.

Verify the Map Update

If you updated the maps, check the map information after installation.

Confirm that the new map version is displayed.

Open the navigation screen and make sure the map loads properly.

Check commonly used areas to ensure that the navigation information is available as expected.

Check Your Saved Navigation Data

After updating the GPS, verify that your saved waypoints, routes, tracks, and other navigation information are still available.

If you created a backup before starting the update, keep it until you are satisfied that everything is working normally.

This provides additional protection if you need to restore information later.

What to Do if the Update Fails

If your Lowrance GPS update fails, begin by checking the basic requirements.

Confirm that the update is compatible with your exact GPS model. Check the memory card, available storage, internet connection, downloaded files, and power supply.

If the update file appears incomplete, download it again. If the memory card is not recognized, check its compatibility and condition.

Also note any error message displayed by the device because it may provide useful information about the cause.

Keep Your Lowrance GPS Updated

Regularly checking for compatible software and map updates can help keep your Lowrance GPS current.

However, always confirm that an update is designed for your specific model before installing it.

Map updates and software updates serve different purposes, so determine which type of update your device requires before beginning the process.

Final Thoughts

Updating a Lowrance GPS is easier when you prepare the device carefully and use the correct update files. Start by identifying your exact model, checking the current software and map versions, and confirming compatibility.

Prepare a compatible memory card when required, download the complete update, and transfer the files correctly. During installation, keep the GPS powered and avoid removing the memory card or interrupting the process.

After the update finishes, verify the new software or map version and check your saved navigation information. These simple steps can help you update your Lowrance GPS successfully and keep your navigation system ready for use.
