How to Update Hummingbird Xplore Software: Easy SD Card Method

Keeping your fishfinder updated ensures you’re running the latest features, fixes, and performance improvements. For Humminbird Xplore units, software updates are straightforward if you have the right tools and follow the correct process. In this guide, I’ll walk you step by step through updating your Xplore unit using an SD card. I’ll also include extra tips to avoid common mistakes and explain why keeping your system current is critical for sonar performance.

Why Software Updates Matter

Fishfinder manufacturers regularly release software updates to fix bugs, improve compatibility, and add new features. For anglers, that can mean sharper imaging, smoother screen performance, or even entirely new menu options. Ignoring updates may leave you with outdated performance and, in some cases, glitches that have already been corrected.

What You’ll Need Before You Start

Before heading out to the boat, gather the following:

• A computer with an SD card slot – This is required to download the update.

• An microSD card with SD card adapter– Humminbird Xplore units accept up to 32 GB. 

• Speed Class 10 card – Faster cards ensure smooth file transfers and reduce the risk of corrupted downloads.

• A stable power supply – The unit must remain powered during installation.

Tip: Never attempt an update with a partially charged battery. If the power cuts out mid-update, the software may fail, forcing a reset or factory service.

Step 1: Download the Software Update

1. On your computer, open your web browser and search for “Humminbird Xplore software update.”

2. Navigate to the official Humminbird site. Make sure you select the update that matches your exact unit (for example, Xplore 10 MSI Plus).

3. Download the software update file. Humminbird usually provides two options: a software-only download and a download with instructions. Grab the software file directly.

Once downloaded, the file will appear in your computer’s “Downloads” folder.

Step 2: Transfer the Update to Your SD Card

1. Insert your microSD card (in an adapter, if needed) into the computer’s card slot.

2. Open the Downloads folder and locate the update file.

3. Drag and drop the file directly onto your SD card.

4. Safely eject the SD card. On Windows, right-click and choose “Eject.” On Mac, click the eject arrow.

Why ejecting matters: Removing the card without ejecting can corrupt the update file, which may prevent the unit from reading it.

Step 3: Prepare Your Fishfinder

Before inserting the SD card into your Humminbird Explorer:

• Remove any other cards, such as the LakeMaster mapping card that comes pre-installed. Updates will not run properly if more than one card is in the slot.

• Keep the unit powered on throughout the process. Do not disconnect power or shut down the system.

Step 4: Install the Update on the Unit

1. With the Xplore unit powered on, insert the SD card.

2. The unit will automatically detect the new software. A message will pop up asking if you’d like to install it.

3. If you want to update immediately, select Install.

4. If you prefer to do it manually, press the Home button, go to Tools > Software Update, and select the new version from the list.

During installation, the unit will display a progress amount. This process can take several minutes. Do not remove the SD card or power down the unit until the update is complete.

Step 5: Verify the Update

After installation, check the software version:

• Go to Home > Tools > Software Update.

• The “Current Version” should now match the version on your SD card.

Updates typically restore the unit to factory defaults, meaning your settings may be reset. This is normal.

After the Update: Restoring Your Settings

Since software updates restore defaults, take time to re-enter your preferred sonar and imaging settings. This step is essential because your performance on the water depends heavily on how your unit is configured.

Tips for a Smooth Update

• Keep the update file alone on the card. Avoid having extra files or folders.

• Check your software version beforehand. This prevents unnecessary updates.

• Update regularly. Garmin, Humminbird, and Lowrance all release updates multiple times per year. Staying current ensures you benefit from every improvement.

• Back up waypoints first. If you rely on marked spots, export them before updating in case of a reset.

Alternative: Updating via the Humminbird One-Boat Network App

While this guide focused on the SD card method, Humminbird also allows updates through the One-Boat Network app. By connecting your unit to a smartphone, you can download and install updates wirelessly. This is convenient if you don’t have access to a computer with an SD card slot.

However, many anglers prefer the SD card method because it’s more reliable and less dependent on Wi-Fi signal strength.

Final Thoughts

Updating your Humminbird Xplore is simple once you know the process. With just a computer, a properly formatted SD card, and a few minutes of time, you can ensure your fishfinder is running the latest software. Each update not only stabilizes performance but often unlocks new features and makes your sonar readings clearer.

Whether you’re chasing bass in shallow timber or scanning offshore ledges for schools of baitfish, staying up to date gives you the best chance of success on the water.
