How to Update Your Simrad GPS: A Complete Step-by-Step Guide for Optimal Performance

Keeping your Simrad GPS updated is one of the most important things you can do to ensure accurate navigation, better functionality, and the latest chart data while you’re out on the water. Whether you use your Simrad device for fishing, sailing, or cruising, regular software and chart updates enhance your overall experience by improving performance, fixing bugs, and adding new features. In this detailed guide, we’ll walk you through everything you need to know about updating your Simrad GPS, from preparation to completion.

Why Updating Your Simrad GPS Matters

A Simrad GPS or multifunction display (MFD) is more than just a navigation tool—it’s the command center of your vessel. Like any advanced electronic system, it relies on software that evolves over time. Updates are released periodically to address issues, enhance compatibility with new accessories, and improve charting accuracy. Here are some key reasons why updates are essential:

1. Improved Accuracy: Updates often include enhancements to GPS precision and chart data, helping you stay on the safest and most efficient routes.

2. New Features: Software updates can add new tools or functions, such as improved sonar visualization, touchscreen enhancements, or expanded connectivity options.

3. Bug Fixes: Every piece of software occasionally develops glitches. Updates correct these problems, ensuring smoother operation.

4. Compatibility: As new Simrad accessories and networking options become available, updates ensure your system remains compatible.

5. Safety Enhancements: Improved alarms, warnings, and navigational safety features are often included in updates, making your boating experience safer.

Before You Begin: Preparation Checklist

Before starting the update process, it’s important to prepare properly. A few minutes of preparation can save you a lot of frustration later.

1. Identify Your Model: Check which Simrad model you own—such as GO, NSS, NSO, or Cruise—because update procedures may vary slightly between models.

2. Check Current Software Version: In your Simrad menu, go to Settings > System > About to see the current software version. This helps determine whether you actually need an update.

3. Stable Power Source: Ensure your boat’s power supply or battery is steady. Losing power mid-update can cause system errors or data loss.

4. Backup Your Data: Save waypoints, routes, and preferences before performing an update. Use a microSD card or a USB drive to back up your data.

5. Prepare a MicroSD Card: Most updates are done through a microSD card with at least 8 GB of free space. Make sure it’s properly formatted and compatible with your Simrad device.

Step 1: Download the Update File

While you won’t find direct download links here, the general process involves visiting the official Simrad software update section from a computer. Using your model’s name, locate the latest available software version. Once you’ve found the correct update, download the file to your computer.

After the download finishes, extract or unzip the file if necessary. You’ll usually see a folder or file with an extension like .upd or .swup, which is the update package your Simrad device will recognize.

Step 2: Transfer the Update to a microSD Card

Insert your microSD card into your computer. Then copy the update file or folder directly onto the card. Avoid placing it inside any subfolders—your Simrad device should find it easily at the root level of the card. Once the transfer is complete, safely eject the microSD card from your computer.

Step 3: Insert the microSD Card into Your Simrad Device

With your boat’s power on and your Simrad GPS system running, insert the microSD card into the device’s card slot. The system should automatically detect the update file. A notification or message usually appears, prompting you to begin the update process.

If no message appears, navigate to Settings > System > Files or Storage to locate and manually select the update file.

Step 4: Install the Update

Once the system detects the update file, select Install or Update Software. Your Simrad GPS will begin installing the update, which may take several minutes. During this time:

• Do not turn off the power.

• Do not remove the microSD card.

• Do not press any buttons unless prompted.

The screen may go blank or restart a few times—this is normal. The update is complete once the system restarts and returns to the main interface.

Step 5: Verify the Installation

After the update finishes, it’s important to confirm that everything installed correctly. Go to Settings > System > About again and check the software version. The version number should match the one from the update package.

You should also check that your waypoints, routes, and settings were preserved. If anything is missing, you can restore your backup from the microSD card.

Step 6: Update Charts and Maps

Software updates improve your GPS performance, but charts and maps must also be kept up to date. Updated chart data ensures that navigation markers, depths, coastlines, and other essential features are current.

Chart updates are usually downloaded from the same source where you obtained your software update. Use your microSD card to transfer the chart files, then load them into your Simrad system. After installation, check that your charts display correctly and contain the newest data.

Step 7: Test and Calibrate Your System

Once your software and charts are up to date, take a few minutes to test your system:

• Zoom in and out of maps to check responsiveness.

• Confirm that GPS positioning is accurate.

• Test connectivity features like radar, sonar, or autopilot (if applicable).

• Recalibrate any sensors or compasses if the system requests it.

Doing a quick test run before heading out for a long trip ensures that everything functions as expected.

Troubleshooting Common Update Issues

Even though updates usually go smoothly, issues can occasionally arise. Here are some common problems and solutions:

• The device doesn’t recognize the update file: Make sure the update file is located at the root level of the microSD card and not inside a folder. Also, verify that the file matches your device model.

• Update process freezes or fails: If the update stops partway through, restart the system and try again with a freshly formatted card.

• System won’t start after update: In rare cases, performing a hard reset or reinstalling the previous version can resolve this. Consult your owner’s manual for reset instructions.

• Missing data: Restore your backed-up routes and waypoints from the microSD card.

Tips for Maintaining Your Simrad GPS

1. Update Regularly: Check for new updates at least twice a year, especially before boating season.

2. Keep Clean Power: Ensure your battery and electrical connections are stable to prevent corruption during updates.

3. Use Genuine Accessories: Non-certified microSD cards or cables can cause compatibility issues.

4. Record Settings: Take photos of your settings before an update—this makes it easier to restore configurations if needed.

5. Stay Informed: Monitor manufacturer announcements for any important update notices or feature releases.

Conclusion

Updating your Simrad GPS is a simple yet vital process that ensures your navigation system performs at its best. By following the steps outlined in this guide—preparing properly, backing up your data, and carefully installing updates—you can keep your device reliable, accurate, and ready for any voyage.

Regular updates not only enhance safety and functionality but also help you get the most from your investment in advanced marine technology. A well-maintained Simrad GPS means smoother navigation, fewer surprises, and more time enjoying the open water with confidence.
