New Software Update Available for Simrad® Displays
Simrad® Marine Electronics has released a powerful new software update for select Simrad® chartplotters and fishfinders—introducing a range of new features to elevate your experience on the water.
If you’re running an NSX®, NSX® ULTRAWIDE, or the new NSS® 4 device, this update unlocks even more capability for your display.
Thinking about upgrading? Now’s the perfect time. The update brings brand-new functionality to NSX users, along with some added enhancements for NSS 4 devices.
Here’s what’s new...
Custom Sonar Color Palettes
Fine-tune your view with custom color palettes for your echosounder display. Make it your own to help distinguish fish, structure, and bottom with greater clarity.

Waypoint Fish Tagging
Tag your catch! Add fish species icons to waypoints so you can filter and return to your favorite spots by species.
Enhanced Sonar Support
Now compatible with Simrad® network sonar modules including the S5100, S3100, and SonarHub®, so you can connect and see more of what’s below.
S3100H Heave Compensation
Pair with the new S3100H sonar module and enable heave compensation to minimize wave motion interference. That means more accurate fish arches and bottom readings—especially in rougher water.
Multiple Sonar Views
Display multiple sonar instances from any connected source. The NSS® 4 supports up to four, and NSX™ supports up to two—giving you a more complete view of what’s happening beneath the surface.
Smarter Navigation Menus
Enjoy quicker access to key functions like lightning-fast autorouting and simple “stop navigation” commands with an updated chart menu design.
Heat Trails – NSS 4 Only
Your vessel track now captures more than just time and position. Visualize your speed, temperature, and other data streams directly on your chart with color-coded trails.

Updated Fuel App
Now you can set the number of engine instances from within the settings under Boat Details—great for multi-engine setups.
Improved Waypoint Management
Filter waypoints by location directly on the chart, making it easier to manage your favorite fishing or navigation points.

C-MAP® Genesis Social Map Layer Update
Access the most recent community-sourced depth maps with enhanced display and usability.
Expanded Trolling Motor Support
More integrated control and compatibility for trolling motors, right from your Simrad® display.
IP Camera 4-Way Split View – NSS 4 Only
Get a better view around your vessel with new support for four simultaneous IP camera feeds.

New Radar Control Options
