NSO® 4 is designed for larger, high-performance vessels that require an advanced, fully integrated marine electronics system. It’s ideally suited for large center consoles, sportfishing yachts, and luxury yachts, but is not limited to these applications and can be used on any vessel that supports larger display formats.
Acting as the heart of the vessel and the command center of the helm, NSO® 4 allows boaters to build a customized system for any offshore adventure—whether fishing, cruising, or entertaining—bringing radar, sonar, autopilot, engine integration, and multi-display control together into one powerful, centralized solution.
NSO® 4 is built for multi-display helm configurations and can connect to up to 12 additional displays running the NEON™ operating system, including Simrad® NSX®, NSX® ULTRAWIDE, NSS® 4, and other NSO® 4 units. This flexibility allows boaters to create customized helm stations across multiple locations on the vessel, while maintaining seamless visibility, control, and system integration throughout.
NSO® 4 is designed exclusively for flush helm and dash installation and does not support bracket mounting. Its refined, edge-to-edge glass design is intended to deliver a clean, integrated look at the helm.
Installation is simplified through a new rear-mount system that replaces traditional multi-piece brackets with a streamlined, tool-free solution. Pre-installed mounting arms rotate and lock into place using a simple push–twist–tighten action, enabling faster installs—including blind, single-handed installations in tight dash spaces. The result is reduced installation time, improved serviceability, and a more secure, professional finish.
Note: Detailed installation dimensions, spacing requirements, and cutout specifications are provided on the NSO® 4 specifications page.
NSO 4 is designed to work exclusively with C-MAP® X-gen charts. Look for charts with an “X” next to them, such as C-MAP® DISCOVER® X and REVEAL® X.
If you're using third-party charts, make sure to get a chart card specifically for NSO 4 (NEON™ OS devices). Don't hesitate to reach out to your chart provider for guidance on the best card for your needs.
Compatible charts: C-MAP® DISCOVER® X and REVEAL® X, CMOR Mapping, Standard Mapping, StrikeLines and more to come.
Navionics is not supported.
NSO 4 seamlessly integrates with a variety of Simrad® products, including:
