Simrad NSO evo3S MPU 19 Single System

The Simrad NSO evo3S MPU 19 Single System (MPN 000-15116-001) is the modular black-box version of Simrad's flagship multifunction system. Where the integrated NSO evo3S 24 puts the processor behind the display, the MPU architecture separates the two: the Marine Processor Unit (MPU) lives in the electronics bay or under-helm, and the 19-inch MO19-T monitor sits flush at the helm with nothing behind it but cable. For installs where the helm needs to stay clean (low-profile glass dashboards, custom helm builds, or simply better heat dissipation for the processor), the modular approach is the right architecture.

What's in the box. The Simrad NSO evo3S Marine Processor Unit with embedded Insight cartography for the Americas. The MO19-T 19-inch widescreen high-bright multi-touch monitor. The OP50 wired remote controller for keypad operation. The MI10 dashmount microSD card reader for chart updates. The GS25 GPS antenna with built-in rate compass for position and heading reference. The HDMI monitor video cable (3m) and NMEA 0183/touch serial cable (2m). That's the kit that gets you from boxed components to a commissioned single-display helm.

Why MPU instead of integrated. Three reasons. First, helm aesthetics. The MO19-T monitor is a clean glass panel with no processor bulk behind it, so the dash stays low-profile and modern. Second, install flexibility. The MPU mounts wherever you have ventilation and access, the monitor mounts where you want it visible. Cable lengths between the two can be longer than you'd get with an integrated display. Third, heat and serviceability. The processor isn't sealed behind a touchscreen, so it runs cooler and is easier to service or upgrade independently of the monitor. For custom helm builds and luxury yacht installs, the modular architecture is the standard choice.

Dual quad-core processing. The MPU contains dual quad-core processors with a dedicated processor per monitor output. Even though the Single System is configured with one monitor, the dual-output architecture is there. That means chart redraws are smooth, multi-panel layouts switch instantly, radar overlay updates without lag, and the autopilot interface responds without input delay. For helm operators who use the MFD as the primary instrument, the responsive performance is what makes the system usable under operational pressure, not just under demo conditions.

Display capability. The MO19-T 19-inch widescreen monitor delivers Full HD resolution at high brightness, with multi-touch input that handles chart panning, waypoint creation, and menu navigation as naturally as a tablet. The wide viewing angles keep the screen readable from any helm position, including with polarized sunglasses. For boats where the display is referenced from multiple positions (helm seat, standing, navigator station), the wide angles eliminate the head-bobbing that plagues off-axis MFD viewing.

Cartography compatibility. Embedded Insight cartography for the Americas means most U.S. and Canadian boats are usable from first power-up. Support for C-MAP MAX-N, Navionics, Insight Genesis, and NV Digital raster charts means you can add cartography for any cruising region or use the chart format you already have invested in. For owners who already have a C-MAP or Navionics card library, you don't have to start over with this system.

Tablet control. The MPU connects to iPad or Android tablet via Simrad's mobile app for wireless remote operation. You can view the chart, change waypoints, control the autopilot, and operate the entire MFD interface from anywhere on the boat. For larger vessels where the captain might want to monitor from the flybridge or aft deck, or for owners who simply prefer the larger tablet view in cabin while underway, the wireless control is operationally useful.

Autopilot integration. Full NSO evo3S autopilot control via compatible Simrad autopilot computer. Steering modes include Auto, Nav, No Drift, Follow Up, Non-Follow Up, Wind, Wind Nav (sailboats), and turn patterns (U-turn, Spiral, C-turn, Zig-zag, Square, Lazy S, depth contour tracking). For the integrated autopilot user interface, the optional OP-40 remote adds dedicated autopilot controls beyond what the OP50 wired remote handles.

Radar, sonar, and audio integration. NSO evo3S MPU connects to Simrad Halo Pulse Compression Radar, Broadband Radar, and HD Pulse Radar. Sonar from S5100 CHIRP, SonarHub broadband, and StructureScan3D for forward-looking and side imaging. Performance Module compatibility for expanded sonar capability. FusionLink audio integration. AIS via NMEA 2000 or NMEA 0183. The MPU is the central piece of a complete Simrad helm electronics stack.

Install considerations. The MPU is a black-box that mounts in any ventilated under-helm location with adequate cable routing to the monitor (typically 3m HDMI included, longer runs available). The MO19-T monitor is panel-mount at the helm. Power is 12V or 24V DC. Total install is a marine electronics installer day for a clean modular helm, with extra time for custom dash work if you're starting from scratch on a refit. Not casual DIY because the MPU-to-monitor cable runs, network integration, and autopilot commissioning all need professional setup.

Why pay this much. The MPU architecture is the choice for custom helm builds where the monitor needs to stay clean and the processor lives somewhere with proper ventilation. The dual quad-core processing delivers responsive performance even under heavy multi-tasking. And the bundled single-system pack (MPU + monitor + remote + GPS + card reader + cables) means the install is complete, not a starting point. For owners building or refitting a serious modular helm, the NSO evo3S MPU 19 Single System earns its position.
