SI-TEX Explorer NavPro w/Wi-Fi & GPK-11 GPS Antenna

The SI-TEX Explorer NavPro Bundle is a black-box chartplotter for custom helms where the owner wants to use a separate HDMI display. It includes the GPK-11 GPS antenna, so the position source is part of the package. This approach works well in compact panels, hidden equipment lockers, and custom bridge layouts where a conventional all-in-one chartplotter does not fit.

The controller sends video to an external monitor at up to 1080p, leaving the buyer free to choose the screen size and mounting location. C-MAP 4D and MAX compatibility handles charting, while two NMEA 0183 ports and NMEA 2000 make it useful on boats with mixed electronics. Optional network sonar can be added later, but this package is chartplotter-focused. The key installation point is simple: make sure a compatible HDMI monitor is already part of the helm plan.

Who Is This For?

This black-box marine chartplotter suits custom helms, workboats, and boats with an existing HDMI monitor. It is not ideal for a buyer wanting a built-in screen or a complete fishfinder, because the display is external and sonar is optional.

Warranty & Support

SI-TEX provides a 2-year standard warranty. The supplied specifications do not state exclusions or service procedures.

The Explorer NavPro Bundle is for a custom installation, not a plug-and-play dashboard. Its advantage is flexibility: use the monitor size and location that suits the boat. The trade-off is that you must supply and install the external display. Choose it for a custom helm where a normal fixed MFD does not make sense.
