SI-TEX 10 Chartplotter System w/Internal GPS & C-MAP 4D Card

The SI-TEX NavPro 10 is a stand-alone marine chartplotter for a helm that needs a larger, bright chart screen without adding fishfinder hardware. Its 10-inch IPS display, internal GPS, and included C-MAP 4D card make it a practical choice for coastal cruisers, workboats, and fishing boats where navigation is the priority and sonar is handled elsewhere.

The 1024 x 600 screen gives more room for routes and chart detail than compact 7-inch displays, while 1000-nit brightness helps when the sun is coming through the windshield or across an open console. It accepts 10-35V DC, which suits both 12V and 24V boats. NMEA 2000 and NMEA 0183 make it useful around newer and older marine electronics, but sonar requires a separate external module.

Who Is This For?

This standalone marine chartplotter suits coastal cruisers, workboats, and fishing boats that already have separate sonar equipment. It is not the right choice for someone wanting an all-in-one fishfinder, because sonar needs an external module.

Warranty & Support

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

The NavPro 10 is a straightforward chart-first option for a boat that does not need bundled sonar. Its main advantage is the included C-MAP 4D card, internal GPS, and support for both NMEA standards. The trade-off is clear: it is a navigation display, not a self-contained fishfinder system.
