Furuno Navnet TZ Touch Black Box - No Display TZTBB

The Furuno Navnet TZ Touch Black Box (TZTBB) is the processing powerhouse behind modern marine navigation systems, designed to integrate seamlessly with Furuno's multi-touch display options. This black box unit houses the core electronics and computational architecture that drives the TZtouch platform, enabling real-time chart plotting, sounder integration, and autopilot control across both offshore and recreational fishing vessels. Unlike all-in-one display units, the TZTBB separates processing from the screen, allowing captains to position displays optimally in the wheelhouse or control station while maintaining full system performance.

The unit weighs 31 lbs and measures 17 x 17 x 21 inches—compact enough for retrofit installations on existing vessels while robust enough to handle the electrical demands of networked marine electronics. The black box architecture supports wireless connectivity to tablets and smartphones, enabling remote monitoring and control from anywhere on deck via compatible iOS apps. Built-in access to Marine Weather Forecaster provides unlimited, worldwide weather data updated 24/7 at no additional subscription cost—critical functionality for offshore anglers planning multi-day trips or coastal operators monitoring approaching systems. The modular design means you choose which touch display size and resolution matches your wheelhouse setup, from compact 7-inch screens to larger 19-inch units, without replacing the core processing unit.

This system suits both weekend fishermen running smaller center consoles and serious offshore operations managing complex sounder arrays and chartplotter networks. Vessel operators upgrading from legacy standalone GPS or echo sounder systems will find the TZtouch integration consolidates multiple instruments into one ecosystem, reducing cable clutter and creating a unified interface. The black box format also serves boat builders and refurbishment projects where component flexibility is essential. Compatibility with Furuno's broader marine electronics ecosystem—including their sounder modules and autopilot options—makes the TZTBB a foundation for systems scaling from basic navigation to fully integrated bridge automation.
