Furuno NavNet TZtouchXL Black Box Chartplotter

Description

The Furuno NavNet TZtouchXL Black Box is designed for a helm where the display and processor need to be separated. It can drive an external 16-, 19-, 22-, or 24-inch multi-touch monitor, making it useful for custom glass bridge layouts, commercial boats, and yachts with unusual console designs. It is a navigation controller, not a screen-included chartplotter.

The TZTBBX uses a hexacore processor and supports TZ MAPS, C-MAP, and raster chart formats. Three Ethernet ports, HDMI input/output, USB, NMEA 2000, NMEA 0183, and WiFi allow the black box to sit out of sight while the display is mounted where the operator needs it. Sonar requires a DFF1-UHD, DFF3-UHD, or DFF3D module. The processor unit is IP22, so it must be mounted in a protected location rather than exposed on deck.

Key Features

• Black-box chartplotter design – Lets the display be mounted separately from the processor.
• External monitor support up to 1920 x 1080 – Gives the installer freedom to choose a compatible screen.
• TZ MAPS, C-MAP, and raster support – Provides chart-format flexibility.
• DFF1-UHD, DFF3-UHD, and DFF3D compatibility – Allows external sonar expansion through the Furuno network.
• Three Ethernet, HDMI input/output, USB, NMEA 2000, NMEA 0183, and WiFi – Supports a custom vessel installation.

Who Is This For?

This black-box marine chartplotter suits custom yacht helms, commercial vessels, and boats where the processor must be hidden or separated from the monitor. It is not ideal for a buyer wanting a simple all-in-one MFD or an exposed deck installation; the processor carries an IP22 rating.

Compatibility

Confirmed compatibility includes external 16-, 19-, 22-, and 24-inch multi-touch displays, DFF1-UHD, DFF3-UHD, DFF3D sonar modules, TZ MAPS, C-MAP, raster charts, NMEA 2000, NMEA 0183, three Ethernet ports, HDMI input/output, USB, and WiFi. No specific radar, autopilot, or transducer model is named. No named incompatible system was provided.

Warranty & Support

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

The TZTBBX is the most installation-flexible product in this group because the processor can be hidden and the monitor chosen separately. That flexibility comes with a real trade-off: you must supply a compatible display, protect the IP22 processor from weather, and add a DFF sonar module if fishfinding is needed. Choose it for a custom glass bridge, not a straightforward MFD replacement.
