Furuno NavNet 3D MFD12 Review

Furuno NavNet 3D is the latest iteration of this well-known marine electronics company’s network operating system. I’ll be reviewing the system with a 12-inch multi-function display unit.

The 12-inch MFD package ships with the display unit, metal mounting bracket, user’s handbook, installation guide book, flip-card operators’ guide, and a computer disk with the full 262-page operator’s manual.

An 8-inch NavNet 3D MFD is also available. The two available NavNet 3D displays are technically known as the NavNet 3D MFD12 and MFD8.

Our MFD12 test unit is brawny and demonstrates the robust construction we’ve come to expect from Furuno. The display front panel measures 15.6-inches wide by 10-inches wide; unit depth is 5.2-inches.

Normally a unit of this size and sophistication would be panel mounted. A removable front bezel provides access to mounting holes that secure the unit for flush mounting. We used the accompanying heavy-duty metal gimbal bracket to mount the MFD12 to our test rig.

One thing you’ll notice right away is the time this unit takes to boot up. During my review it took, on average, about two minutes to get everything cranked up.

Connectivity

When connected to the appropriate optional sensors a NavNet 3D MFD will interface with a GPS sensor, radar, black box fishfinder, AIS, Sirius weather receiver, and video.

Multiple NavNet 3D display units can share information via high-speed Ethernet. A USB mouse can be added too. These display units will also interface with NMEA0183 devices with support for data transfer rates of up to 38,400 baud. They will also couple to a NMEA2000 network.

I connected a Furuno GP330B GPS sensor via NMEA2000 to the MFD12 for this test. NavNet 3D components will operate with either 12- or 24-volt DC electrical system.

I measured the power usage of the MFD with a GPS sensor connected at about 2.7 amps. Selecting sleep mode turns off the display screen and drops the power usage to about 1.3 amps.
