The Raymarine C120W is the midsized unit in the newly released C-series widescreen network capable multi-function chartplotter lineup.
The C120W ships with the display unit, a sun cover, documentation, and cabling. The display has an internal GPS sensor and can connect to an optional external GPS antenna if desired.

It also comes with preloaded cartography covering U.S. coastal waters.
The C120W can also use Navionics Gold or Platinum cards in its single front panel card slot. When so equipped the unit will show 3D navigation and high-resolution photo coverage of certain areas.
The display unit is quite large, it measures 15-inches wide, 10-inches high, and about 4.5-inches deep. Our test unit was loaded with software version 1.12.
We mounted the Raymarine C120W to our test rig using an optional metal trunion bracket. Normally a display this big would be flush mounted in a panel. Hardware to flush mount is supplied.

Connectivity
The power supply, which can be either 12- or 24-volts DC, NMEA0183 data, and a video port all pass through a single cable that attaches to the case back with a twist lock connector.
The case back also has two SeaTalkhs network ports that allow the C120W to connect to another C-series widescreen display, radar, AIS, or a black box sounder.
The case back has a fourth cable connection for SeaTalkng, an N2K compliant network. The C120W has a three of NMEA0183 ports built-in.
Port one is a normal NEMA0183 input/output port. Port two is also input/output capable and high-speed, meaning it can operate at 38,400 bauda necessity today for anyone looking to connect a high-speed device like AIS to this unit. Port three is normal speed input only.
New Autopilot Integration
We didn’t get to test this funtion but Raymarine Marketing Manager, Jim McGowan, gave us the briefing. Here it is. The Raymarine C120W and other C-Series Widescreen systems now feature SeaTalk autopilot integration as a standard feature. This makes it much more convenient to use your Raymarine autopilot navigation mode.
In the past, to make the autopilot track to a route or waypoint on the chartplotter, it was necessary to first activate the destination on the chartplotter, then activate the navigation mode on the autopilot, then confirm the destination on the autopilot too. This required several button presses on each device, and depending on the proximity for your chartplotter to your autopilot control head, may require several trips across the boat or up and down a ladder.
With the latest software in your Raymarine Multifunction Display, the MFD is now totally autopilot aware. We have even added an autopilot status icon to the MFD’s data bar to support this.
Now, whenever you use the Goto Waypoint, or select the option to follow a route, the chartplotter displays a prompt asking if you would like it to activate the autopilot and track to the destination. All of the button presses required to make this
