Chart-Northstar's 32 MB chart gets you started for global navigation, or install C-Map's NT MAX technology for detailed chart data, value-added port info and land detail.

Sonar-The Northstar M121 is equipped with a powerful 1 kW (RMS) sounder that automatically adjusts the output power (1 kW or 600W) to match the wattage of the transducer. No black box required,just plug the transducer of choice directly into the M121 and you're up and running.

Fuel Management-With the Northstar M121, you have on-demand access to your engine's performance data as well as SmartCraft management for Mercury engines.

Video-For the first time, Navman brings video to your helm. Hook a security camera up for live deck monitoring, engine room surveillance or underwater views. Or even run a DVD player or camcorder into the M121 for entertainment†.

RADAR
Northstar High Definition Digital Radar brings advanced signal processing, better target presentation and better clutter rejection with your optional Northstar Digital Radar system.

SONAR
Equipped with a powerful 1kW (RMS) sounder that automatically adjusts the output power (1kW or 600W) to match the wattage of your transducer. No separate sounder processor is required. Simply plug the transducer of your choice into the M121 and you're up and running.

A.I.S.
Optional Automatic Identification System receivers display vital vessel information from registered vessels on the chartplotter screen.

FUEL MANAGEMENT
On-demand access to your engine's gasoline performance data, as well as SmartCraft™ management for SmartCraft-enabled Mercury, Mariner or MerCruiser engines (optional fuel kit/SmartCraft™ gateway required).

VIDEO (PAL/NTSC)
Northstar brings video to your helm. Connect a camera for deck monitoring, engine room surveillance, even underwater views. Or connect a DVD player or camcorder for entertainment at your helm (a separate audio output system is required for sound).
