Overview

The Garmin 010-02677-00 is a GPSMAP 9500 black box chartplotter with a worldwide basemap that runs a full helm on external monitors, with no built-in display. It powers from 10 to 32 Vdc for 12V and 24V systems, uses a 4 A fast-acting fuse, and carries an IPX7 water rating for incidental exposure on board.

Video is output over HDMI OUT (required for operation) and touchscreen control can be added through USB when used with a compatible monitor. The unit supports Garmin BlueNet networking, NMEA 2000, NMEA 0183, and J1939 engine integration, so it can sit at the center of a multi-screen system with connected sonar, radar, cameras, autopilot, sensors, and digital switching. Chart and mapping upgrades use an external card reader (not included), and the platform supports Garmin Navionics+ and Garmin Navionics Vision+ cartography.

Key features

• Black box chartplotter with HDMI OUT to drive an external monitor (HDMI OUT is required for the unit to function)
• Touchscreen support when paired with a compatible monitor using HDMI for video and USB for touch data
• Two HDMI inputs for external sources: HDMI IN 1 supports up to 4K at 60 fps; HDMI IN 2 supports up to 4K at 30 fps
• Composite video input via CVBS IN (BNC) plus an audio out connection for system audio routing
• Power input from 10 to 32 Vdc with a 4 A, 42 V fast-acting fuse specification
• IPX7 water rating and a housing built from polycarbonate plastic with die-cast aluminum
• Garmin BlueNet networking for building multi-device helms, with up to 10 times faster networking speeds and gigabit-capable connectivity
• NMEA 2000 and NMEA 0183 support for common marine sensors, radios, and autopilot integration, plus J1939 receive support for compatible engine data
• OneHelm integration support for compatible monitoring, control, and automation systems, including EmpirBus-based setups
• Wi-Fi, Bluetooth, and ANT connectivity for wireless updates with the ActiveCaptain app and compatible device pairing
• External chart card support through a compatible USB card reader (not included)

Display and control options

This system is built around your choice of display. HDMI OUT carries the video feed to a monitor, and a touchscreen monitor can control the system when its USB connection is run back to the unit. If your monitor is not touch-capable, the system can be operated with compatible remote input hardware on the network, which keeps the black box itself tucked away while the helm stays usable in rough water.

Networking and system integration

For bigger helms, Garmin BlueNet makes it practical to link chart views, sonar pages, radar overlays, cameras, and video sources across multiple stations without the lag you feel on slower networks. NMEA 2000 and NMEA 0183 connections cover most common marine electronics, and the J1939 interface adds engine data viewing on compatible systems for RPM, temperatures, alarms, and other engine parameters the network provides.

Installation and power

Plan for cable routing and connector bend room. The unit measures 38.3 cm wide and 19.8 cm high, and it calls for 8.6 cm of clearance in front for connections. Mount it where it stays dry and ventilated, away from heat sources and high-interference wiring runs, and keep wiring tidy so vibration does not work connectors loose over time.

Power is straightforward on both 12V and 24V boats thanks to the 10 to 32 Vdc input range. The unit turns on when power is applied, so many installs use a dedicated breaker or switch to control power at the panel. It is not powered through the NMEA 2000 network, so it must be connected to a proper vessel power feed even if it is already on a backbone.

Charts, sonar, and onboard use

The GPSMAP 9500 platform supports Garmin Navionics+ and Garmin Navionics Vision+ cartography, with chart access handled through an external card reader (not included). Sonar options are supported through compatible sonar black boxes and transducers, which lets you build the system around the style of fishing you do without forcing a single transducer choice.

This setup makes the most sense on boats where you want clean dash real estate and flexible screen layouts, such as sportfishers, center consoles with multi-display panels, and larger cruisers where networking, video inputs, and engine data all land in one place.
