Garmin GPSMAP 8400/8600 MFD, NMEA 2000, Garmin Marine Network

Overview

The Garmin GPSMAP 84xx/86xx series is a touchscreen multifunction display and chartplotter family with 10", 12", 16", and 17" Full HD screens, sold in packages that can include built-in sonar and either a Worldwide basemap or Garmin Navionics+ charts. It brings charting, navigation, and system control onto one helm display, with a screen that stays readable in bright sun and when you are wearing polarized sunglasses.

For system builds, it connects over NMEA 2000 and the Garmin Marine Network so you can share data and accessories across displays. Wireless connectivity includes Wi-Fi, Bluetooth, and ANT, which helps when you want app-based management and compatible wireless accessories in the cockpit.

All models use a housing built from die-cast aluminum and polycarbonate plastic and carry an IEC 60529 IPX7 water rating for incidental exposure up to 1 m for up to 30 minutes. Power input and fusing depend on display size, with support that fits common 12 V and 24 V onboard systems when wired and protected correctly.

Key features

• Full HD IPS touchscreen display in 10", 12", 16", or 17" sizes depending on configuration
• IEC 60529 IPX7 water rating for incidental exposure up to 1 m for up to 30 minutes
• Die-cast aluminum and polycarbonate plastic housing for helm environments with vibration and salt air
• Power input supports typical 12 V and 24 V systems: 10 to 32 VDC on 10"/12"/16" models and 10 to 35 VDC on 17" models
• Networking support for NMEA 2000 and the Garmin Marine Network to share data and accessories between stations
• Wi-Fi, Bluetooth, and ANT wireless connectivity, including ActiveCaptain app support
• SmartMode station controls for quick recall of saved helm layouts
• SailAssist sailing tools available for sailing data pages and race guidance
• On Sonar Yes configurations, built-in sonar support for CHIRP traditional plus ClearVü and SideVü scanning sonar with a compatible transducer
• Chart bundle varies by package: Worldwide basemap or Garmin Navionics+

Variants

This product family is offered across multiple screen sizes and bundle options. The configurations vary by display size (10", 12", 16", or 17"), the included charts and maps (Worldwide basemap or Garmin Navionics+), and whether the package includes built-in sonar (Sonar Yes) or a chartplotter-only setup (Sonar No).

When comparing options, treat Sonar Yes as the chartplotter/sonar combination packages and Sonar No as the display-only chartplotter packages. Chart content is also tied to the bundle, so the included cartography depends on whether the configuration is listed with Worldwide basemap or Garmin Navionics+.

Installation and helm fit

These displays can be mounted flush in a dash cutout or flat mounted so multiple screens can sit edge-to-edge for a glass-helm style panel. For 10", 12", and 16" units, plan about 11.1 cm (4 3/8 in.) of clearance behind the panel for connectors and cable routing.

If you prefer a bracket mount, the 10" and 12" models include the bail-mount bracket and hardware, while the 16" bail mount uses an accessory bracket. Before you seal and fasten the unit, confirm cable routing, strain relief, and access to the back of the display for service and any card access your setup requires.

Electrical and environmental notes

Operating temperature range is -15°C to 55°C (5°F to 131°F). For overcurrent protection, the 10"/12"/16" models specify a 10 A, 125 V fast-acting fuse, while the 17" models specify a 15 A fuse.

Power input depends on size: 10"/12"/16" models accept 10 to 32 VDC, and 17" models accept 10 to 35 VDC. That range supports both 12 V and 24 V systems, but the wiring gauge and fuse selection should match the model and your run length.

Networking and system integration

NMEA 2000 support allows the display to sit on a backbone with engine data, sensors, and marine instruments, while the Garmin Marine Network supports sharing and integration across multiple displays and network accessories. SmartMode layouts help keep common helm views one tap away when switching between tasks on the water.

Wi-Fi supports pairing with the ActiveCaptain app for functions such as software management and smart notifications, and OneHelm integration support allows compatible third-party systems to be controlled from the screen.

Sonar and transducer pairing

Configurations marked with Sonar Yes include built-in sonar capability. They support traditional CHIRP sonar and scanning views such as ClearVü and SideVü, with results that depend on choosing a compatible transducer matched to your hull and fishing style.

Configurations marked with Sonar No are chartplotter-only packages, which can make sense when sonar is already handled elsewhere in the system or when you prefer to add it separately.

Charts and day-to-day navigation

Some packages include the Worldwide basemap for general navigation, while others include Garmin Navionics+ chart content. Keeping the same chart bundle across stations can simplify route sharing and make it easier to keep everyone on the same page when running inshore channels or planning an offshore track.

Who it fits

This family is a good match for helms that want a bright touch display with room to expand into a networked system with radar, autopilot, and instruments. Anglers who want sonar on the main screen will typically use the Sonar Yes configurations, paired with a compatible transducer that matches the boat and how it is fished.

Many products sold by Apollo Lighting include a manufacturer's warranty covering defects in materials or workmanship. Warranty terms vary by brand, product category, and model, so eligibility, coverage duration, exclusions, and available remedies are determined by the applicable manufacturer. We recommend reviewing the warranty information provided with your product before installation or use, especially for marine electronics, navigation equipment, lighting, electrical systems, pumps, safety equipment, and other specialized marine products.

If you need warranty service, the claim must follow the process established by the manufacturer, authorized service center, or designated warranty provider. You may be asked for proof of purchase, a serial number, product registration, photos, maintenance or installation records, or other documentation. Apollo Lighting does not determine or modify a manufacturer's warranty coverage or final claim decision, but we are happy to help provide purchase information and direct you to the appropriate manufacturer or warranty resource.

Keep your receipt, product documentation, serial number information, and original packaging when practical. Damage caused by normal wear, misuse, improper installation, insufficient maintenance, corrosion, impact, unauthorized modifications, electrical issues, or operation outside the manufacturer's specifications may not be covered. Warranty claims are separate from standard returns, so a product that has been installed, used, or exposed to marine conditions may no longer qualify for return while still remaining eligible for evaluation under the manufacturer's applicable warranty.
