Installation Overview

Unpack and inspect all components. Plan installation location considering visibility, accessibility, and cable routing.

Select mounting location: Ensure clear view, away from magnetic interference.
Prepare mounting surface: Clean, dry, and structurally sound.
Route cables: Plan paths avoiding sharp edges, heat sources, and moving parts.
Connect power: Ensure correct polarity (red to positive, black to negative).
Connect antenna: External GPS antenna for optimal reception.
Connect NMEA devices: For interfacing with autopilot, sounder, etc.

WARNING! Disconnect boat's battery before making electrical connections. Ensure all connections are waterproof.

Mounting the Unit

Choose appropriate mounting method based on your vessel's configuration.

Bracket Mount: Use provided swivel bracket for adjustable viewing.
Flush Mount: Cut opening per template for permanent installation.
RAM Mount: Compatible with aftermarket RAM mounting systems.

CAUTION! Use appropriate tools and fasteners for marine environment (stainless steel recommended). Do not overtighten.

Electrical Connections

Power Cable: Red (12-32 VDC positive), Black (Ground), Shield (Drain).
Fusing: Install 3A fuse as close to power source as possible.
Voltage Range: 10-32 VDC; ensure stable power supply.
Wire Gauge: Use minimum 16 AWG for runs under 20 feet.

Tip: Use dielectric grease on all connections to prevent corrosion.

Antenna and Sensor Connections

For optimal GPS performance, consider external antenna installation.

Mount external GPS antenna with clear sky view.
Connect to 5-pin circular connector on back of unit.
Route cable away from other electronics to reduce interference.
For NMEA 2000 networks, use appropriate backbone and drop cables.

Note: Internal antenna may suffice for open cockpit installations.

NMEA Interface Setup

Connect to marine networks for data sharing.

Connection	Purpose	Settings
NMEA 0183	Connect to autopilot, sounder, VHF	4800 baud, default sentences
NMEA 2000	Modern marine network	Plug-and-play with certified backbone
Audio Alerts	Connect to boat's audio system	Line-level output

Tip: Verify NMEA sentences needed by connected devices in their manuals.

Initial Configuration

First power-up and basic setup.

Apply power: Unit will enter startup sequence.
Accept disclaimer: Read and accept to proceed.
Set language: Select preferred interface language.
Configure units: Set nautical/statute miles, feet/fathoms, etc.
Calibrate compass: If connected to fluxgate compass.
Set time: Manual or GPS time synchronization.

CAUTION! Complete initial setup in protected waters, not while underway.

Display and Settings

Access menus via front panel buttons or optional remote.

Main Pages: Chart, Highway, Compass, Active Route, Data, Sonar (with compatible sounder).

Settings Menu: System (backlight, beeps, language), Navigation (routing preferences), Chart (detail levels, shading), Tracks & Waypoints, NMEA Setup, Alarms (anchor, arrival, etc.).

Display Adjustments: Color mode (day/night), contrast, backlight level, screen orientation.

Maintenance & Care

Regular maintenance ensures optimal performance.

Cleaning: Use soft, damp cloth with mild detergent. Never use solvents or abrasives.
Lens Protection: Apply anti-fog treatment if needed in humid environments.
Connections: Periodically check for corrosion, especially in saltwater environments.
Software Updates: Check Garmin website for latest firmware updates.

CAUTION! Never submerge unit beyond IPX7 rating. Do not disassemble unit.
