Installation Instructions for Garmin GPSMAP 12X2 PLUS Chartplotter

Important Information from the Manual

This document provides installation instructions for the Garmin GPSMAP 12X2 PLUS chartplotter. Before beginning, ensure you have the necessary tools: a drill with appropriate bits, a #2 Phillips screwdriver, a jigsaw or rotary tool, file, sandpaper, and marine sealant. Always disconnect the vessel's power supply before starting installation to avoid personal injury or damage to the device.

Mounting Considerations

When selecting a mounting location, consider the following:

• The location should provide optimal viewing and easy access to interfaces.
• The surface must be strong enough to support the device and protect it from vibration or shock.
• Ensure there is room for cable routing and connection.
• The device should not be installed closer to a magnetic compass than the specified compass-safe distance (65 cm).
• The location should be at a vertical angle, not a flat horizontal surface.

Bail Mounting the Device

1. Use the bail mount bracket as a template to mark the location of the four pilot holes.
2. Drill the pilot holes using a bit appropriate for your mounting hardware.
3. Secure the bail mount bracket to the surface.
4. Install the bail mount knobs on the sides of the device.
5. Place the device in the bracket and tighten the knobs.

Flush Mounting the Device

1. Trim the included template and secure it to the mounting location.
2. Drill one or more holes inside the corners of the solid line on the template to prepare for cutting.
3. Use a jigsaw or rotary tool to cut along the inside line.
4. Test the fit of the device in the cutout and refine with a file or sandpaper if necessary.
5. If using a nut plate, drill the required holes and secure the nut plates to the back of the mounting surface.
6. Install the foam gasket on the back of the device.
7. Connect all necessary cables before placing the device into the cutout.
8. Apply marine sealant between the mounting surface and the device to prevent leakage.
9. Secure the device to the mounting surface using the appropriate machine screws.

Wiring and Connections

Power/NMEA 0183 Cable: The wiring harness connects the device to power, NMEA 0183 devices, and optional alarms. Do not remove the in-line fuse holder. Connect the red wire to the positive (+) battery terminal and the black wire to the negative (-) battery terminal.

Garmin Marine Network: Use a Garmin Marine Network cable for all connections. Do not use third-party CAT5 cables. If connecting third-party devices like a FLIR camera, a Garmin Marine Network PoE Isolation Coupler (010-10580-10) is required.

NMEA 2000: Connect the device to an existing NMEA 2000 network using the included cables. If no network exists, you can create a basic one using Garmin cables. Use a NMEA 2000 Power Isolator if the network manufacturer is unknown.

J1939 Engine Network: Use a Garmin GPSMAP J1939 accessory cable. The device can receive J1939 sentences but cannot transmit over this network.

Video Connections: The device supports HDMI Out for screen duplication and CVBS IN for composite video input. Use Garmin accessory cables to prevent corrosion.
