GPSMAP® 1623 - 16" chartplotter screen

For flush-mount installation, use the mounting template provided with the product. If you must print a template, ensure it is printed at 100% scale and verify dimensions with a ruler.

The cut-out dimensions for the GPSMAP 1623 are 234 mm (9 3/16 in) in height by 375 mm (14 3/4 in) in width. It is recommended to cut along the inside of the template line.

For mounting holes, allow a pilot hole of 3.2 mm (1/8 in) for wood screws, or a 6 mm (1/4 in) hole for a mounting plate. If no mounting plate is used, it is possible to tap threads to M4.

Yes, to connect standard Ethernet devices, such as a network camera, network switch, or PoE injector, to a Garmin Marine Network, a Garmin Power over Ethernet (PoE) isolation coupler (part number 010-10580-10) is mandatory. Connecting a PoE device directly to a Garmin Marine Network chartplotter will damage the chartplotter and potentially the PoE device.

It is also recommended to use a shielded cable, such as a CAT 5e F/FTP, for better protection of your equipment.

The GPSMAP 1623 offers extended video integration capabilities, enabling superior monitoring of your boat. You can view video on all chartplotter screens on your boat or display multiple video streams on a single combined display.

It supports integration of:

Network cameras: using a Garmin PoE isolation coupler (010-10580-10).Composite video cameras: current GPSMAP chartplotters (excluding some older series) have built-in video encoder functionality that shares connected video via their composite video input across all chartplotter screens.Touch gestures can be used to control the camera from the chartplotter, such as pinching to zoom and swiping to pan and tilt the camera. You can also customize the chartplotter to store on-screen presets for each camera, including position and zoom data.

Yes, the GPSMAP 1623 is compatible with FLIR thermal cameras. FLIR marine cameras provide thermal imaging and can optionally offer low-light camera output.

When you connect a FLIR camera to your compatible chartplotter, the network automatically detects the camera and displays it in the source list without requiring pre-configuration before installation.

Note that FLIR MD series cameras provide only thermal views, while FLIR M series dual-payload cameras can switch between thermal and visible views.

When the GPSMAP 1623 is connected to the appropriate cameras and sensors, it supports several camera tracking features:

Compass Lock: to keep the camera fixed on a compass heading.Vessel Lock: to lock the camera at a fixed angle relative to the boat.Slew-to-cue: to track AIS targets, MARPA targets, or waypoints.To use these functions, you must connect a compatible marine camera with tracking capability (such as a newer-model FLIR IP video camera), a GPS antenna, and a heading sensor (ideally a 9-axis sensor for optimal performance) to the Garmin marine network or NMEA 2000. For AIS and MARPA tracking, a compatible AIS receiver and a compatible radar device are also required.

For optimal network performance, Garmin recommends streaming no more than five video sources simultaneously on the Garmin marine network.

The GPSMAP 1623 can be configured to display multiple videos at once on combined displays. However, on devices with multiple composite video inputs, only one video function within a combined display can use an integrated video input.

The Garmin GPSMAP 1623, as a non-aviation product, is warranted against defects in materials or workmanship for a period of one year from the date of purchase. During this period, Garmin will repair or replace, at its sole discretion, any defective component under normal use, free of charge to the customer for parts or labor. The customer is responsible for shipping costs.

Garmin’s limited warranty for the GPSMAP 1623 does not apply in the following situations:

Cosmetic damage such as scratches, dents, and gouges.Consumable parts, including batteries, unless the damage to the product is due to a defect in materials or workmanship.Damage caused by an accident, abuse, misuse, water, flood, fire, or other natural disasters or external causes.Damage caused by service performed by anyone other than an authorized Garmin service provider.Damage caused by modifying the product without Garmin’s written authorization.It is important to refer to the printed manual provided with the product for all detailed warranty conditions and exclusions.

For flush-mount installation of the GPSMAP 1623, the mounting template specifies a cutout of 375 mm (14 3/4 inches) wide by 234 mm (9 1/8 inches) high. It is essential to adhere to these dimensions for a proper fit.

Yes, the GPSMAP 1623 comes with its mounting template. It is strongly recommended to use the template provided in the product box rather than printing one yourself to ensure precise dimensions for cutting.

To connect standard Ethernet equipment to a Garmin marine network, use a shielded cable, such as a CAT 5e F/FTP. This type of cable provides the best protection for your equipment and ensures optimal network performance.

The GPSMAP 1623 is designed for extended video integration and is compatible with network cameras and composite video cameras. It supports integration of third-party cameras, including FLIR cameras from the M and MD series. FLIR IP cameras are automatically detected by the Garmin marine network without prior configuration.

Yes, a Garmin Power over Ethernet (PoE) isolation coupler (part number 010-10580-10) is required to connect any standard Ethernet device (such as a network camera, network switch, or PoE injector) to a Garmin marine network. Connecting a PoE device directly to a Garmin chartplotter will damage the chartplotter.

The GPSMAP 1623 offers extended video integration capabilities. It allows you to view video from network and composite cameras on all chartplotter displays onboard. You can also display multiple video streams simultaneously on a single combined screen. Current GPSMAP chartplotters feature an integrated video encoder to share video streams connected via their composite video input across the entire network.

To ensure optimal performance of the network, Garmin recommends not displaying more than five video sources simultaneously on the marine network.

You can control compatible cameras directly from the touchscreen of your GPSMAP 1623 chartplotter. This includes using touch gestures to zoom, pan, and tilt the camera. It is also possible to customize your chartplotter to store presets, such as camera position and zoom data, for each camera.

The Camera Tracking function allows the GPSMAP 1623 to automatically control the direction of certain cameras. It offers several modes:

Compass Lock: keeps the camera fixed on a heading.Vessel Lock: locks the camera at a fixed angle relative to your vessel.Slew-to-cue: allows tracking AIS targets, MARPA targets, or waypoints.

To use the camera tracking function, you must connect specific equipment to the Garmin marine or NMEA 2000 network:

A marine camera compatible with tracking (e.g., a newer FLIR IP video camera).A GPS antenna.A heading sensor (a 9-axis sensor is recommended for better performance).For AIS target tracking, a compatible AIS receiver is also required. For MARPA tracking, a compatible radar device is necessary.

On FLIR dual-payload camera models, the video output cables are usually labeled V/IR and IR-only:

The V/IR cable provides a video feed that can be switched between daytime and infrared video, offering greater flexibility.The IR-only cable provides infrared video only.The V/IR feed is recommended if you are connecting only one cable directly to a chartplotter, as it offers more display options.
