If you will have access to the back of the device, apply

marine sealant around the cutout.

Place the device into the cutout.

Secure the device to the mounting surface using the included

M4 screws

Wipe away all excess marine sealant.

Install the decorative bezel by snapping it in place around the

edges of the device.

Cable and Connection Considerations

If your model has a DVI port, a blue rubber seal is included. This

seal must be installed between the DVI port and DVI cable

connector to avoid damage to the connectors.

• For easer cable routing, the Garmin Marine Network cables,

the power and NMEA

0183 cables, and the transducer cable

are packaged without the locking rings installed. You should

route the cables before you install the locking rings.

• After connecting a locking ring to a cable, make sure the ring

is securely connected and the o-ring is in place so the power

or data connection remains secure.

About the Wiring Harness

• The wiring harness connects the device to power, NMEA

0183 devices, and a lamp or a horn for visible or audible

alerts.

• The wiring harness is packaged without the locking ring

installed. You should route the cable before you install the

locking ring.

• After connecting a locking ring to the wiring harness, you

should make sure the ring is securely connected and the o-

ring is in place so the connection remains secure.

• The device has two internal NMEA 0183 ports that are used

to connect to NMEA 0183 compliant devices. When

connecting to a device for both transmitting and receiving,

you must make sure to use wires from the same internal

NMEA 0183 port.

• If it is necessary to extend the NMEA 0183 or alarm wires,

you must use 22 AWG (.33 mm²) wire.

Connecting the Wiring Harness to Power

When connecting the power cable, do not remove the in-line

fuse holder. To prevent the possibility of injury or product

damage caused by fire or overheating, the appropriate fuse

must be in place as indicated in the product specifications. In

NOTICE

WARNING

addition, connecting the power cable without the appropriate

fuse in place voids the product warranty.

Route the wiring harness to the power source and to the

device.

Connect the red wire to the positive (+) battery terminal, and

connect the black wire to the negative (-) battery terminal.

Install the locking ring and o-ring on the end of the wiring

harness.

Connect the wiring harness to the device by turning the

locking ring clockwise.

Power Cable Extensions

If necessary, the power cable can be extended using the

appropriate wire gauge for the length of the extension.

Additional Grounding Consideration

This consideration is applicable only to devices that have a

grounding screw. Not all models have a grounding screw.

This device should not need additional chassis grounding in

most installation situations. If you experience interference, the

grounding screw on the housing can be used to connect the

device to the water ground of the boat to help avoid the

interference.

Garmin Marine Network Considerations

This device can connect to additional Garmin Marine Network

devices to share data such as radar, sonar, and detailed

mapping. When connecting Garmin Marine Network devices to

this device, observe these considerations.

• A Garmin Marine Network cable must be used for all Garmin

Marine Network connections.
