and the mounting holes, and cutting the hole too large could

compromise the stability of the device after it is mounted.

The included template and hardware can be used to mount the

device in your dashboard.

If you want to mount the device using an alternative method

where it appears flat with the front of the dashboard, you must

purchase a flat-mount kit (sold separately, with professional

installation recommended) from your Garmin dealer.

Trim the template and make sure it fits in the location where

you want to mount the device.

Remove the protective liner from the back of the template

and adhere it to the location where you want to mount the

device.

Using a

in. (9.5 mm) drill bit, drill one or more of the holes

inside the corners of the solid line on the template to prepare

the mounting surface for cutting.

Using a jigsaw, cut the mounting surface along the inside of

the solid line indicated on the template.

Place the device in the cutout to test the fit.

If necessary, use a file and sandpaper to refine the size of

the cutout.

After the device fits correctly in the cutout, ensure the

mounting holes on the device line up with the pilot holes on

the template.

If the mounting holes on the device do not line up, mark the

new pilot-hole locations.

Using a

in. (3.2 mm) drill bit, drill the pilot holes.

Remove the template from the mounting surface.

If you will not have access to the back of the device after you

mount it, connect all necessary cables to the device before

placing it into the cutout.

NOTE: To prevent corrosion of the metal contacts, cover

unused connectors with the attached weather caps.

Install the rubber gasket

The pieces of the rubber gasket have adhesive on the back.

Make sure you remove the protective liner before installing

them on the device.

Place the device into the cutout.

Secure the device to the mounting surface using the included

screws

Install the decorative bezel by snapping it in place around the

edges of the device.

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.

on the back of the device.

• 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,

make sure to use wires from the same internal NMEA 0183

port.

• If it is necessary to extend the power and ground wires, use

16 AWG (1.31 mm²) wire.

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

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

addition, connecting the power cable without the appropriate

fuse in place will void the product warranty.

If it is necessary to extend the power and ground wires, use 18

AWG (0.82 mm²) wire.

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.

NMEA 0183 Connection Considerations

• The installation instructions provided with your NMEA 0183

compatible device should contain the information you need

to identify the transmitting (Tx) and receiving (Rx) A (+) and

B (-) wires.

• When connecting NMEA 0183 devices with two transmitting

and two receiving wires, it is not necessary for the NMEA

2000

bus and the NMEA 0183 device to connect to a

common ground.

• When connecting a NMEA 0183 device with only one

transmitting (Tx) wire or with only one receiving (Rx) wire,

the NMEA 2000 bus and the NMEA 0183 device must be

connected to a common ground.
