Bail Mounting the Device
NOTICE
If you are mounting the bracket on fiberglass with screws, it is
recommended to use a countersink bit to drill a clearance
counterbore through only the top gel-coat layer. This will help to
avoid any cracking in the gel-coat layer when the screws are
tightened.
Stainless-steel screws may bind when screwed into fiberglass
and overtightened. Garmin recommends applying an anti-seize
lubricant to the screws before installing them.
1Select the mounting hardware appropriate for your mounting
surface and for the bail-mount bracket.
2Using the bail-mount bracket as a template, mark the pilot
holes through the screw holes.
3Using a drill bit appropriate for the mounting hardware, drill
the four pilot holes.
4Using the selected mounting hardware, secure the bail-mount
bracket to the mounting surface.
5Install the bail-mount knobs À on the sides of the device.
6Place the device into the cradle Á.
7Place the cradle in the bail-mount bracket and tighten the
bail-mount knobs.
Flush Mounting the Device
NOTICE
Be careful when cutting the hole to flush mount the device.
There is only a small amount of clearance between the case and
the mounting holes, and cutting the hole too large could
compromise the stability of the device after it is mounted.
Using a metal pry tool such as a screwdriver can damage the
trim caps and the device. Use a plastic pry tool when possible.
You can mount the device in your dashboard using the flush-
mount template and appropriate hardware.
1Trim the template and make sure it fits in the location where
you want to mount the device.
2Secure the template to the mounting location.
3Using a 9.5 mm (3/8 in.) 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.
4Using a jigsaw or rotary cutting tool, cut the mounting surface
along the inside of the solid line indicated on the template.
5Place the device into the cutout to test the fit.
6If necessary, use a file and sandpaper to refine the size of
the hole.
7If your device has trim caps, use a pry tool, such as a flat
piece of plastic or a screwdriver, to carefully pry up the
corners of the trim caps À, slide the pry tool to the center Á,
and remove the trim caps.
8Ensure the mounting holes on the device line up with the pilot
holes on the template.
9If the mounting holes on the device do not line up with the
pilot holes on the template, mark the new pilot-hole locations
on your template.
10Using a 3.2 mm (1/8 in.) drill bit, drill the pilot holes.
11Remove the template from the mounting surface.
12If 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 weather caps.
13Install the rubber gasket pieces on the back of the device.
The pieces of the rubber gasket have adhesive on the back.
Make sure you remove the protective liner before installing
them on the device.
14Securely connect each cable to a port on the cradle.
15Place the device into the cutout.
16Secure the device to the mounting surface using the included
screws.
17Install the trim caps by snapping them in place around the
edges of the device.
Installing the Cables and Connectors
Wiring to Power
1Route the power cable from the swivel mount to the boat
battery or fuse block.
2

2If necessary, extend the wires using 0.82 mm2 (18 AWG) or
larger wire.
3Connect the red wire to the positive terminal on the battery or
fuse block, and connect the black wire to the negative
terminal.
Connecting the Device to a Transducer
Go to www.garmin.com or contact your local Garmin dealer to
determine the appropriate type of transducer for your needs.
1Follow the instructions provided with your transducer to
correctly install it on your boat.
2Route the transducer cable to the back of your device, away
from sources of electrical interference.
3Connect the transducer cable to the appropriate port on your
device.
Connecting the Cables to the Cradle
The connectors on the cables are keyed to fit only in the correct
ports on the device or cradle.
1Compare the divots À on each cable connector to the keying
on each port to determine which cable corresponds to each
port.
2Securely connect each cable to a port.
Installing the Device in the Cradle
If your device uses a cradle and you have connected the cables
to the cradle, you can quickly place the device in the cradle
without plugging in any cables.
1Place the base of the device in the bottom of the cradle.
2Tilt the device toward the cradle until it fastens in place.
There is an audible click when the device is secured in the
cradle.
Removing the Device from the Cradle
1Press the release lever À on the cradle until the device is
released.
2Tilt the device forward, and lift it out of the cradle.
NMEA 2000® Considerations
NOTICE
If you have an existing NMEA 2000 network on your boat, it
should already be connected to power. Do not connect the
NMEA 2000 power cable to an existing NMEA 2000 network,
because only one power source should be connected to a
NMEA 2000 network.
If you are installing a NMEA 2000 power cable, you must
connect it to the boat ignition switch or through another in-line
switch. NMEA 2000 devices will drain your battery if the NMEA
2000 power cable is connected to the battery directly.
NMEA 2000 compatible models can connect to a NMEA 2000
network on your boat to share data from NMEA 2000 compatible
devices such as sensors or a VHF radio. The necessary NMEA
2000 cables and connectors are sold separately.
If you are unfamiliar with NMEA 2000, you should read the
“NMEA 2000 Network Fundamentals” chapter of the Technical
Reference for NMEA 2000 Products. To download this
document, go to www.garmin.com and select Manuals on the
product page for your device.
The port labeled NMEA 2000 on the back of the device is used
to connect it to a standard NMEA 2000 network.
NOTE: Models that are not directly NMEA 2000 compatible
require the included 4-pin adapter cable to connect to the NMEA
2000 network.

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 the device is mounted in a location that prevents the
internal antenna from acquiring a satellite signal, you can
connect an external GPS19x antenna through a NMEA 0183
connection. For more information, see the GPS 19x NMEA
0183 Installation Instructions.
