A flush-mount template and hardware can be used to mount the
device in your dashboard.
1
Trim the template and make sure it fits in the location where
you want to mount the device.
2
Secure the template to the selected mounting location.
3
3
Using a 9.5 mm (
/
in.) drill bit, drill one or more of the holes
8
inside the corners of the solid line on the template to prepare
the mounting surface for cutting.
4
Using a jigsaw or rotary cutting tool, cut the mounting surface
along the inside of the solid line indicated on the template.
5
Place the device into the cutout to test the fit.
6
If necessary, use a file and sandpaper to refine the size of
the hole.
7
NOTE: Not all devices have trim caps.
Using a pry tool such as a flat piece of plastic or a
screwdriver, carefully pry up the corners of the trim caps
and slide the pry tool to the center
8
Ensure the mounting holes on the device line up with the pilot
holes on the template.
9
If the mounting holes on the device do not line up, mark the
new pilot-hole locations.
1
10
Using a 3.2 mm (
/
in.) drill bit, drill the pilot holes.
8
11
Remove the template from the mounting surface.
12
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 weather caps.
13
Install 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.
14
Place the device into the cradle.
15
Securely connect each cable to a port on the cradle.
16
Place the locking bracket over the cables.
17
Place the device into the cutout.
18
Secure the device to the mounting surface using the included
screws.
19
Install the trim caps by snapping them in place around the
edges of the device.
2

Wiring Harness
• The wiring harness connects the device to power and NMEA
0183 devices.
• The device has one internal NMEA 0183 port that is used to
connect to NMEA 0183 compliant devices.
• If it is necessary to extend the power and ground wires, you
2
must use .82 mm
(18 AWG) or larger wire.
• If it is necessary to extend the NMEA 0183 or alarm wires,
2
you must use .33 mm

Connecting the Wiring Harness to Power
1
Route the wiring harness to the power source and to the
device.
2
Connect the red wire to the positive (+) battery terminal, and
connect the black wire to the negative (-) battery terminal.
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.
