INSTALLATION OF LASER/RADAR ANTENNA
General Information
The laser/radar antenna is waterproof and designed to be
mounted at the front of your vehicle. Optimum mounting
location is near the license plate area. Since this module also
includes a Laser receiver, the front of this module needs to
“look” down the road with no obstructions. Radar signals will
pass through non-metallic materials such as fiberglass and
plastic, however, because of the laser receiver, there can be
no material blocking the receiver’s antenna window. If
obstruction cannot be avoided, consider the vertical mounting
option. Because the optimal location for mounting the antenna
varies by vehicle type, the hardware supplied is designed to
offer a wide variety of mounting options. We suggest choosing
the option that enables the antenna to be securely fastened and
provides the antenna window adequate forward visibility.
NOTE: The “antenna window” is the bubble area on the case
All references to antenna in this manual will be the bubble
area.
NOTE: Use of hardware that is not supplied or DRILLING
into the case will cause damage to the receiver and void the
warranty.
TIP: Use removable thread lock on the hardware to prevent any
bolts from backing out due to vibrations.
Antenna Mounting Brackets
There are two types of mounting brackets for the antenna:
Large L (1) and Small L (2). The Large L bracket fastens to 2 – 4
holes on the cover of the antenna. The Large L Bracket may be
fastened to the antenna in a variety of positions.
Do not drill into the receiver housing!

9
INSTALLATION OF LASER/RADAR ANTENNA
The layout of the holes on the large L bracket accommodates
multiple antenna mounting positions.
This arrangement provides flexibility for fastening the antenna/
bracket assembly to your vehicle in a manner that allows the
antenna window (ANTENNA) to have a forward looking view of
the road ahead. The Small L Brackets (2) may also be fastened to
the antenna in different positions as shown below:
The small L brackets may be fastened to any of the four holes on
the antenna.
Use one M3 x 20 bolt, washer and nut to fasten each Small L
Bracket to the antenna. Again, do not over tighten the screws.
In some situations it may be advantageous to use both the
Large L and Small L Brackets to install the antenna in a vehicle.
TIP: Use removable thread lock on the hardware to prevent
any bolts from backing out due to vibrations.

10
INSTALLATION OF LASER/RADAR ANTENNA
Large L and small L brackets maybe used in combination in a
variety of differnet ways.
The Small L Brackets are fastened to the Large L Bracket using the
#10-32 x 1/2" bolts, #10-32 nuts and lock washers.
To fasten the Large L or Small L Brackets to your vehicle, mark the
supporting structure through the appropriate holes in the brackets,
and then drill the holes in the supporting structure with a 13/64"
drill bit. Attach the bracket(s) to the supporting structure using two
bolts (#10-32 x 1-1/4") and corresponding nuts, flat washers, and
lock washers. Because rough road surfaces can cause excessive
vibration or bouncing, be certain to fasten the bracket(s) securely to
your vehicle.
Horizontal or Vertical Mounting Of Antenna
The antenna can be attached to the vehicle in a horizontal or
vertical position, or at any angle in between. Select the position
that allows you to fasten the antenna to your vehicle in the most
secure manner.
Horizontal Mounting - antenna window facing down the road
When mounting the antenna in a horizontal position (or on an
angle), remember to keep the ANTENNA window as close to
perpendicular as possible to the road surface

11
INSTALLATION OF LASER/RADAR ANTENNA
(ANTENNA window should not be angled up toward the sky, either
side or down toward the road surface).
Vertical Mounting (using the 45º Reflector) - antenna window
facing the ground, hood or either fender.
For vehicles that do not have sufficient clearance (about 5")
behind the grille to mount the antenna in a horizontal position,
the 45º. Reflector should be used.
The 45º Reflector is attached to the antenna with double sided
tape on the top of the antenna housing. Clean the surface with
isopropyl alcohol and let dry. Peel the protective backing of
one side of the double sided tape and place on the recessed
area on the top of the laser/radar antenna. Peel off the other
side of the double sided tape and then place the reflector onto
the antenna. Make sure that the reflector is
positioned properly.

12
INSTALLATION OF LASER/RADAR ANTENNA
Mount the antenna to the vehicle such that the ANTENNA
window is facing the road surface, sky, right or left of the vehicle,
and the reflector has an unobstructed view of the road ahead.
Mounted in this position, laser/radar signals are reflected into
the ANTENNA window.
Mounting the Temperature Probe
Find a location that is far enough away from the engine and
radiator heat but still in the airflow for the vehicle. Mounting
the Probe too close to these heat sources will give a higher
than expected result.
• Attach the mountable tie wrap (supplied) to the Temperature
Probe as shown.
• Mark location for Probe, and then drill a hole using a #32 drill
bit. Attach Probe with tie wrap in the correct orientation using
the 3.5 x 16 screw.
NOTE: Mount the Probe so that there is space between the
Probe and the mounting area. Do not mount Probe directly to
metal area. Mountable Tie Wrap

INSTALLATION OF LASER/RADAR ANTENNA
Antenna Cable to the Interface Box (iBox)
Once the antenna is installed, connect the antenna cable to the
quick disconnect interface cable. The antenna cable and the
interface cable have an arrow embossed in each plug. These
arrows must line up to properly to connect the cables together.
Run the cable along the edge of the engine compartment to
the firewall. Find a location in the firewall where other wires
(or the speedometer cable) enter the passenger compartment
and feed the phone jack connection through. Be careful not
to interfere with or disconnect other wires, cables, or
mechanical systems of your vehicle while routing the antenna
cable. If there is no easy way to route the cable through the
firewall, you can drill a 15/32” hole.
IMPORTANT: Check with the vehicle’s manufacturer to see if
there are any issues with drilling through the firewall.
CAUTION: When drilling or working around the vehicle’s
firewall, check the other side for any obstructions that might be
damaged.
The interface cable includes a rubber grommet to keep the
weather out of the vehicle. Also, keep the antenna cable away
from any areas in the engine compartment that may become hot.
Cable ties are provided to secure cables at various points in the
engine compartment and under the dash.

14
INSTALLATION OF INTERFACE BOX
Mounting the Interface Box (iBox)
The iBox provides a central location for the connection of all
available modules.
Installation steps:
• Locate a clear area under the dash that will accommodate the
cables and not interfere with the operation of the vehicle.
• Mount the iBox with screws (not supplied) or tie wraps to the
selected area.
• Secure the cables to the vehicle or an existing wire harness
with cable ties.
Mounting the Alert LED
The Alert LED not only provides additional visual indication of
alarms but when selected in option mode, doubles as a faux
security alarm LED.
Installation Steps:
• Select a location that is visible to the driver as well as from
outside the vehicle to give the illusion of a car alarm LED.
NOTE: Use a replaceable panel whenever possible; to restore
the vehicle to original conditions in case of sale or return to
lease company.
• Drill 1/4” hole in the desired location.
• Press holder into the hole.
• Slide the LED retainer ring over the LED. Insert the LED into
the holder from the back side of the mounting location. Slide
the retainer ring onto the holder until it latches into place.
• Plug the cable into the LED Port on the iBox.

INSTALLATION OF OPTIONAL LASER ANTENNA
Optional Laser Antenna
The LRM-360 provides both front and rear laser reception. Mount
the unit with the 3-lens array facing forward (down the road) and
the single lens facing behind. This approach offers the most
protection, since you will most often be traveling into a laser
signal, rather that away from it when laser speed enforcement
is encountered. For effective protection, make sure the laser
antenna has an unobstructed view forward and behind, and that
it is not placed behind the windshield’s metallic sun screens.
Installing the LRM-360
The laser antenna can be mounted to the front windshield
using the supplied windshield bracket.
Before using, attach the suction cup and rubber bumpers (2)
to the metal bracket. If necessary, you may bend the metal
bracket in order to position the laser antenna correctly (3-lens
array facing forward, single lens facing behind.)

Installing the Laser Antenna - Continued
Using Hook & Loop Fasteners, the laser antenna may also
be mounted to the back side of your rearview mirror. Be
careful not to block the rear facing lens when mounted in
this manner. Also, clean the appropriate surfaces with
isopropyl alcohol before adhering the adhesive side of the
fastener to those surfaces.

Fasteners.
Laser Antenna Cable Connection
Conceal the cable and plug the phone connector into one
of the AUX ports on the iBox.

17
INSTALLATION OF CONTROL PANEL
Installing the Control Panel
The control panel may be mounted using the through Dash
Bracket or supplied double sided tape. When choosing a
mounting location, consider the ease of viewing the display,
accessibility of controls (remember Mute Mode may be used
frequently), and concealment.
The Pro-3700 Control panel can also be mounted sideways
and even upside down!
Control Panel Mounted with Double Sided Tape
Fasteners can be used to mount the control panel to your
vehicle. Before adhering the adhesive side of the fastener to a
surface, clean that surface with isopropyl alcohol. Use of double
sided tape simplifies control panel installation.
Control Panel Mounted with Through Dash Bracket
Installation instructions are provided on the last page of this
manual. We recommend using a professional installer if you are
not familiar with customized dashboard installations.
Control Panel Cable Connection
Conceal the cable and plug the phone connector into the
DISP port on the iBox.

18
Voice Module Installation
The Voice Module provides audio for all aspects of modes, alerts
and GPS features.
To install:
• Make sure “Voice On” is enabled in Option Mode (default
setting). (See Option Mode in owner’s manual.)
• For maximum volume, find a convenient location close to
the driver’s ear, such as the trim panel between A & B pillars.
Attach speaker using the supplied clip.
• Run the cable from the location selected to the iBox, so that it
doesn’t interfere with normal driving operation.
• Plug the cable into the VOICE Port on the iBox. The volume is
controlled by the knob on Voice Module.
NOTE: This is the only audio option that can be plugged into
the Pro-3700. Any other device may damage the unit and void
the warranty.
Optional Rear Laser/Radar Module
For drivers interested in gaining increased detection from
behind, the Pro-3700 can be upgraded with a second
laser/radar antenna. This antenna is mounted in the back of
the vehicle facing rearward and can be purchased from many
Whistler retailers or directly from Whistler; ask for the Part
Number SWRA-37.
The Pro-3700 iBox is designed to operate with an additional
laser/radar receiver; the RADAR2 port is the input for the
optional laser/radar receiver. An asterisk is displayed next to
the Band ID when laser/radar signals are detected from this
module. Must turn RADAR2 on in Option Mode.

Mounting Guidelines
• Unit needs a clear view of the sky above.
• Some windshields have an Instaclear™ or Electriclear™ type
coating, that can affect GPS signals. Consult the vehicle’s
dealer or the owner’s manual supplied with the vehicle to
determine if the windshield has this coating.
To install:
• Select a location on the dash or center console so that it
doesn’t interfere with normal driving operation. (Remember
the unit needs to be able to “see” the sky).
• GPS module has a magnetic base to make installation
easy – simply place on a metal area.
Must turn GPS on in Option Mode.

POWER CONNECTION
Power Cable Connection
The iBox has the power cable attached to it. The ground wire
has a “U” type connector which should be fastened to a
metal surface that is grounded to the vehicle. Look for an
existing screw or bolt under the dash to use as a grounding
point. The power wire has a spade type connector that can be
connected to a switched or non-switched +12 volt DC circuit
in your vehicle’s fuse box. A switched circuit is one that has
power when your vehicle is on, but has no power when your
vehicle is off.
NOTE: To utilize the faux security LED option, the iBox should
be powered from a non-switched 12 volt source.
