Installation Guide
Professional Installation Recommended
Installation Best Practices
It is recommended that you have a professional
install your new Radenso RC M. To properly install
this system requires extensive experience with
automotive electronics. If you are unfamiliar with
12v electronics, many authorized dealers can
install your Radenso RC M system for you.
Before beginning your installation, please review
these tips to ensure a trouble-free installation:
Attempting to install this product without
expertise in automotive electronics may cause
personal injury or damage do your vehicle.
1. Determine the best location for the front and
rear radar antenna. For the front antenna, the
best location is typically mounted horizontally in
the slat of the grill of the vehicle, or alternately
mounted behind a flat section of the plastic
bumper.
2. DO NOT mount a radar antenna behind metal performance will be seriously compromised.
WARNING
The mounting location of your radar antennas
and laser sensors is absolutely critical to
determining the ultimate performance of your
installation.
The best performance will always be given with
a direct line of sight and a clear view of the road.
Technically, radar waves can pass through certain
types of plastic, so it is acceptable in certain cases
to mount the radar antenna behind a bumper or
grill. However, maximum performance will always
be achieved with nothing physically blocking the
radar antenna.
Laser is different than radar - it MUST have a
clear line of sight. Since laser is light based,
system performance is heavily dependent on an
unobstructed view with level, square mounting.
Please see further details in the “AL Priority Best
Practices” section of the manual.
3. It is usually possible to find an accessible
interior entry point for the radar wiring in the
vehicle’s firewall. Look where the steering
column passes through the firewall for an unused
grommet or hole that might be convenient for
passing wiring through.
4. Rear entry points can be more challenging to
find, but include gaskets behind license plates,
backup cameras, and near tail light wiring gaskets.
5. In some rare cases, it may be that no easily
accessible interior entry points exist. In this
scenario, a hole will need to be drilled through
the firewall. If drilling a hole, please ensure that
the hole is grommeted afterwards with a soft
rubber grommet. This will prevent undue wear on
the wires.
6. Cables coming into the car from rear-mounted
antennas and sensors can usually be routed
through the trunk/hatch compartment and
concealed under trim panels.
Installation Guide
RC M CPU Installation Tips
1. Install the CPU under the dash using the
supplied zip ties or 3M Adhesive Tape
structure on the car. You can use self tapping
screws, or bolts with matching nuts.
NOTE: Do not mount the CPU inside the vehicle’s
engine compartment. It is not weather-sealed.
4. Route the cable from the antenna through a
safe location under the hood, and plug it into the
matching extension cord.
2. Plug in the power harness to the CPU (it is the
only wire with a plug that will physically fit), and
connect the black wire (-) to ground, and the
red wire to a switched 12-volt power supply. It
is highly recommended to wire the CPU to a 12v
power source that is turns on and off along with
the car’s ignition. Connecting directly to the
battery may drain the vehicle’s battery.
3. The cables for the front and rear radar
antennas, front and rear AL Priority sensors, GPS
antenna, RC M display, and AL Priority bridge box
all plug into the CPU.
4. It is recommended that after the interface
is installed and connected to power, all other
components are plugged in and tested for proper
operation before completing the installation.
Front Radar Receiver
1. Determine the best location for the front radar
antenna. Typically, the best location is behind a
flat portion of the plastic bumper. Alternately, the
antenna can be mounted behind the grill.
2. Using the included stainless steel bolts and
nuts, secure the antenna to the included black
metal mounting plate.
3. Using the included hardware, secure the
mounting plate/antenna assembly to a suitable
5. The next step is to pass the extension cord
through the firewall and into the cabin of the
vehicle. Locate a suitable entry point (usually
an unused grommet) and slide the cable gently
through the opening and into the interior.
6. Plug the cable into the RC M CPU.
AL Priority Bridge Box
1. Install the AL Priority Bridge Box under the
dash in a location that is close to the RC M CPU
using the supplied zip ties or 3M Adhesive Tape.
2. Plug in the included bridge cable to the AL
Priority Bridge Box, and then plug the other end
into the RC M CPU.
3. Plug the Bridge Box power harness into the
port marked “power,” and connect the black wire
to ground and the red wire to a 12v power source.
AL Priority Front Sensors
1. It is absolutely critical that the AL Priority
sensors be installed properly; since laser is line of
sight, if the sensors are obscured they will not be
able to defend against a laser encounter.
Installation Guide
2. The sensors MUST be installed IN FRONT of
any grilles, plastic, mesh, or other materials. They
must have a clear and unobstructed view of the
road.
3. Sensors must be installed level, perpendicular
to the road surface. They must be pointed
straight ahead and not toed in or out.
4. Three sensors are provided; for a proper
installation, visually section the front bumper of
the car into three equal sections. Each sensor
should be responsible for covering approximately
one third of the bumper area.
5. Sensors can be mounted to the vehicle in one
of two ways - with the included snap-in brackets,
or with 3M adhesive tape. If the area on your
bumper where you are mounting the AL Priority
sensors is already perfectly flat and level, you may
opt to use 3M tape to stick the sensors directly
to the bumper. If your mounting location is not
level, use the bendable metal brackets to attach
the AL Priority sensors.
6. Use the included bubble level to double-check
the quality of your installation. Ensure the AL
Priority sensors are level, pointed straight ahead,
and are not toed in or out.
GPS Antenna
1. The GPS antenna requires a clear view of the
sky to work ideally, but it can also be mounted
behind plastic such as the underside of the top
of the dashboard. Other locations include on top
of the dashboard with 3M tape, on the back of
the rear deck lid, or magnetically mounted on the
roof.
2. After mounting the GPS antenna, carefully
route the wire back to the RC M CPU and plug it
into the port labeled “GPS.”
Display and Control Module
1. The Display and Control Module on the RC M is
designed with two components - a flush-mountable
base that provides power, and a magnetically
removable display/button module that can function
as a kill switch for the entire system.
2. It is important to mount the display in a location
that is both easy to see and touch while driving.
7. Route the wires through the same firewall passthrough that you previously ran the RC M front
antenna wires through.
3. The power base of the display can be either flush
mounted or attached to a surface with 3M adhesive
tape. It is important that the base be mounted
securely so when the user removes the magnetic
display, the base station does not get removed as
well.
8. Plug the sensors into the AL Priority Bridge box.
The middle AL Priority sensor MUST be plugged
into the F2 port on the ALP Bridge Box, the left
and the right sensors can be plugged into the F1
and F3 ports.
4. If flush mounting the display, be sure to protect
the area being cut with masking tape, and to
provide provisions for the USB cord to pass through
the opening and into the area where the RC M CPU
is located.
Installation Guide
5. Plug the USB end of the display cable into the
base of the display module, and carefully route
the other end back to the RC M CPU. Plug the
cable into the port marked “Display.”
Rear Radar Antenna
1. Follow the same installation instructions as for
the front radar antenna, but with the rear antenna
oriented to point out the rear of the vehicle.
Rear AL Priority Laser Sensors
1. Follow the same installation instructions as for
the front AL Priority Sensors, but with the sensors
oriented to point out the rear of the vehicle.
2. As with the front sensors, they MUST be
installed on the exterior of the vehicle, level with
the ground, and pointed straight to the rear of the
vehicle - not toed in our out horizontally.
After installation is complete, please proceed to the next section to update the software on the RC M and
ALP.
YOU MUST UPDATE SOFTWARE BEFORE USE!
RC M Update Procedure
IMPORTANT
Before powering on your device for the first time,
we will be preparing to update the firmware
on the RC M CPU and the ALP CPU (if present).
Updating the firmware is mandatory before use.
The firmware update process is similar for both
control units - we will be downloading firmware
files from a website, placing them on a USB flash
drive, and then plugging them into the control
units. Once powered on, the control units will
recognize the firmware files are present and
automatically begin updating.
Updating the RC M Firmware
1. Take the included USB flash drive and plug it into
a computer. Either Mac or PC is fine.
2. Point your browser to www.radensoupdate.com
3. In the center of the page, you will see text that
says “Or click here for manual serial number input.”
Click on the text”here” to go to the serial number
entry page.
4. Enter the serial number of the RC M CPU into the
“serial number” box. The serial number is just the
last five digits of the sticker on the back of the CPU.
For example, if the sticker reads “RR007 63148” than
the correct numbers to enter are, “63148”
5. For the drop-down boxes that say “front radar”
and “rear radar” select HDM+ for the front, and do
the same for rear if a rear antenna is present.
6. Click “upload and verify” and a box will pop up
offering two download options - “Download all in
one ZIP archive,” or “Download files individually.”
7. Click on the blue download icon next to the
“Download all in one ZIP archive” text to download
your firmware update.
8. When the download is complete, unzip all files in
the archive to the USB Flash Drive.
9. Remove the flash drive from your computer and
plug it into the RC M CPU’s USB port.
10. Power on the RC M system while the USB flash
drive is still plugged in. The RC M will automatically
recognize the software update file and begin
the update process. You will see several status
messages on the screen as the unit cycles through
updating the various modules (display, front
antenna, rear antenna, etc). Once the firmware
update is complete, the unit will reboot.
11. Manually power the RC M off and back on.
Once the RC M boots back up, the update process is
complete.
ALP Update Procedure
Updating the RC M Firmware
1. Take the included USB flash drive and plug it
back into your computer. Delete any existing files
on it so you are starting with a blank flash drive.
2. Point your web browser to www.alpupdate.com
and click on “I agree” to accept the Terms of Use.
3. You will see the option “Configure” in large text
on the left side of the page. Click on the blue
“Enter” button to enter the configuration file setup.
4. Select “North America” under the region dropdown. This will take you to a page with several
options.
5. By default, the AL Priority system is shipped in
parking sensor only mode. If you wish to enable
laser defense, you must choose the “PDC & LID”
option.
6. Choosing “PDC & LID” will present several
more options below. Leave everything default
except for “LID” time. THIS MUST BE SET TO
“Unlimited”!
7. Click “Save & download” to download your
configuration file. Move this file to the USB flash
drive.
8. Point a new browser window back to www.
alpupdate.com. This time, click on the blue “Enter”
button under the “Firmware upgrade” text.
9. Enter the serial number of your ALP control unit
(found on a sticker on the back of the unit) enter
the prompt, and press “OK.”
10. You will be prompted to answer a simple math
problem as proof that you are human and not a bot.
Solve the problem and hit “Press to Download”
11. A firmware file will be downloaded to your
computer. Move this file onto the USB flash drive.
The flash drive should now have two files on it; the
config file as well as the firmware file.
12. Remove the flash drive from your computer
and plug it into the AL Priority CPU unit’s USB port.
Make sure the RC M and ALP are both powered off
when you plug it in.
13. Turn on the RC M system and wait several
seconds. The RC M will automatically recognize
that the ALP has the firmware update flash drive
plugged in, and the CPU will begin updating.
14. Once the ALP has finished updating, the RC M
display will give you a message indicating that the
process has finished.
15. Remove the flash drive from the ALP control
unit and manually power off the RC M system.
16. Power the RC M system back on and the process
is complete.
