RP4-CH11 Radio Replacement and Steering Wheel Control
Interface for Chrysler/Dodge/Jeep Vehicles
Introduction and Features
The RP4-CH11 interface allows the replacement of a factory radio in select Chrysler / Dodge / Jeep vehicles with MSCAN
or LSFT-CAN databus radios. Using this interface will retain factory features such as steering wheel controls (SWC)
vehicle entertainment system (VES) and the factory audio amplifier when the original radio is removed. Use of this
interface also allows you to program two radio functions to each SWC button by using short press long press dual
command functionality. The RP4-CH11 also provides data bus driven outputs such as retained accessory power (RAP),
vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.
Important Notes
1. These instructions only apply to revision 1.5.4.5 of the product. The revision info can be found on a small white sticker on the
interface and packaging.
2. The radio select rotary switch on the side of the interface must be adjusted to the proper radio setting before plugging the
interface into the vehicle (see next page for setting chart).
3. The interface comes pre-programmed for all of the vehicles factory SWC functions and does not require programming unless
you wish to re-assign the SWC functions or utilize short press long press dual command functionality. The SWC can always
be restored to default settings by pressing and releasing the program button on the side of the interface once and waiting 7
seconds for the LED to flash 4 times.
4. The LED will flash whenever a SWC button is pressed.

1. The radio select rotary switch on the side of the interface must be adjusted to the proper radio
setting before plugging the interface into the vehicle.
2. Only one of the two provided radio harnesses will be used. Remove the factory installed radio to determine the correct harness for your
particular vehicle.
3. Make all connections as described in the connection chart on page 1. Vehicles without a factory amplifier: Connect the aftermarket
radio’s front and rear speaker wires to the vehicle connector. Vehicles with a factory amplifier: The factory amplifier only accepts two
channels of audio input (left and right). Connect the front outputs of the aftermarket radio to the rear inputs of the vehicle connector. This
will allow navigation voice prompts and Bluetooth calls to be heard. The rear speaker outputs of the aftermarket radio are not used. Fading
is not supported in this application. The factory amplifier’s fading is controlled by data communication from the factory radio. Neither the
aftermarket radio or the RP interface have the ability to control the amplifier’s fader.
4. Connect the SWC wire according to the chart on page 1 (aftermarket radio MUST support a wired remote input)
5. If you wish to reassign functions to the SWC or utilize short press long press dual command functionality, follow the programming instructions
on the next page.
Default Steering Wheel Control Programming
IMPORTANT! The interface comes pre-programmed for all of the vehicles factory SWC functions and does not require programming
unless you wish to re-assign the SWC functions or utilize *short press long press dual command functionality. The SWC can
always be restored to default settings by pressing and releasing the program button on the side of the interface once and waiting
7 seconds for the LED to flash 4 times.

Short Press Long Press Dual Command Functionality
This feature allows you to assign two aftermarket radio functions to each of the vehicles SWC buttons. It can be used with as
many of the buttons as the user likes or none at all. When this functionality is implemented, quickly pressing and releasing a SWC
button will initiate the short press command, while pressing and holding a SWC button for longer than two seconds will initiate the
long press command. Please note that no long press commands are programmed by default. If you wish to assign dual command
functionality to the SWC please follow the programming steps on the next page.

Optional Steering Wheel Control Programming
If you wish to re-assign the SWC functions or utilize short press long press dual command functionality, the interface must be
programmed in the specific order shown on the chart below. If you come across a function in the chart that your steering wheel
does not have, or you do not want to program, press and release the program button on the side of the interface to skip that
function. The LED will flash off and on confirming that you have successfully skipped that function and are ready to proceed to
the next one.

1. Turn the key to the ignition position.
2. Press and release programming button on the side of the interface.
3. Within 7 seconds, press the button that is to be learned on the steering wheel. The LED will turn off when the button is pressed.
At this point you have two options:
A. For short press functionality: Release the button within 1.5 seconds. The LED will turn back on.
B. For long press functionality: Hold the button until the LED starts blinking. Release the button and the LED will
go back to solid.
4. If you need to program more buttons, repeat step 3 for each additional audio function on the steering wheel.
5. If you come across a function in the chart that your steering wheel does not have, or you do not want to program, press and
release the program button on the side of the interface to skip that function.
6. Once programming is completed, wait seven seconds. The LED will flash three times indicating end of programming.
7. Test the interface for proper functionality. Whenever a SWC is pressed the LED on the interface should blink. If any function
does not work, repeat the programming steps

Testing and Verification
1. Turn the ignition on. The LED on the interface will turn on and the +12v accessory wire will turn on.
2. Turn on the radio and check balance and fade. Note: Factory amplified Systems will not fade as neither the aftermarket
radio or the RP interface have the ability to control the amplifier’s fader.
3. Verify that the factory subwoofer (if present) is playing.
4. Verify that all SWC are functioning properly.
5. Turn off vehicle and remove key. RAP will be active and keep the radio on for 10 minutes or until the drivers door is opened.
6. The LED and radio will turn off when RAP turns off or the drivers door is opened.
PLEASE NOTE: If after installation, the text on the driver information center has changed to German, you will need to
visit a dealer and change the vehicle’s country code to U.S.A.
Vehicle Entertainment System (VES; If equipped)
1. Vehicles equipped with a DVD player built into the rear screen assembly: The RP4-CH11 will allow the VES DVD
player and rear screen to function as if the factory radio were present. A/V will be passed from the factory DVD player to
the rear screen and audio can be heard through the headphones. A/V cannot be passed from the factory DVD player to the
aftermarket head unit.
2. Vehicles equipped with a stand alone VES DVD Player: The RP4-CH11 will allow the VES DVD player and rear screen(s)
to function as if the factory radio were present. A/V will be passed from the factory DVD player to the rear screen(s) and audio
can be heard through the headphones. A/V can also be fed from the VES DVD player into an aftermarket head unit (head unit
must support A / V in) with the use of the CHYRVD (please check vehicle compatibility). It is VERY IMPORTANT that the
RP4-CH11 Blue/White remote input wire be connected for this feature to function properly!
3. Vehicles not equipped with a VES DVD Player (rear screen(s) only): In this application the CHYRVD (please check
vehicle compatibility) must be used in order to feed A/V into the factory screen(s) from an aftermarket head unit (head unit
must support A/V out). With the CHYRVD, A/V will be passed from the aftermarket head unit to the rear screen(s) and audio
can be heard through the headphones. If you wish to retain the Auxiliary inputs on the rear of the console you must disconnect
the factory wires from the auxiliary input then connect and run your own RCAs into the aftermarket head unit.
4. Vehicles equipped with a Reverse Camera: In order to retain the factory reverse camera the CHYRVD (please check
vehicle compatibility) must be used to feed video into the aftermarket head unit (head unit must support reverse camera
input).
Product Updates (Firmware)
The RP4-CH11 can be updated with new firmware as it becomes available using the PAC-UP interface updater (sold separately).
