CH1A-RSX

Interface for Chrysler/Dodge/Jeep Vehicles

Introduction and Features

The CH1A-RSX 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 amplier 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 CH1A-RSX 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 ash 4 times.

4. The LED will ash 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 amplier: Connect the aftermarket radio’s front and rear speaker wires to the vehicle connector. Vehicles with a factory amplier: The factory amplier 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 amplier’s fading is controlled by data communication from the factory radio. Neither the aftermarket radio, or the RP Advanced interface have the ability to control the amplier’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 ash 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 specic 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 ash off and on conrming that you have successfully skipped that function and are ready to proceed to

the next one.

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 ash 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 Verication

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 amplied Systems will not fade as neither the aftermarket

radio, or the RP Advanced interface have the ability to control the amplier’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 driver’s door is opened.

6. The LED and radio will turn off when RAP turns off or the driver’s 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 CH1A-RSX 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 CH1A-RSX 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

CH1A-RSX 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 CH1A-RSX can be updated with new rmware as it becomes available using the PAC-UP interface updater (sold separately). Please visit www.pac-audio.com/rmware for available updates.
