|
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 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 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 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 Advanced 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.
