Description
PAC RP4-CH21 RadioPRO4
RP4-CH21 is for supported Chrysler-family vehicles where removing the factory radio would otherwise take factory controls and data-driven functions with it. PAC’s RadioPRO4 interface handles the vehicle data needed for the aftermarket-radio installation and retains supported steering-wheel controls and factory amplification.
The important buying decision is the exact vehicle/radio architecture. RP4-CH21 is not interchangeable with CH1A-RSX or newer generation-specific interfaces just because the vehicle is Chrysler, Dodge, Jeep or RAM.
Where It Fits
Use RP4-CH21 only when the exact vehicle, factory radio and audio architecture support this interface. Supported applications can retain steering-wheel controls, factory amplification, backup camera and data-driven vehicle functions, with application-specific limitations.
Manufacturer Specifications
- Manufacturer: PAC
- Model: RP4-CH21
- Product family: RadioPRO4
- Type: Chrysler-family CAN-bus radio replacement interface
- Supported retention: Application-dependent steering-wheel controls, factory amplifier, backup camera and vehicle data functions

Important: premium amplified systems can have functional limitations such as loss of aftermarket-radio fader control. Exact factory radio/audio package and required companion adapters must match the installation.
Where this fits in the build
The source unit has to fit more than the dash opening. Steering-wheel controls, factory cameras, amplified audio, chimes, USB, vehicle settings and data integration can change the correct installation path.
