PAC C2R-CHY4 Radio Replacement Interface for Chrysler - Retains

In this review the PAC C2R-CHY4 is evaluated as a practical solution for owners who want to replace the factory radio in select Chrysler-family vehicles while keeping critical vehicle functions intact. The main reason to consider this interface is simple: it lets a new aftermarket stereo connect to the vehicle's wiring and retain factory systems such as amplified speakers, steering wheel controls, and warning chimes. For installers and DIYers who need a straightforward harness that preserves vehicle data and accessory outputs, this PAC interface is worth considering.

Key Features

• CAN Bus compatible: Allows the replacement radio to communicate with the vehicle's network so that essential signals are preserved and functions continue to operate.
• Amplifier support: Works with both amplified and non-amplified stock systems so the factory amp can be retained when installing a new head unit.
• Steering wheel control output: Provides a single wire output for an SWI-CAN steering wheel control module to keep steering wheel buttons functioning.
• Retains vehicle alerts: Keeps all warning chimes and alerts such as back-up chimes, low fuel, and door/hatch ajar tones after radio replacement.
• Multiple trigger outputs: Supplies RAP 12V accessory output plus VSS, illumination, parking brake and reverse trigger outputs needed by many aftermarket radios and modules.
• Includes SWI modules: Ships with SWI-CAN and SWI-CAN2 modules to retain data and steering wheel interface for 2005-11 Chrysler radios.

Who It's For

The PAC C2R-CHY4 is best for owners of select 2004 and newer Chrysler, Dodge, Jeep, Mitsubishi, and Volkswagen vehicles who want to install an aftermarket stereo without sacrificing factory features. It suits installers who need a reliable harness that preserves the factory amplifier, steering wheel controls, and vehicle chimes while generating the accessory and trigger outputs required by many head units.

It is less appropriate for vehicles outside the supported model years or for users who plan a full custom wiring overhaul where retaining factory data is not required. Also, buyers expecting an all-in-one amplified output converter should verify compatibility with their specific factory amplifier before purchase.
