Overview

Our take on the PAC C2R-CHY4 Wiring Interface

PAC's C2R-CHY4 radio replacement interface lets you replace the factory radio in select 2004-up Chrysler, Dodge, Jeep, Mitsubishi, and Volkswagen vehicles, without losing the accessory output and other signals. It also allows the new receiver to turn on the factory amplifier, if present.

PAC's C2R-CHY4 radio replacement interface lets you replace the factory radio in select 2004-up Chrysler, Dodge, Jeep, Mitsubishi, and Volkswagen vehicles, without losing the accessory output and other signals. It also allows the new receiver to turn on the factory amplifier, if present.

Another plus -— once you've connected the appropriate PAC steering wheel audio control adapter for your new car stereo, the C2R-CHY4 interface eliminates the need for the second PAC interface (SWI-CAN or SWI-CAN2) that's usually required for your vehicle, saving you some cash. Warranty: 1 year.

Features

Radio Replacement Interface: The PAC C2R-CHY4 allows you to replace the factory radio in select Chrysler, Dodge, and Jeep LSFT & MSFT CANbus vehicles with an upgraded aftermarket radio. Connectors are provided for either type, and the interface auto detects which CANbus system is connected. The C2R-CHY4 has been engineered to seamlessly interface with your automobile's computer data-bus system and provide necessary outputs for installation of an aftermarket navigation radio, while retaining operation of your vehicle's factory installed amplifier (if equipped). The C2R-CHY4 will even turn on the factory amplifier via CANbus information.

Optional SWC Interface: The C2R-CHY4 provides a direct connection for the optional PAC SWI-RC steering wheel control interface (541SWIRC, sold separately), so you can retain your vehicle's factory steering wheel controls.

Factory Amplifier Note: Vehicles with a factory amplifier will lose front-to-rear fading capability when the factory radio is replaced. The amplifier's fading is controlled by data communication from the factory radio. The aftermarket radio does not have the ability to control the amplifier's fader.

Compatible Vehicles: This interface is compatible with the following Dodge, Chrysler, Jeep, Mitsubishi, and Volkswagen vehicles.

I used this for a 2006 PT Cruiser, but the principle is the same. This part is required for all modern Chrysler aftermarket sound systems. Cars and trucks now use the CAN (controller area network) bus for electronic components. The wiring in a car is multiplexed. It is not only supplying power. The CAN bus is a protocol that communicates with part of OBD (on board diagnostics). If you attach electronic components without taking into account the communication protocol, faults are highly likely. Some sysytems may not operate to prevent damage. Using the interface ensures that the aftermarket sound system will be tolerated/isolated by the vehicle OBD monitors. In my car the dash would display the radio frequency, CD, etc. with the temp and compass reading when factory stereo was in place. With the aftermarket sound system, the display would read VES for vehicle entertainment system. The wiring interface makes the aftermarket behave in the mode of a DVD system and all other systems operate normally. [ JOHN  Dec 17, 2015 ]
Hi Tom by not using the PAC c2r-chy4 it will not effect any of your heater controls or cause the car to turn off it only allows for the stereo to intergrate a aftermarket head unit with the factory amp if the car does not have a amp there is no need to use it hope this helps.

Yes. This allows it to communicate to, and through your vehicle. [ CHARLES  Jun 30, 2015 ]
If the radio you purchased is not compatible with the vehicle system YES.. I purchased a diff radio for my 2010 Jeep ( after the original was stolen) and the Crutchfield tech said I would need the interface to use my amp system..Excellent advise.. It works great, never a problem.. I live in Guatemala and the installer here had NO problem with the installation and instructions..Worth the money.. Hope this helps.. [ THOMAS  Jun 29, 2015 ]
If your using a different deck yes if not all you would need is the rca jacks hooked up to your factory radio but I would get rid of the factory radio and put a different deck in it [ SHANE  Jun 29, 2015 ]
YOu need this for any aftermarket head unit. I was gonna wire mine without it. Not possible. Really screwed stuff up. I recommend getting it now. Crutchfield sells it cheaper than at a store. [ DEVYN  Jun 29, 2015 ]
