Radio Replacement Interface
with Nav Outputs for all Chrysler
Dodge / Jeep CANbus Vehicles With
or Without Premium Audio Systems
C2R-CHY4
1. 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.
2. Vehicles without a factory amplier: Connect the aftermarket radio’s front and
rear speaker wires to the 22 pin plug.
3. Vehicles with a factory amplier: The factory amplier only accepts two audio
channels (left and right). The amplier’s fading is controlled by data communication
from the factory radio. The aftermarket radio does not have the ability to control the
amplier’s fader. Connect the front outputs of the aftermarket radio to the rear inputs of the 22 pin radio connector. This will
allow navigation voice prompts and Bluetooth calls to be heard. The rear speaker outputs of the aftermarket radio are not used.
4. The accessory output wire is located on the 11 pin CAN INTERFACE harness - connect this wire to the radio’s accessory wire. The
accessory wire supplies +12v, 1 amp max when key is in the accessory or ignition position (g. 1: If more current is needed).
5. 11 pin plug (to CAN INTERFACE):
Blue/White - Connect this wire to the radio’s amplifier remote output. Connect this wire with or without OEM amp 1.
present! This connection is VERY IMPORTANT! Some of the C2R-CHY4
features will not function if this wire is not connetced!
White/Green - SWC output.2.
Green - Connect this wire to the radio’s reverse input wire only.3.
Orange/White - Connect this wire to the radio’s Illumination input wire only.4.
Violet/White - Connect this wire to the radio’s VSS input wire only.5.
Red/White - Connect this wire to the radio’s parking brake input wire only.6.
Note: Do not connect these wires to any circuit other than the radio’s wire harness.
6. 11 pin plug (to SWC INTERFACE):
This is a quick connection to a radio specic SWC interface. No additional
connections are necessary other than radio control connections. Plug the radio
specic SWC interface in to this connector and program the radio specic SWC
interface for version 2. Do not cut the loops. Refer to the SWC interface instruction manual for the radio specic control function
programming order.
7. Refer to the aftermarket radio’s instruction manual for testing VSS, Reverse, Parking Brake and Illumination outputs. For the most
current and Up-to-Date application guide please visit www.pac-audio.com
