Introduction and Features

Important Notes

Wiring Connection Chart

The C2R-AUDI interface allows the replacement of a factory radio in select Audi vehicles with CANbus radios. The C2R-

AUDI also provides a secondary output for adding an optional PAC Steering Wheel Control (SWC) retention interface

(SWI-RC, SWI-CP2, SWI-X). The C2R-AUDI also provides data bus driven outputs such as retained accessory power

(RAP), vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.

1. A PAC steering wheel interface must be used in conjunction for SWC retention.

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. Vehicles without a factory amplier: Connect the aftermarket radio’s front and rear speaker wires to the 22-pin plug (dock-

n-lock connector) or 16-pin plug (ISO Connector).

4. Vehicles with a factory amplier: To determine whether the amplier needs RCA or speaker level input, check the OEM side

of the 22-pin or 16-pin connector (depending on which connector your vehicle has behind the radio) to see if the speaker wires

are populated. If so hook the front speaker outputs to the main connector and the rear RCA outputs to the 22-pin connector

(dock-n-lock connector) or 16 / 20-pin connector (ISO Connector). If there are no factory speaker wires located in the OEM

main connector then you will need to hook all 4 of the RCAs from the C2R-AUDI harness to the aftermarket radio’s RCA

outputs. The blue RCA has no function at this time (dock-n-lock connector only).

5. The Red accessory wire supplies +12v, 1 Amp max when key is in the accessory or ignition position (see g. 1: If more current

is needed).

Installation Steps

1. Remove the factory radio.

2. Make all connections between the aftermarket radio’s harness and the supplied vehicle harness, as described in the wiring

connections chart on page 1.

3. Be sure to connect the Blue / White wire even if the vehicle is not equipped with an amplier.

4. Connect the C2R-CHY4 harness to the vehicle’s harness.

5. If retaining SWC, then follow the steps in the next section “SWC Output Connector”

SWC Output Connector

1. The harness has a SWC output connector. For ease of installation,

all necessary connections for an SWI have been made for you. Both

loops should remain intact.

2. When using this SWC output connector with the SWI-RC, the SWC

interface must be programmed for version 2 (refer to SWC interface

programming instructions for exact programming sequence and

button assignment order).

3. When using this SWC output connector with an SWI-CP2, you can

either program the SWC interface with a PC, or set the DIP switches

according to the PC app.
