DIP Switch Configuration
The PAC C4RAD features DIP switches for easy selection of pre-programmed button functions tailored to your specific car model and aftermarket radio.

Incorrect settings may result in improper functionality of your steering wheel controls.
Operating Instructions
Once correctly installed and configured, the PAC C4RAD module allows your factory steering wheel controls to operate your aftermarket radio. The functions typically retained include:
- Volume Up/Down: Adjust the audio level.
- Track Up/Down: Navigate through audio tracks or radio presets.
- Mode/Source: Switch between different audio sources (e.g., FM, AM, Bluetooth, USB).
- Mute: Silence the audio output.
- Answer/End Call: Manage phone calls if your aftermarket radio supports Bluetooth hands-free calling.
Specific button assignments may vary based on your vehicle and radio configuration. Consult your radio's manual for details on how it interacts with external steering wheel control interfaces.
Maintenance
The PAC C4RAD module is designed for durability and requires minimal maintenance. Ensure the module and its connections are kept dry and free from excessive dust or debris. Avoid exposing the module to extreme temperatures or direct moisture. No user-serviceable parts are inside the module.
Troubleshooting
| Issue | Possible Cause | Solution |
|---|---|---|
| Steering wheel controls do not function. | Incorrect DIP switch settings, loose wiring connections, incompatible radio/vehicle. | Verify DIP switch settings against the manufacturer's guide. Check all wiring connections for secure fitment. Ensure your aftermarket radio is compatible with steering wheel control interfaces. |
