1. Introduction
The Axxess Integrate AXDIS-CL2 Data Interface is designed to facilitate the installation of an aftermarket radio in select GM vehicles manufactured between 2000 and 2013. This interface provides essential features such as accessory power (12-volt 10-amp), retention of Retained Accessory Power (RAP), OnStar, OEM Bluetooth, and Steering Wheel Control (SWC) functionality. It is compatible with both non-amplified and analog/digital amplified audio systems, ensuring seamless integration with your vehicle's existing electronics.

4. Setup and Installation
The AXDIS-CL2 is compatible with a wide range of GM vehicles from 2000 to 2013, including models from Buick, Cadillac, Chevrolet, GMC, Hummer, Isuzu, Oldsmobile, Pontiac, Saab, and Saturn. This interface is designed to simplify aftermarket radio installation by providing necessary data conversions.
4.1 Wiring Connections
Connect the vehicle-specific harness to the AXDIS-CL2 module. Then, connect the other end of the harness to your aftermarket radio's wiring harness, matching wire functions (e.g., power, ground, speaker outputs, accessory, illumination). Ensure all connections are soldered or crimped securely and insulated with electrical tape or heat shrink tubing.
- Accessory Power: The interface provides a 12-volt 10-amp accessory output.
- Retained Accessory Power (RAP): The interface retains the RAP feature, allowing the radio to operate for a short period after the ignition is turned off.
- OnStar/OEM Bluetooth: The interface retains the functionality of the factory OnStar and OEM Bluetooth systems.
- Chimes: Factory warning chimes are retained through the interface.

4.2 Steering Wheel Control (SWC) Programming
The AXDIS-CL2 automatically detects the vehicle and the aftermarket radio for most applications. After connecting all wires, turn on the ignition. The interface will typically auto-program the SWC functions. If SWC buttons do not function correctly, refer to the detailed programming instructions provided in the full product manual (not included in this summary) or visit the Axxess website for specific vehicle and radio programming steps.
5. Operating the Interface
Once installed and programmed, the AXDIS-CL2 operates transparently, allowing your aftermarket radio to function as intended while retaining key factory features. The Steering Wheel Controls will operate the corresponding functions on your aftermarket radio (e.g., volume up/down, track skip, mode). OnStar and OEM Bluetooth will continue to function through the vehicle's factory systems.
6. Maintenance
The AXDIS-CL2 Data Interface requires no regular maintenance. Ensure it is installed in a dry, secure location away from excessive heat or moisture. Do not attempt to open the module casing, as this may void the warranty and could damage the device.
7. Troubleshooting
If you encounter issues after installation, consider the following:
- No Power to Radio: Check all power and ground connections. Ensure the vehicle's battery is fully charged. Verify the accessory wire from the interface is connected to the radio's accessory input.
- Steering Wheel Controls Not Working: Confirm the SWC wire from the interface is correctly connected to the aftermarket radio's SWC input. Re-attempt the SWC programming sequence. Some aftermarket radios require specific settings for external SWC interfaces.
- No Sound: Check all speaker wire connections. Ensure the vehicle's amplifier (if present) is receiving power and a turn-on signal. Verify the radio's fader/balance settings.
- OnStar/Bluetooth Issues: Ensure the interface is correctly connected to the vehicle's data bus. If issues persist, consult the vehicle's factory service manual or an authorized technician.
