Metra Electronics AXDI-CL2

The Metra Axxess AXDI-CL2 is an automotive radio replacement data interface module designed specifically for select General Motors (GM) vehicles (spanning model years roughly 2000 to 2014) equipped with Class II data bus systems.

When replacing a factory radio in modern GM vehicles, standard wiring kits will not work properly because vital vehicle signals (like accessory power and warning chimes) are run through the car’s computer data network rather than standard dedicated wires. The AXDI-CL2 acts as a translator between the vehicle and your new aftermarket stereo.

Key Product Features

• Provides Accessory Power: Generates a stable 12-volt, 10-amp ignition/accessory power output (since modern GM cars do not feature a traditional ignition wire behind the radio).

• Retains R.A.P. (Retained Accessory Power): Keeps your radio and accessories powered on after turning off the ignition until a door is opened, mimicking factory behavior.

• Retains Factory Chimes: Features an onboard speaker interface to preserve vital audible warning chimes and safety indicators that are normally lost when removing the factory radio.

• Navigation Outputs: Provides necessary data outputs for aftermarket navigation receivers, including parking brake, reverse gear, and speed sense (VSS) signals.

• Maintains Balance & Fade: Preserves audio control adjustments across the cabin speakers.

• Steering Wheel Control Ready: Comes pre-wired with a dedicated harness plug to easily integrate an Axxess AXSWC steering wheel control interface module (sold separately) if you want to keep your steering wheel audio buttons.

• Micro-B USB Updatable: Allows firmware updates via a computer to ensure compatibility with future vehicle configurations or software patches.

Application & Compatibility Notes

• Vehicle Scope: Designed for select GM Class II data bus vehicles built between 2000 and 2014 (such as various Chevrolet, GMC, Buick, Cadillac, and Pontiac models).
