Metra Electronics AXDI-GMLN11

The Metra Axxess AXDI-GMLN11 (often typed as METAXDI-GMLN11) is an automotive radio replacement data interface module designed specifically for select General Motors (GM) vehicles built between 2006 and 2012.

When upgrading the factory head unit in these modern GM data-bus-controlled vehicles, a standard wiring harness will not supply necessary ignition power or keep critical safety systems active. This interface acts as an intelligent translator between the car’s computer network and your new aftermarket stereo.

Key Product Features

• Provides Accessory Power: Generates a reliable 12-volt, 10-amp ignition/accessory power output, since factory GM harnesses run radio functions through the data bus rather than a traditional switched ignition wire.

• Retains R.A.P. (Retained Accessory Power): Keeps the radio and accessories powered on after turning off the ignition key until one of the vehicle’s doors is opened.

• Retains Factory Chimes: Preserves vital audible warning chimes and safety indicators using a built-in onboard speaker.

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

• Audio System Compatibility: Engineered to support both standard non-amplified systems and select factory-amplified audio layouts, preserving speaker balance and fade controls.

• Steering Wheel Control Ready: 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 long-term compatibility.
