About the Axxess AX-GMCL2 Wiring Interface
Problem: Installing an aftermarket receiver in many GM vehicles means losing the chime that warns the door is open, along with audible safety warnings.
Solution: Metra's AX-GMLC2 interface lets you replace the factory receiver in these vehicles while keeping the door chime and all audible safety warnings as well as your Retained Accessory Power feature (R.A.P.). The interface provides 12-volt accessory power, and also supplies the illumination, parking brake, reverse, and speed sense outputs you'll need to install a navigation receiver. The package includes a pre-wired harness to connect Axxess' ASWC-1 adapter (sold separately) to retain your steering wheel audio controls.
Wire up the AX-GMLC2 to your aftermarket radio, mount the module in a location where the chime can be heard, and plug it into the existing factory plug. Get the great sound you want, and keep all important safety features intact. The AX-GMLC2 does not retain OnStar and is designed for non-amplified factory systems, systems with analog amplifiers, or systems in which the factory digital amp has been bypassed. Warranty: 1 year.

Factory Non-Amplified and Amplified System Compatible: The Metra AX-GMCL2 is designed for GM vehicles with factory non-amplified audio systems, factory analog amplified audio systems, or when bypassing the factory amplifier. The AX-GMCL2 will retain balance and fade control.
R.A.P. (Retained Accessory Power): The ignition power source of most GM vehicles keeps the radio on until one of the doors is opened. This feature is called the R.A.P. (retained accessory power). The Metra AX-GMCL2 is designed to retain this feature.
Retains Warning Chimes: The Metra AX-GMCL2 retains factory warning chimes through the use of an on-board speaker.
12V/10A Accessory Output: In many GM vehicles, there is no 12-volt accessory wire in the factory harness, which requires the installer to run an accessory wire to the fuse box or underneath the steering column when installing an aftermarket radio. The AX-GMCL2 is designed to provide a 12-volt/10-amp switched accessory output (red wire).
Navigation Outputs: The AX-GMCL2 provides navigation outputs (VSS, Parking Brake, and Reverse) to help ease the installation process of an aftermarket navigation stereo.
Optional Steering Wheel Control Adapter: The AX-GMCL2 allows you to retain your vehicle's steering wheel controls using Metra's ASWC-1 steering wheel control interface module (sold separately). Your aftermarket stereo most also support steering wheel controls.
