About the CRUX SOCGM-17 Wiring Interface
Installing an aftermarket receiver in many late model GM vehicles means losing the chime that warns the door is open, along with audible safety warnings. The Crux SOCGM-17 GM Class II Data Bus interface lets you replace the factory receiver in these vehicles and keep the door chime and all audible safety warnings.
Connect the SOCGM-17 to the wiring harness on your new car stereo, mount the module in a convenient location, and plug it into the existing factory plug. Get the great sound you want, and keep all important safety features intact. This interface does not work with GM's Premium Bose® systems or Onstar®, and it won't allow you to keep your factory steering wheel audio controls. It will work with the standard Bose system. Warranty: 1 year.
Important Note: If you do not use an interface like this when you replace your factory radio, you will disable the audible warning system in your vehicle. Crutchfield cannot provide a free wiring harness for your vehicle, and we strongly recommend that you use the recommended interface when replacing this vehicle's factory radio. Failure to do so may result in serious injury or death.
