Our take on the General Motors Bluetooth® Wiring Harness by Crutchfield's Erin Blanton
Add Bluetooth® to your vehicle
This harness works with a Parrot hands-free Bluetooth kit to connect your compatible phone to your car's factory stereo system. Find the correct harness for your vehicle, then pick one of these Parrot kits: Parrot MKi9200, Parrot MKi9100, Parrot CK3100, or Parrot CK3000. You're on your way to enjoying hands-free calling in your car.
Remove the plug from the back of your factory radio. The General Motors Bluetooth Wiring T-harness plugs into that factory plug, then provides a connection to your factory radio and the Bluetooth kit. Reinstall the factory radio and mount the Bluetooth kit, and you're ready to go. When your cell phone rings, your radio or CD player is muted automatically, and the sound from your phone comes through your front speakers. Warranty: 1 year.
Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if this model is compatible with your vehicle.
With this harness, I was able to quickly and easily add the Parrot Bluetooth kit to my truck's factory radio. This allows me to have hands-free calling while still having the look of my factory radio.

Why did you buy this?
This harness was suggested by Rex my Crutchfield advisor which was something I was unaware existed. This should make the system connect permanently and with the best results. Thanks again Rex. [ DEBRA Nov 27, 2016 ]
Because I couldn't find an aftermarket stereo with high quality output that was better than my stock Pontiac headunit. I also wanted to keep full functionality of my HUD and steering wheel controls. [ Joseph Feb 18, 2016 ]
