 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.

Absolute life saver!!!!!!

Pros: Saved a days worth of wireing to add a Parrot 9200 system installed using a factory radio

Works Great!

Crutchfield Customer Review (What's this?)

I have a '98 Chevy Pickup with an after-market stereo and I was still able to use this with a Parrot blue-tooth device, no problem. Once you see how simple this is to hook-up, you'll realize it's worth every penny.



Wiring harness for my 1990 Cadalliac Deville

Crutchfield Customer Review (What's this?)

The wiring harness that comes with the Parrott 3200LS does not work on my mint condition 1990 Caddy. I ordered the harness from Crutchfield which arrived promptly which I installed and was working perfectly in less than an hour. Thanks Crutchfield!!




Parrot 3200 with GM wiring harness

Written by: James from Southern California on August 31, 2007

2001 GMC Sonoma
Crutchfield Customer Review (What's this?)

I installed the Parrot 3200 with the GM wiring harness in my 2001 GMC Sonoma, a perfect fit, perfect install. It was far easier than installing the Parrot 3200 in my 1999 Olds Bravada using pigtail connectors. (I had to cut and solder about 30 wires.) Both units work great, paired with a Verizon Treo 700 and a Nokia 3102i. I would highly recommend the Parrot 3200 for simple, effective handsfree bluetooth cellphone use in any vehicle. Buy a connecting harness if possible. It greatly reduces the installation time and complexity.
