About the Crux CS-GM29 Wiring Interface
Install a new radio and keep your factory features

Install a new radio and keep your factory features
The Crux CS-GM29 interface allows you to install an aftermarket radio in select 2006-up General Motors vehicles while retaining your warning chimes. The interface works in GM vehicles with or without a factory amplifier. If you're installing a Alpine, Boss, Blaupunkt, Clarion, Dual, Jensen, JVC, Kenwood, Pioneer, Sony or Soundstream car stereo, you'll retain the use of your steering wheel audio controls.
If you're installing a car stereo with a video screen and a camera input, you'll retain the use of your vehicle's backup cam. The interface also offers the reverse, mute, and Vehicle Speed Sensor (V.S.S.) outputs that you'll need if you're installing a navigation receiver. The system also keeps the Retained Accessory Power feature and the factory subwoofer (if present). It includes the control module and vehicle and steering wheel control harnesses.
Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if the CS-GM29 is compatible with your vehicle. Warranty: 1 year.

- **Not compatible with Express & Savana vans that are powered by a diesel engine.
Amplified or Non-Amplified Systems: The CRUX CS-GM29 can be used in GM vehicles with or without a factory amplified system. It's compatible with Bose, non-Bose, and Y-91 audio systems.
+12V 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 CS-GM29 is designed to provide a 12V/3A switched accessory output (red wire).
Warning Chimes: The Crux CS-GM29 retains factory warning & safety chimes through the use of an on-board speaker. The volume of the chime speaker is adjustable through a potentiometer on the interface module.
Retained Accessory Power (R.A.P.): The ignition power source of most GM vehicles keeps the radio on until one of the doors is opened; this feature is lost when replacing the factory radio with an aftermarket head unit without the proper installation accessories. The CS-GM29 is designed to retain the R.A.P. feature and keep the radio powered after the key is off, until the driver door is opened or the OEM timer ends; whichever happens first.
Navigation Outputs: The CRUX CS-GM29 radio replacement interface module provides a VSS (vehicle speed sense) and a Reverse Gear output to make installing an aftermarket Navigation radio simpler and less time consuming.
Backup Camera Retention: The CS-GM29 allows you to retain your GM vehicle's backup camera through the included backup camera harness with male composite video connector. Your in-dash aftermarket stereo must have a composite video camera input and a built-in video monitor.
Steering Wheel Control Retention: The CRUX CS-GM29 also features a steering wheel control output for Pioneer, Sony, Alpine, Clarion, Kenwood, JVC, Jensen, Dual/Axxera, Boss and other aftermarket head units. The steering wheel control output consists of a right-angle 3.5mm connector and a light blue/yellow wire (use the connection that your aftermarket head unit is fitted with). The CS-GM29 interface module will work with any of the listed aftermarket head units, by setting its three dip-switches (see owner's manual for appropriate setting).

I purchased this kit to replace a prior kit that did not allow for steering wheel controls nor factory chimes. The installation was simple and completed the installation within an hour. Highly recommended if you want to keep your steering wheel controls.
