Features

Radio Replacement Interface: The CRUX CS-GM11C is a radio replacement interface for select GM LAN 11-bit vehicles. It facilitates the integration of an aftermarket radio and enables retention of factory features when replacing a factory installed radio in select GM vehicles. This interface is also pre-programmed for retention of steering wheel controls.

Note: This interface does not retain the vehicle's factory OnStar, if equipped.

Vehicle Compatibility: The CRUX CS-GM11C radio replacement interface works with the following GM LAN 11-bit vehicles.

Make Model Year
Chevrolet Cobalt 2005-2006
Malibu 2004-2007
Pontiac
G6 2005-2009

Note: If your 2009 Pontiac G6 has one volume knob in the center of the radio, please use the CRUX CS-GM11B interface (sold separately).

Amplified or Non-Amplified Systems: The CRUX CS-GM11C can be used in GM vehicles with or without a factory amplified system. Its compatible with Bose, non-Bose, and Y-91 audio systems. 

Warning Chimes & Parking Sensors: The Crux CS-GM11C 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. The Crux interface module will also retain your vehicle's front and rear parking sensors.

Steering Wheel Control Retention: The CRUX CS-GM11C also features a steering wheel control output for Pioneer, Sony, Alpine, Clarion, Kenwood, and JVC 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 Crux 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).

Note: There are two steering wheel control harnesses; you will only use one based on the brand of your aftermarket stereo. Both feature a 4-pin connector which plugs into the interface module. One of the SWC harnesses is equipped with a 3.5mm connector and one blue/yellow wire (for Alpine/Clarion/JVC/Kenwood), while the other is only equipped with a 3.5mm connector (for Pioneer/Sony).

Wiring Harness: The included wiring harness features a 24-pin connector which plugs into your vehicle's factory radio harness and a 16-pin & 8-pin connector which plug into the CS-GM11C interface module. The wiring harness also provides the following bare-wire leads which will need to be soldered or crimped to your aftermarket head unit's wiring harness -

Customer Q&A

1 question already asked

Q
I have a 2008 Pontiac G6 GT with the Monsoon audio system, and it has chimes, OnStar, RAP, and steering wheel audio controls; and I'd like to retain all four things. Is there any one adapter that will preserve all four with an aftermarket head unit?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
