A necessary addition for my stereo installation

John from Massapequa Park, NY on 6/25/2019

2006 Pontiac Solstice

Verified customer (What's this?)
Verified employee purchase (What's this?)

A necessary safety / convenience feature that I was totally unaware of until I was looking for a new head unit for my 2006 Solstice. This product also included retention for the steering wheel controls. Unfortunately my controls don't work and I'm pretty sure that it is a steering wheel issue since it is doing the exact same problem as before I replaced the head unit. This product also came with all of the harnesses necessary for a complete installation.

Pros: Easy integration in my stereo system Adjustable volume levels Steering wheel control retention included

Cons:

Crux CS-GM11B Wiring Interface

BK from Naples, FL on 6/13/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

Sent first one back after right channel would not fade. Of course Crutchfield was right on it and sent me a second one. Still have the same problem. Had to bypass the box to make the fader work. Also noticed a strange distortion when going through the box. All that being said, my steering wheel controls and my chimes work perfectly. The fellow I spoke with in tech-support was very helpful and hadn't heard of this problem. I've been around car audio for a long time and it's the first time I've run into something like this. I would love to give it more stars but as you can imagine I burned up a lot of brain cells and a lot of time fooling with this.

Pros: Great all in one solution.

Cons: Had to bypass box with the speaker wires.

Features

Radio Replacement Interface: The CRUX CS-GM11B 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-GM11B radio replacement interface works with the following GM LAN 11-bit vehicles.

Make Model Year
Chevrolet Cobalt 2007-2010
HHR 2006-2011
Malibu 2008-2012
Pontiac G5 2007-2010
G6 2009-2010
Solstice 2006-2010
Saturn Aura 2007-2010
Ion 2007
Sky 2007-2009

Note: If your 2009 Pontiac G6 has two knobs on the radio, please use the CRUX CS-GM11C interface (sold separately).

Amplified or Non-Amplified Systems: The CRUX CS-GM11B 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-GM11B 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-GM11B 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 14-pin & 16-pin connector which plug into your vehicle's factory radio harness and a 16-pin & 8-pin connector which plug into the CS-GM11B 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 -
