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 Pioneer, Sony, Alpine, Clarion, Kenwood, JVC, or Blaupunkt 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.

Bought this to keep my steering wheel controls, chimes and onstar in my 2013 GMC Sierra 1500. Works perfect. I do wish my steering wheel controls were a bit crisper/quicker but that's a stretch for a complaint. Overall great prodcut.
Pros: Ease of use/setup.

Crux CS-GM29 Wiring Interface
Jason from AZ on 4/12/2018
2007 Chevrolet Avalanche
Great product and interfaces well with the vehicle, three things though: The illumination wire from the existing vehicle plug didn't have a wire in the new harness so that had to be bypassed. It has a wire that goes from the gmlan unit to the headunit, which outputs 12v fulltime regardless of illumination setting, but no wire that went to the existing factory harness (which does have an illumination wire), don't know if the illumination data is contained in the gmlan or not, I think it does but might be vehicle specific PID. The chime sound is a little on the weak side, took a little bit of adjustment in fitting in the dash to get the best sound out of it (good thing it's a compact unit), it would be nice to see a future integration similar to stock or a modular chime design. When using reverse parking system the beep is great, it's a little more rapid than the stock three speed beeps and gives more feedback as the speed of the beeps ramp up the closer you get to an object. It does occasionally lockup on that beeping sound though and the chime just stops, never a hard lockup and always resettable by taking it out of reverse and back in again. Overall a great product and very helpful in interfacing with my 07 Avalanche and Eonon ga2168. Used "western-union" splices with solder and heat-shrink when I installed the unit for very solid connections.
Pros: Almost everything needed to integrate with somewhat late model GM vehicles, worked well with my 07 Avalanche. Revived the Bose factory amplified system, great sound!
Cons: Chime is a bit weak and really tinny, not a deal breaker though, still works very well even with the reversing hiccup once in a while. Needs illumination wire to factory harness or bypass.

If you want an interface to keep your stearing wheel audio controls and your OnStar as well as wireless calling than this is for you and all for under $50. It's super easy to install and plug right in to your vehicles wiring harness. I absolutely love it and the module is so small it tucks right behind your chosen after market head until.

I spoke with the service at Crutchfield about which harness to get for my 2007 Silverado because I didn't need the back up camera or DVD wiring harnesses. They steered me to this one. There were right on the money. It installed without a hitch and does exactly what I wanted it to do. I saved money and got what I wanted. It's perfect!
Pros: Installs easily and does what it's meant to do.
Cons: None.

Must have.
Morganne from St Paul, MN on 4/20/2017
2008 Chevrolet Silverado
This made my install sooooo easy. The instructions are pretty cryptic when wiring the SWC wire but as long as you double check that it's the right wire using the radio's wiring manual it was easy enough to do. I just did it last so I didn't make a mistake I had to undo. I would 100% recommend this to everyone doing an aftermarket radio in a 2007.5+ Silverado. There is no lag in my SWC either I read that somewhere about this adapter. I think they did something wrong or it's the radio. One thing I did that was really stupid was put my on/off switches backwards. It took me an hour to realize it was that and not my wiring so just double check. I got too excited to finally plug it in and made a mistake there.
Pros: Ease of install Straughtforward
Cons: SWC instructions

This was a very easy installation. I have a 2007 Cadillac escalade with out the Bluetooth. After looking at all options I opted for replacing the original stereo with an aftermarket with Bluetooth. I had never installed a radio before. I watched an online video and decided to give it a try. The wiring interface was very easy to install and I was able to retain all the steering wheel controls from the OEM radio. The support team is very reliable, I'm very happy with the results.

Works like a champ! I have a 2007 Silverado with Steering Wheel Controls and OnStar. I wanted something to control the Steering Wheel but not OnStar since I don't pay for that service, and this does exactly that. Also, the voice looking button on the steering wheel activates Siri, so I can do voice commands like, Call John's Cell, Play Music, etc. while driving down the road.
Pros: Works as intended

Great wiring harness for GMC Sierra
Blake from Gainesville, FL on 11/23/2016
2008 GMC Sierra
I was deciding on which wiring harness to use to install my kenwood ddx9903s in my 2010 GMC Sierra, and I ultimately decided on this harness in order to keep the vehicle warnings and the factory steering wheel controls. Install was almost all color matching and it all fit the car perfectly without any issues and turned out working great. It was definitely worth it to get the instal gear from Crutchfield with the radio because of the discount! No complaints!
Pros: Easy instal, keeps audiable warnings, able to use factory steering wheel controls with the radio, simple plug and play with the factory harness

Otis from Dearborn, MI on 10/26/2016

The Crux CS-GM29 Wiring Interface hooked up like it said it would. But the front speakers would fad in and out so I had to go in and run the speaker wire straight to the back of the aftermarket radio. And the volume controls on the steering wheel ever worked with Crux. The chimes work and they are louder then the factors.
Pros: Easy to install.
Cons: will call for a replacement box.

It facilitates the integration of an aftermarket radio and enables retention of factory features when replacing a factory installed radio in select GM vehicles (with or without factory-installed amps). 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-GM29 radio replacement interface works with the following GM LAN 29-bit vehicles.

Notes:
- *Not compatible with 2012-up SUVs/Trucks that are equipped with factory-installed navigation radios.
- **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. Its 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 GS-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, and Blaupunkt 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).
Note: The steering wheel control harness features two 4-pin connectors, two 3.5mm connectors, and one blue/yellow wire. You will only plug in one of the 4-pin connectors to the interface module and one of the 3.5mm connectors or blue/yellow wire into your aftermarket head unit you are installing (refer to owner's manual for which connection to use).
GM LAN 29 Harness: The included GM LAN 29 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-GM29 interface module. The GM LAN 29 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:
Wire Color Function Black Chassis Ground Red +12 Volt Accessory Yellow +12 Volt Constant Orange Illumination Blue/White Amp Turn-On White Left Front Speaker + White/Black Left Front Speaker - Gray Right Front Speaker + Gray/Black Right Front Speaker - Green Left Rear Speaker + Green/Black Left Rear Speaker - Violet Right Rear Speaker + Violet/Black Right Rear Speaker - Red/White Reverse Gear Green/White VSS (Vehicle Speed Sense)
