Our take on the Scosche GM23SR Factory Integration Adapter

by John Pollard
Scosche

You want to install a new car stereo in your 2006-up GM vehicle, but you don't want to lose helpful factory functions. Thanks to this Scosche GM23SR adapter, you can upgrade to the higher sound quality of an aftermarket receiver while maintaining your factory-installed safety and warning features, along with your steering wheel audio controls. All harnesses are included, and this interface includes high- and low-level connections for your aftermarket stereo. Warranty: 60 days.

Important Note: This harness is not compatible with OnStar or "Premium" Bose" audio systems. Your new car stereo must be compatible with steering wheel control adapters. Please check "Details" for more information. See Details for a list of compatible car stereos.

Features

Compatibility: The Scosche GM23SRstereo replacement interface allows you to replace your factory OEM stereo in select 2006-2011 GM vehicles (GM LAN29-bit), while retaining all necessary safety and warning features as well as retaining your original steering wheel controls (if factory equipped). Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.

Note: Not compatible with OnStar or "Premium" Bose (y91/y92/z75) audio systems. Please check the service parts code sticker usually located in the glove box for "y91", "y92", "z75" equipment codes.

Safety & Warning Chimes: When replacing the factory radio in your GM vehicle, the GM23SRinterface will replace portions of your vehicle's audible Safety and Warning Chime systems. Without the S3-1, your vehicle will lose these functions when the factory radio is replaced.

ECM Compatible: In addition, the Scosche GM23SRwill send the proper data commands to your vehicle's ECM (Electronic Control Module) to indicate a "healthy" status for diagnostic purposes when your factory radio is replaced with an aftermarket head unit. Otherwise, your GM vehicle's ECM (Electronic Control Module) will store an error code if operated without the factory radio installed and you may experience difficulty in having the vehicle service at the dealership.

Steering Wheel Controls: The Scosche GM23SRstereo replacement interface includes a separate steering wheel control module, which allows you to keep your GM vehicle's factory steering wheel controls when replacing the factory radio with an aftermarket head unit from Alpine, Clarion, JVC Kenwood, Pioneer, or Sony that is OEM steering wheel control compatible. No additional interface or programming is necessary.

High-Level/Low-Level Connections: The included wiring harness (S3GMLAN) provides high-level and low-level connections for your aftermarket head unit. The harness comes equipped with four low-level (RCA) inputs for GM Bose systems. The four low-level (RCA) inputs can be cut off for high-level (speaker) connection for Non-Bose systems.

Does the job but the instructions and install are VERY POOR

Written By rswaz, Springdale, PA on Saturday, June 28, 2014
Crutchfield Customer Review (What's this?)
 
The good news is that the harness powers the head unit and the warning chime/steering wheel controls all work. In this regard, the Scosche works as advertised. The installation instructions are TERRIBLE. There was a small relay included that is not mentioned anywhere in the instructions and is needed to power the unit. It is not even shown in their poorly drawn pictures. Since these kits are used for many different cars, I did not want to assume that it was needed for mine so I ignored it just like the instructions. After de-installing the head unit twice to troubleshoot and check all power, wire splicing, voltage, etc. Finally someone from Crutchfield told me to plug the relay into the harness. I'm sorry, but the lack of clear instructions is inexcusable. Given the cost of this harness, they should spend a few bucks and re-write the instructions.
Pros:
Connections fit, warning chimes and steering wheel controls work.
Cons:
The install instructions are missing important information.

Great adapter

Written By MB, Dayton, Ohio on Saturday, February 08, 2014
Crutchfield Customer Review (What's this?)
 
I was concerned about using a adapter for the steering wheel controls because the factory controls were sluggish and my fear was that an adapter would be even slower. This is NOT the case. This adapter works faster, better that the factory controls. What a great surprise! The turn signal chime is louder than it used to be but this does not bother me, someone said it sounded like someone chopping wood- cracked me up but it kind of does. If you have your stereo up higher than 10 you won't even hear it. Because this adapter controls the turn signal chime it has a flasher harness along with two other harnesses so make sure you have a lot of room behind your stereo. This will be a problem for some vehicles, I have a 08 silverado and there is a lot of room back there. I used the extra connectors from crutch field and they worked great, easier than solder and more secure that wire nuts.
Pros:
I am thrilled
Cons:
Needs a lot of room behind the stereo

Decent

Written By Rob, TN on Friday, November 08, 2013
Crutchfield Customer Review (What's this?)
 
I paired this unit with an 07.5 Sierra (new body style no Bose) and a JVC 510HDT. The unit does retain many of th steering wheel controls. Unfortunately, the answer call button only acts as a mute now. If I use this feature, the radio stays muted until the head unit is reset. Odd, but as long as I don't use the call button works good enough for me.
Pros:
Retains many stock functions
Cons:
Call button spazzes out my head unit.

Scosche GM23SR Factory Integration Adapter

Written By Anonymous, Fresno, ca on Saturday, June 22, 2013
Crutchfield Customer Review (What's this?)
 
Wiring to stereo was easy and straight forward. Does as advertised, it retained all of the warning chimes as well as all of the steering wheel controls in my Traverse. Only issues I have are that the volume of the chimes are fairly low (which is fine except for when it comes to the parking assist); and the parking assist warning doesn't begin beeping until you are about a foot away from an object. With the factory radio it began warning you with a slow beep much earlier and got faster the closer you got to an object.
Pros:
Easy wiring. Retained steering wheel controls perfectly.
Cons:
Parking assist should begin beeping much sooner than it does.

I have a 2011 gmc Sierra non Bose crew cab . I replaced all the factory speakers with 6.5 infinitys . I installed a kenwood exelon head unit. this harness was very simple to install. I sat at the table and did all of the wiring then went out to the truck and plugged it in and everything worked out fine. It took me about a hour to a hour and a half.
Pros:
Very easy to install
Cons:
None

Everything worked as expected

Written By Anonymous, Columbia, TN on Thursday, November 29, 2012
Crutchfield Customer Review (What's this?)
 
This item did everything as expected and was not that hard to install. As others have reviewed, there is a significant amount of wiring to do, but there is no wiring harness that would make the wiring any easier. As far as the instructions provided, there is a list of the wire colors and corresponding functions, so figuring out how to wire to the head unit harness is fairly simple. I had no problem getting this wired and working.

After the install of this system, I would say everything seems to work great. The only issue i have is that my blinker now sounds like a small person chopping wood. I didn't ever used to have any sound or detect any sound from the blinker before this install.

Scosche GM23SR Factory Integration Adapter

Written By Kevin, Ashland, NE on Monday, November 19, 2012
Crutchfield Customer Review (What's this?)
 
Had a lot of issues getting this to work. First didn't have any power (turned out to be a blown fuse at no fault of the unit) but then had power 100%. In other words, wouldn't ever shut off. Re checked the wiring numerous times, spoke with Crutchfield tech support many times. They sent me an entirely new wire harness and integration adapter. Found the problem as soon as I pulled the new harness out of the package. The first harness/adapter was missing a module that was plugged in to the extra plug for other components. All I had to do was plug that into my existing harness and it worked fine.

The other problem is when I have my turn signal on you can hear it "chiming" in the dash. Not a deal breaker, but a little annoying.
Pros:
Steering wheel adapter works like it should
Cons:
Scosche left out a major item from the original harness sent. A lot of wiring to do. Had to cut the RCA plugs off and splice the speaker wires. Turn signal noise. Not that difficult, just really time consuming. Could use better wire diagrams.

Tough Job!

Written By Royce, Sardis,MS on Friday, October 26, 2012
 
I just finished installing this on my 07' GMC Serria and it does the job but,,,,it's hard to install, you can't just plug it up..I had to cut RCA plugs off and splice the speaker wires.. You must use a relay that plugs directly into the harness that tech support said should have been included but wasn't. Instructions were not clear enough to hook up, had to call tech support several times to get it right. If it weren't for them I'd still be scratching my head...
Pros:
It works like it should.
Cons:
Lots of wires to splice, difficult instructions or just not clear enough..

Wiring diagram wasn't good enough to make this work. Had to call Crutchfield tech rep and they quickly resolved the problem.
Pros:
Easy to install
Cons:
Info supplied with kit not sufficient to make it work in the car. Tech rep researched and found what modification I needed to make it work.
