Our Product Research Team
At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere.
That's because we have our own in-house Product Research team — they open the box,
verify contents, check the owner's manual, and record dimensions, features and specs.
We stay on top of new products and technologies to help people make informed choices.
Compatibility: The Scosche S3-1 stereo 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 S3-1 interface 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 S3-1 will 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
Steering Wheel Controls: The Scosche S3-1 stereo 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.
