Frequently Asked Questions - SWRGM-49N CRUX

What is the CRUX SWRGM-49N used for?

The SWRGM-49N is an interface module that allows installation of an aftermarket radio in select GM vehicles while retaining factory features like steering wheel controls, chimes, and backup camera.

Which vehicles are compatible with the SWRGM-49N?

It fits specific Buick, Chevrolet, and GMC models from 2010-2017. Refer to the vehicle applications list in the manual for exact models.

Does the SWRGM-49N retain OnStar?

No, the SWRGM-49N does not retain OnStar. For OnStar retention, use CRUX part SOOGM-19N instead.

How do I adjust the chime volume?

Use a small screwdriver to turn the potentiometer on the module. Clockwise increases volume, counter-clockwise decreases. It is set to halfway by default.

How do I configure the DIP switches for my radio?

Set DIP switches 1-3 according to the chart in the manual. For example, for Pioneer set all OFF; for Kenwood set all ON. The chart lists settings for most major brands.

Which SWC cable should I use?

Use Option A (Blue/Yellow wire) for Alpine, Clarion, JVC, and Kenwood radios. Use Option B (3.5mm plug) for Atoto, Boss, Pioneer, Sony, and most other brands. Cap unused wire/plug.

Will the module work with a Bose amplified system?

Yes, the SWRGM-49N supports Bose amplified, Premium Y-91, and non-amplified audio systems.

Can I retain the factory backup camera?

Yes, the module includes a camera retention harness that connects to the OEM camera and aftermarket radio's rear camera input.

What if my aftermarket radio has wires for SWC instead of a 3.5mm jack?

Cut off the 3.5mm plug on Option B cable and connect RED to SWC Key1, WHITE to SWC Key2, and SHIELD to SWC Ground. Some radios need only SWC1 and SWC2.

Do I need to program the steering wheel controls?

For some radios (e.g., Atoto, Blaupunkt), you may need to program the SWC buttons via the radio's settings. Refer to your radio's manual for instructions.
