About the Crux SOCGM-17C Wiring Interface

Add a new radio

Installing a new car stereo can often mean losing your GM vehicle's factory warning chimes. Crux's SOCGM-17C wiring interface solves this problem, allowing you to install a new receiver while retaining the safety chimes and your Retained Accessory Power feature. This interface does not retain OnStar® or steering wheel audio controls.

Q
I have a KD-X340BTS deck that is satellite ready. With this harness, will my xm still work?
[ Bill  Feb 12, 2019 ]

A
Sorry, no. It does not retain factory satellite radio. For additional assistance and personalized recommendations, feel free to contact us directly by phone or through our online chat service: https://www.crutchfield.com/support/ContactUs.aspx

Q
I have a satellite ready deck KD-X340BTS to install. Will xm still work if I use this adapter?
[ Bill  Feb 12, 2019 ]
1 answer
A
This is the wiring harness and chime I needed for my make/model of vehicle. These are vehicle specific. I believe you have a separate adapter for enabling the satellite radio, that may be universal but not sure. My stereo has a separate spot for plugging in a satellite radio adapter for reception. Hope that helps.
[ David  Feb 12, 2019 ]
Q
Is the chime sound heard through the speakers or through this unit?
[ Daniel  Aug 06, 2018 ]

[ David  Aug 07, 2018 ]
A
With this particular model, the chime sound is heard through the internal speaker on the unit, not through the car stereo speakers.
