Features

Overview: The PAC C2R-GM11 Radio Replacement Interface allows easy connection of an aftermarket stereo in select General Motors vehicles; please see "Outfit My Car" to confirm compatibility. This interface provides connections for the new radio's power, illumination, and speaker leads. With the C2R-GM11, the new radio will replicate all factory chimes and audible turn signals. It also provides a data bus generated 12 volt accessory output, so the factory RAP system remains intact (Retained Accessory Power, RAP, keeps the radio powered after the key is removed from the ignition until the driver's door is opened, or ten minutes passes, whichever comes first).

Steering Wheel Controls: If your vehicle has steering wheel controls (and the aftermarket radio is compatible) they can be integrated using the optional PAC SWI-RC steering wheel control interface (541SWIRC, sold separately).

Customer Q&A

Q
Crutchfield asked: Why did you buy this?
A
I had purchased another wiring harness from a large retailer that simply stated it would work for my year, make and model, It didn't. But with the Crutchfield compatability software and the added help from your tech support I'm 100% confident I chose the right one this time! [ Joseph  Apr 24, 2018 ]

Fits car [ Josh  Jul 24, 2017 ]

I bought this because, of the plugs would plug into my factory harness and would be able to keep my chimes and warning sounds. [ Christian  Jan 24, 2017 ]
A
again, recommended [ David  Oct 18, 2016 ]
A
This was automatically recommended based on my vehicle entered. This was very helpful because although I could have gotten the job done a little cheaper, the Crutchfield tech and I both agreed this was needed to retain my turn signal noise in my vehicle over the other brand. [ Jason  Jun 27, 2016 ]

Whenever possible, you still want all your cars features, that may have been controlled by your factory radio, to still work properly. [ Armand  Dec 18, 2015 ]

Q
If I have the Chevy HHR with pioneer headunit. Will this adapter work with a 3rd party headunit and still use the builtin pioneer power amp?

You will want to contact an Advisor by phone (1-800-324-9695) or online chat to discuss compatibility with your factory system. They will be able to pull up your vehicle and see if this will integrate. If it does not, then they will also be able to discuss other options with you.
