Features

Overview: The PAC C2R-GM11b GMLAN Warning Chime and Radio Replacement Interface allows easy connection of an aftermarket stereo in select General Motors vehicles without Onstar; 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-GM11b, 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).

Compatibility: The C2R-GM11b Radio Replacement Interface for GMLAN 11-bit vehicles without Onstar is compatible with the following GM vehicles with or without a factory amplifier:

  • Pontiac: 2005-2009 G6
  • Chevrolet: 2005-2006 Cobalt, 2004-2008 Malibu (2008 Malibu Classic only), 2004-2007 Malibu Maxx

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 or the SWI-CP2 steering wheel control interface (sold separately).

Q
2006 Pontiac g6 sedan. Will this keep the alerts such as oil change, tire pressure, and windshield washer fluid levels?

A year and four months later and this head unit and interface are still sitting on my work bench. In other words, I have not installed these in the car yet. Someday - maybe this winter - I will finally get it installed into my 2011 Corvette with Bose. All of that aside, why don't you ask Kenwood - or Bill Crutchfield - this question instead of me? How am I to know if it will work for your car?

It doesn't have anything to do with those circuits. Thats in the body module.
