C2R-GM11b
GM Radio Replacement
Interface for GMLAN 11-bit
Vehicles Without OnStar®
The C2R-GM11b allows aftermarket radio installation without retention of the factory radio. The interface replicates all factory
warning chimes, audible turn signal indicators and provides a data bus generated 12 volt accessory output that acts just as GM’s
R.A.P. (Retained Accessory Power) system did prior to radio removal. R.A.P. keeps the radio powered after the key is off, until the
driver door is opened or a 10 minute timer ends, whichever comes rst. The C2R-GM11b will work with or without factory ampli-
ed audio systems.
This Interface is Intended for use in Vehicles without OnStar® or when OnStar®
is not serviced or is unwanted. For OnStar® Retention use the OS-311b.
