PAC C2R-GM11b GM Radio Replacement Interface for GMLAN 11-bit Vehicles Owner's manual

  • Hello! I've reviewed the user manual for the PAC C2R-GM11b Radio Replacement Interface. This device allows for aftermarket radio installation in GMLAN 11-bit vehicles without OnStar or when OnStar is not wanted. It replicates factory warning chimes, provides turn signal indicators, and retained accessory power. I'm ready to answer any questions you have about the C2R-GM11b, including its installation, features, and compatibility.
  • What is the purpose of the C2R-GM11b interface?
    What does the interface replicate?
    What is the accessory output voltage and its function?
    Does the interface work with amplified audio systems?
