  • The OS-3 is a plug and play interface that allows replacement of a General Motors GMLAN factory radio. It will maintain operation of the OnStar system.

  • OnStar active LED and Ignition on LED.
  • Provides +12v switched accessory output. No more searching for switched +12v in fuse box or kick panel.
  • Steering wheel radio controls can be retained to control the new radio by using the SWI - X, JACK, ECL2 or PS.
  • New radio will operate with the vehicle RAP (Retained Accessory Power) circuit. The radio stays on after the key is turned off and stays on for approximately 10 minutes or until the drivers door is opened.
  • The OS-3 does not retain the factory XM receiver. You will lose the XM option when the factory radio is replaced with an aftermarket radio.
  • If you are not retaining the OnStar system, use the C2R-GM29 instead of this OS-3 interface.
  • Built in Smart Mute Circuitry will play OnStar audio through the front speakers while muting the radio or turning the radio off if a mute input circuit is not present.
