Retained Factory Features: The CRUX ONST-11B retains important factory features such as OnStar with Bluetooth hands-free communication, factory amplifier, steering wheel controls, RAP, and warning chimes.

  • OnStar System: The ONST-11B will retain the factory OnStar system for emergency communication

Make sure you connect your radio via the appropriate SWC connector (either blue/yellow wire or 3.5mm jack) and set the dip-switching according to the installation instructions.
  • RAP & Warning Chimes: The CRUX ONST-11B allows you to retain all of your vehicle's factory warning chimes, including RAP, with adjustable volume.

Navigation Outputs: To make installation of aftermarket DVD, digital multimedia, and navigation receivers simple and less time consuming the CRUX ONST-11B contains Parking Brake, VSS (Vehicle Speed Sensor), and Reverse Gear outputs.
