This PAC OS2-GM32 interface allows you to connect your new radio to the existing wiring in your vehicle and keep your factory features working. You'll keep the features you've become accustomed to such as safety warning chimes, the Bose amplified audio system, Retained Accessory Power (RAP), and the OnStar® system. If you have a standard Bose system, you'll be able to fade from the front to rear speakers with your new car stereo; if you have the Premium Bose system, you'll lose that ability.
The steering wheel controls for OnStar will still work, but you'll need a steering wheel control adapter (sold separately) to connect your new stereo to the Cadillac's steering wheel controls. You'll also lose the factory XM receiver.
