About the PAC OS2C-CTS Wiring Interface
PAC's OS-2C-CTS interface lets you replace the radio in 2003-up Cadillac CTS and SRX models while maintaining operation of the OnStar® system, warning chimes, and rear parking assist chimes. The OS-2C-CTS will work with standard GM or Bose amplified audio systems. Warranty: 1 year.
Note: This interface will not work with 2004-06 SRX models with Cadillac navigation radios. You'll lose the factory XM receiver and the ability to fade from front to rear speakers when you install an aftermarket stereo.

More details on the PAC OS2C-CTS Wiring Interface
Overview: The PAC OS-2C-CTS Radio Replacement Interface Module allows the installation of an aftermarket radio into select Cadillac CTS and SRX vehicles equipped with OnStar and a factory amplified audio system.
Note: You may use this interface even if the vehicle does not have OnStar, but does have the factory amplified audio system.
Vehicle Compatibility: The PAC OS-2C-CTS Radio Replacement Interface Module supports the following vehicles.
|SRX||2004-2006||Only vehicles without factory installed navigation radios|
Note: The OS-2C-CTS does not retain the factory XM receiver, you will lose this option when the factory radio is replaced with an aftermarket headunit. Due to the design of the factory amplified system, there is currently no way of fading from the front to rear with an aftermarket radio.
OnStar Compatible: The PAC interface module will maintain operation of the OnStar and factory amplified audio system. OnStar audio will play through the front speakers when active. Your vehicle's OnStar volume will not be adjustable (preset at medium level).
Warning Chimes: The PAC OS-2C-CTS also retains all warning chimes and vehicle rear parking assist chimes.
