PAC Wiring Interface

PAC's OS-2C-CTSX interface lets you replace the radio in 2003-07 Cadillac CTS and SRX models while maintaining operation of the OnStar® system, warning chimes, and rear parking assist chimes. OS-2C-CTSX will work with standard GM or Bose amplified audio systems. This harness also plugs right into a PAC steering wheel control adapter (not included) so you can retain those convenient controls. Warranty: 1 year. Note: You'll lose the factory XM receiver and the ability to fade from front to rear speakers when you install an aftermarket stereo. This interface will not work with 2004-06 SRX models with Cadillac navigation radios.
