The OS-2x is a plug and play interface that allows replacement of a General Motors Class II factory Stereo System while retaining the OnStar® sytem, Bose amp and speakers in select 2000-11 GM Vehicles.
The OS-2x has on board switching to allow audio from the OnStar® system to play through the two front speakers when OnStar® is active and will mute the aftermarket stereo. The CM1 chime module is not required when using the BOSE® amplifier. If not retaining the Bose amplifier, purchase the OS-2 and GMAHCM chime module instead. The OS-2x decodes chime signal commands on the Class-2 data-bus and supplies the appropriate warning tone (door ajar, seat belt, low oil pressure, hi-temp., low fuel, etc...) through the OE amplifier or external speaker and also retains vehicle parking assist chimes
» Safe & Sound Class II circuitry will not disable vehicle data bus even if interface loses power
» OnStar® active LED and Ignition on LED
» Provides +12v switched accessory output. No more searching for switched +12v in fuse box or kick panel
» Uses genuine Delphi chip for seamless integration
» Smart Sense Mute output to either mute the aftermarket radio or to turn it off when OnStar® is active
» OnStar® Volume control via factory steering wheel audio controls on selected vehicles*. [ steering wheel interface such as the SWI-RC (sold separately) is required]
» New radio will operate with the vehicle RAP (Retained Accessory Power) system. The radio stays on after the key is turned off.
» Decodes chime signal commands on the Class-2 data-bus and supplies the appropriate warning tone (door ajar, seat belt, low oil pressure, hi-temp., low fuel, etc....) through the OEM (factory) amplifier, external speaker, or through add-on chime module (GMAHCM) when not using the factory AMP.
» Does NOT retain the factory XM, Rear seat controls/headphones or rear seat DVD. You will lose these options when the factory radio is replaced with an aftermarket radio.
