Introduction & Features
The OS-5 interface allows the replacement of a factory radio in select General Motors vehicles with 29-bit LAN radios.
Using this interface will retain factory features such as OnStar, warning chimes, Rear Seat Controls (RSC), factory XM
Radio and the BOSE amplifier when the original radio is removed. The OS-5 also provides data bus driven outputs such
as retained accessory power (RAP), vehicle speed sensor (VSS), illumination, reverse trigger and parking brake.
Important Notes
1. The OS-5 will retain the use of the factory XM receiver. Factory SWC or RSE controls must be present for use of this feature.
2. SWI interface must be used in conjunction for SWC retention.
3. RSC buttons that are identical to the SWC will mimic the SWC function for function.
