Introduction & Features

Important Notes

Wiring Connection Chart

Illustration / Schematic

The OS2-GM32X interface allows the replacement of a factory radio in select General Motors vehicles with Class II radios. Using

this interface will retain factory features such as warning chimes and BOSE® amplier (Standard or Premium) when the original

radio is removed. The OS2-GM32X provides Data-Bus driven outputs such as retained accessory power (RAP), vehicle speed

signal (VSS), illumination, reverse trigger and parking brake. The OS2-GM32X also provides a secondary output for adding an

optional PAC Steering Wheel Control (SWC) retention interface (SWI-RC, SWI-CP2, SWI-X).

1. Use the 4-position selector switch located on the side of the interface to select the best chime output volume for your specic

installation. Setting 1 being loudest and 4 being softest.

2. In order for the Brown mute wire to output a signal, the Brown / White mute loop on the interface connector must be cut.

3. The SWC will not control the aftermarket radio when OnStar is active.

4. The voice button on the SWC will only control OnStar and cannot be used to control the aftermarket radio.

5. The OnStar volume can be adjusted using the volume SWC when OnStar is active.

6. You can use either the analog VSS or the Data-Bus driven VSS.

If you are using the Brown mute wire, the Brown / White mute loop must be cut in order for this wire to output a signal. PLEASE NOTE: If you cut the mute loop be sure to insulate these wires properly as they are part of a 12v circuit. Do not connect either side of this loop to your aftermarket radio. 3.
