OS-1 BOSE
General Motors OnStar
®
Bose® Interface
Installation Instructions.
The OS-1 BOSE is a plug and play interface kit that allows replacement of a General Motors factory stereo (without RDS option)
and maintain operation of the OnStar® system and the Bose® amplifi er and speakers. The kit includes the OS-1 OnStar®
interface and the OEM-1 premium sound system interface and cable . The OS-1 has on board switching, and amplifi cation to
allow audio from the OnStar® system to play through the two front factory speakers when OnStar® is active, and mute the
new replacement radio. The OS-1 can also be used when a stereo and amplifi er combination system is installed. Separate
speakers can be added if desired.
There are separate gain adjustments for left and right OnStar® audio and an LED indicator that turns on when the OS-1 receives
an “ON” command from the OnStar® system.

Aftermarket stereo
Connecting the aftermarket stereo and OS-1 to the vehicle’s factory Bose system.
Step 1.
Pre wire the OS-RAD wire harness to the aftermarket stereo wire harness. If the aftermarket stereo has a mute wire, cut the
brown wire as close as possible to the relay socket and connect it to the stereo’s mute wire (Fig. 1).
Step 2.
Use the supplied OS-1618 wire harness and connect to the 16 pin connector side to the OS-1. Connect the AMP-GM21A
wire harness and OEM-1 interface to the OS-1 according to diagram below. Connect the AMP-GM21A and OS-GM9 con-
nectors to the factory harness.
NOTES:
WARNING!
(Vehicles equipped with a 9 pin Y connector) Do not unplug the separate 9 pin female and male connectors that are
located farther back in the dash. Doing so will disconnect OnStar® from the OS-GM9 connector.
• Remember to reset OnStar® by turning the ignition off for at least two minutes prior to testing.
• The AMP-GM21A wire harness will ONLY work on a vehicle with a BOSE premium sound system.

®
After all connections are made, push the Blue OnStar
®
button on the vehicle to initiate a call to the service center. The OS-1 LED
will turn on and the the stereo should either mute or turn off and a greeting message should be heard. Adjust the OS-1 volume to
a suitable loudness level. Adjust the audio outputs of the OS-1 with a small fl at head screwdriver. Counter clockwise is at minimum
and clockwise is maximum output. If the volume sounds distorted, lower the outputs of the OS-1. Pressing the black OnStar
®

turn back on.
