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.

Important! Reset OnStar® by turning the ignition off for at least two minutes prior to testing.

Step #1: Adjusting the OEM-1 level controls.

After all connections are made and plugged in, turn on the aftermarket stereo. Adjust the volume on the radio and the OEM-1 level

Step #2: Adjusting OS-1 Volume and Testing Operation with OnStar

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

button on the vehicle will end the call and the OS-1 LED will turn off. After a few seconds the stereo should resume playing or will

turn back on.
