If the vehicle is equipped with a Bose system, the SWRGM-49 has a built-in Bose adaptor that allows the proper
audio input gain from the aftermarket radio to the Bose amplifier. To use this feature, plug in the male 8-pin
connector on the harness to the GRAY female 8-pin connector on the GM-49 module. The module is also labeled
“Bose” and “Non Bose” to avoid confusion. (see picture below)
If the vehicle is NOT equipped with a Bose system, plug in the male 8-pin connector to the BLACK female 8-pin on
the GM-49 module.
The SWRGM-49 has a potentiometer to adjust the chime volume. It is set at half way by default. To adjust the
volume, simply use a suitable screw driver and turn the potentiometer clockwise to increase the volume and
counter-clockwise to decrease the volume.
You can retain use of the factory backup camera by using the CRUX2543 harness provided in the kit. See below for
connection instructions. (Note: Loose wires may not be needed in the installation.)
