If the vehicle is equipped with a Bose system, the SWRGM-51 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-51 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
connector on the GM-51 module.
The SWRGM-51 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.
