SETTING THE AFTERMARKET RADIO BRAND
With the key in the off position, set the DIP switches to the corresponding
radio listed below.
3.5MM SWC CABLE
The SWRGM-49 Module allows for both types of connections:

wire is attached)
OPTION B is used for BOSS, DUAL, FAHRENHEIT, JENSEN, POWER ACOUSTIK,
PIONEER, SONY and SOUND STREAM units.
NOTE: Cap or insulate the 3.5mm plug or Blue/Yellow wire if not being

Selecting the Audio System
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

module. The module is also labeled Bose and Non Bose to a oid onfusion. (see

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. 
CHIME VOLUME ADJUSTMENT
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.
Backup Camera Connection
You can retain use of the factory backup camera by using the CRUX2543 harness
provided in the kit. See below for connection instructions.
