Installation Steps

1.  The radio select rotary switch on the side of the interface must be adjusted to the proper radio 

setting before plugging the interface into the vehicle.

2.  Make all connections as described in the chart on page 1

3.  Factory installed amplifiers will determine the audio output connection.  If the vehicle has a factory installed amplifier use the 

factory amplifier audio location.  If a factory installed amplifier is not present use the non-amplified factory audio location.

4.  If the aftermarket radio is equipped with an auxiliary input and you wish to retain the factory RSE audio, plug the RCA 

connectors from the  secondary harness into the radios auxiliary input.

5.  Plug the CMX chime module in if necessary (If the vehicle chimes when the radio is removed the CMX is not necessary). 

PLEASE NOTE:

 In order to get the best possible sound out of the CMX please mount it in a place free and clear of any 

obstructions, preferably as close as possible to the bottom of the dash pointing down toward the floor of the vehicle.

6.  The Mute loop (if not cut) will turn the accessory output off when an OnStar or Bluetooth call is made or received.  If the 

aftermarket radio has a mute input cut this loop and connect the outer brown wire to the mute input.

7.  Connect the SWC wire according to the chart on page 1 (aftermarket radio MUST support a wired remote input).
8.  If you wish to reassign functions to the SWC follow the programming instructions on the next page.

IMPORTANT! 

The interface comes pre-programmed for the functions listed in the chart below and does not require programming 

unless you wish to re-assign the SWC functions to different buttons. The SWC can always be restored to default settings by 

pressing  the program button on the side of the interface once and waiting seven seconds for the LED to flash three times.
