The OS-4 is a plug and play interface that allows the replacement of a General Motors GMLAN factory radio. The OS-4 will
maintain operation of the OnStar® system in vehicles with Bose® audio systems, amplifi ed audio systems and also audio
systems without external amplifi ers . The OS-4 has on board switching that allow audio from the OnStar® system to play
through the two front factory speakers. This interface retains all warning chimes, audible turn signal indicators, Bluetooth
and the Vehicle Rear Parking Assist System (if equipped). The factory XM radio tuner can be controlled from the Rear Seat
Entertainment (RSE) Controls. RSE headphone jacks will also remain active and are designed for use with dual zone radios
and the factory installed XM tuner. If the overhead LCD is present the IR headphone system will also be active.

OS-RADPWRAUDIO
• Aftermarket radio connections are made at the 20-pin OS-RADPWRAUDIO connector.
A detailed description of these wires is on the next page.
• If the vehicle has Rear Seat Audio Controls and the XM tuner is serviced plug the 8 pin
XM Audio output cable into the OS-4. The RCA cables will feed the XM audio into the
aftermarket radios AUX input (if available). The XM RCA cables are not necessary for
Rear Seat Audio but will allow the headunit to play the XM audio through the cabin.
• Factory installed audio options such as Bose, Harman Kardon or Pioneer amplifi ers
will determine the 16-pin OS-GMLAN29 connection. If the vehicle has a factory installed
amplifi er use the Factory Amplifi er Audio location. If a factory installed amplifi er is not
present use the Non-Amplifi ed Factory Audio location.
• The OS-NAV connector has VSS, Reverse and Parking Brake outputs as well as the
OnStar push button volume adjustment input.
• If SWC buttons are present and retained using a radio specifi c SWC interface use the
provided plug. No other connections or splices are necessary.
• The CMX retains all factory warning and safety chimes. If the vehicle chimes when the
radio is removed the CMX is not needed.
• The Mute loop (if not cut) will turn the ACC. 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. Vehicle Connections

• The OS-4 provides a SWC output connector attached to the OS-
RADPWRAUDIO harness. For ease of installation, all necessary
connections for a SWI-X, ECL2, JACK, or PS have made for you.
• When using this SWC output connector the radio specifi c SWC interface
must be programmed for version 2 (refer to SWC interface programming
instructions for exact programming sequence).
• Both loops should also remain in tact.
• During steering wheel button assignment programming each button
should be pressed and held for 1 second after the SWC interface LED
goes out with the exception of the Speak button.
• The speak button should be pressed for less than 1 second and
released.
• Pressing the Speak button for longer than 1.5 SEC will activate OnStar.

Using the CMX
• The provided CMX will play all safety/warning
chimes and turn signal/hazard light tones in
vehicles that do not play these chimes/tones when
the factory installed radio is removed.
• When the radio is removed - if factory chimes still
play the CMX is not needed. The CMX cable (2-
pin connector attached to the OS-RADPWRAUDIO
interface harness) should be tied up as it is not
used for any other connections.
• To adjust the level of the warning and safety
chimes refer to the vehicles owner manual for
Driver Information Center (DIC) settings. Not all
vehicles have a DIC. If the DIC is not available the
chime level is not adjustable.
Center and Sub Connections

• Some Cadillac vehicles are
equipped with a Dolby Surround
Sound Amplifi ed Audio System. The
amplifi ers 5.1 mode is enabled when
the RSE system is off and OnStar is
not active. If the aftermarket radio
has a dedicated center channel
and or sub output connect it to the
provided cable as labeled. Refer to
the aftermarket radios owner manual
for surround sound settings and
adjustments.
• If the aftermarket radio to be
installed does not have a dedicated
center channel or sub output do not
use this cable. To ensure best sound
performance channel summing is
not recommended. Use this cable
according to the outputs that are
available.
• This cable can also be used for
factory reverse camera retention if
available and if center channel and
or sub connections are not needed
(see Notes section of this manual).

Installation Notes
1. When the interface is connected to the vehicle for the fi rst time the car must be started so all vehicle features are recognized by the interface.
2. DO NOT cut the Brown loop on the SWC interface connector. Program the radio specifi c SWC Interface for version #2.
3. When the Rear Seat Audio jacks are activated in any vehicle OTHER than the Cadillac Escalade or a UQA amplifi ed vehicle the rear speakers will mute.
4. The headphone jacks will play the rear zone source selected by the head unit (refer to the new radios instruction manual for details on this feature if
equipped). Maximize the rear zone volume level (this will reduce unwanted noise). During an OnStar call the front speakers play OnStar, the rear speakers are
muted and the headphones will continue to play the rear zone audio source.
5. Using the Center and Sub cable for factory reverse camera retention.
