			Specific SWC
			Interface

•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		SUB
use this cable. To ensure best sound
performance channel summing is	Center
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).
