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.

With the supplied brown connector NOT attached to the vehicles brown radio connector: lift the upper and lower locking tabs near the wire insertion part of the supplied brown connector which houses the center and sub RCA cables.

Depress the silver exposed locking tabs on which ever RCA connector (center or sub) is not being used during this installation.

After removing both shield (black) and center conductor (red or white) pins - re-insert as follows (see image aside).

Pin 6 is the camera+ signal and Pin 7 is the camera- signal. After inserting the pins clasp the locking tab back down to lock the moved pins into place.

Fit the modifi ed brown connector into the vehicles brown connector and plug the moved RCA cable into the aftermarket radios camera input (mark this RCA cable for future reference).

Use the supplied reverse output wire (green wire in OS-NAV connector) for automatic switching when the vehicle is put into reverse.

6.DTS, Equinox, Torrent and Vue Installation Notes:

If the vehicle is equipped with a factory amplifi er other than a Bose amplifi er and OnStar audio is not heard during operation the Black/White wire located in the OS-GMLAN29 harness needs to be cut in half and insolated at both ends (c2 vehicle (16pin) connector pin 8) .

Testing and Verifying Operation

1.Turn ignition on. The red ignition LED inside the interface will turn on and the +12v accessory wire will turn on.

2.Turn on the radio and check balancing and fading. Note: The RPO code UQA (standard digital Bose® amplifier) will not fade as the rear outputs of aftermarket radio do not adjust the amplifi er.

3.Pressing the OnStar® button will turn off the rear speakers and allow the OnStar® audio to be heard in the two front speakers. The OnStar® active red LED will also turn on. When OnStar® disconnects, the radio will un-mute or turn back on and the OnStar® LED will turn off.

4.Turn off vehicle and remove key. RAP will be active and keep the radio on for 10 minutes or until the drivers door is opened.

5.The red ignition On LED and radio will turn off when RAP turns off or the drivers door is opened.

6.Pressing the Mute/OnStar® button on the steering wheel for 1.5 seconds will also activate Onstar®.
