PROGRAMMING

With the key in the off position:

Connect the 16-pin harness with stripped leads, and the car side harness, into the Axxess interface.
Connect the climate control harness to the radio trim panel with climate controls, then to the wiring harness in the vehicle.
Locate the factory antenna connector in the dash and complete all necessary connections to the radio. Metra recommends using the proper antenna adapter from Metra.

Attention! Do not connect the car side harness to the wiring harness in the vehicle just yet.

PROGRAMMING THE INTERFACE
For the steps below, the L.E.D. located inside the interface can only be seen while active. The interface does not need to be opened to see the L.E.D.

Start the vehicle.
Connect the car side harness to the wiring harness in the vehicle. The L.E.D. will initially be solid Green to indicate the interface is powered.
The L.E.D. will then flash Red up to (23) times indicating which radio is connected to the interface, and then turn off for a couple of seconds. Pay close attention to how many Red flashes there are. This will help in troubleshooting, if need be. Refer to the L.E.D. feedback section for more information.
After several seconds the L.E.D. will turn on solid Red while the interface auto detects the vehicle. The radio will shut off at this point. This process should take (5 to 30) seconds.
- Once the vehicle has been auto detected by the interface, the L.E.D. will turn on solid Green, and the radio will come back on, indicating programming was successful.
Test all functions of the installation for proper operation, before reassembling the dash. If the interface fails to function, refer to Resetting the Interface.
Note: The L.E.D. will turn on solid Green for a moment, and then turn off under normal operation after the key has been cycled.
Test all functions of the installation for proper operation, before reassembling the dash.. If the interface fails to function, refer to “Troubleshooting”, “Resetting the Axxess interface”.

Chime level adjustment:

With the vehicle on, turn it off and leave the keys in ignition. Open the driverâ€™s door; chimes will be heard.
Wait (10) seconds, and then with a small flat-blade screwdriver, turn the potentiometer clockwise to raise the chime level; counterclockwise to lower the chime level.
When the chime is at a desired level, remove the keys from the ignition. This will lock the chime volume at its current level.

PROGRAMMING (CONT.)

Press the OnStar button to activate it.
While OnStar is speaking, press the VOLUME-UP or VOLUME-DOWN button on the steering wheel to raise or lower the OnStar level.
If the vehicle doesn’t come equipped with steering wheel controls, locate the Black/Yellow wire on the car side harness.
While OnStar is speaking, tap the Black/Yellow wire to ground. Once the OnStar level is set, it will stay at that level until the Black/Yellow wire is tapped to ground again.

STEERING WHEEL CONTROL SETTINGS

L.E.D. Feedback: The (23) Red L.E.D. flashes represent a different radio manufacturer for the SWC interface to detect. For example, if you are installing a JVC radio, the SWC interface will flash Red (5) times, then stop. Following is the L.E.D Feedback Legend, which indicates the flash count of the radio manufacturer.

KEYNOTES

If the SWC interface flashes Red (7) times, and an Alpine radio is not installed, that means there is an open connection not accounted for. Verify that the 3.5mm jack is connected to the correct steering wheel jack/wire in the radio.
The AXSWCH-PAR is required (sold separately). Also, the software in the radio must be rev. 2.1.4 or higher.
If a Clarion or Eclipse radio is installed and the steering wheel controls do not function, change the radio to Clarion (type 2) or Eclipse (type 2) respectively. If the steering wheel controls still
do not function, refer to the Changing Radio Type document on the next page, also available at axxessinterfaces.com.
If a Kenwood radio is installed and the L.E.D. feedback flashes (5) times instead of (2), manually change the radio type to Kenwood. To do this, refer to the Changing Radio Type instructions on the next page, also available at axxessinterfaces.com.

STEERING WHEEL CONTROL SETTINGS (CONT.)

Changing Radio Type

If the LED flashes do not match the number of the aftermarket radio, the radio will have to be manually programmed.
Three (3) seconds after turning the key on, press and hold the Volume-Down button on the steering wheel until the L.E.D. in the interface turns a solid green.
Release the Volume-Down button; the L.E.D. will go out indicating we are now in Changing Radio Type mode.
Refer to the Radio Legend to know how many flashes are required to reach the after-market radio.
Press and hold the Volume-Up button until the L.E.D. goes solid, and then release. Repeat this step for the desired radio number you have selected.
Once the desired radio number has been selected, press and hold the Volume-Down button on the steering wheel until the L.E.D. goes solid. The L.E.D. will remain on for about (3) seconds, while it stores the new radio information.
Once the L.E.D. goes off, the Changing Radio Type mode will then end. You can now test the steering wheel controls.

Note: If at any time the user fails to press any button for a period longer than (10) seconds, this process will abort.
Note: Refer to L.E.D. Feedback Legend for number of flashes, and for more information regarding specific radios.

Dual assignment instructions (long button press)
The interface has the capability to assign (2) functions to a single button, except Volume- Up and Volume-Down. Follow the steps below to program the button(s) to your preference.

No te: Seek-Up and Seek-Down come pre-programmed as Preset-Up and Preset-Down for a long button press.

Turn on the ignition but do not start the vehicle.
Press and hold down the steering wheel control button that you want to assign a long press function to for about (10) seconds, or until the L.E.D. flashes rapidly. At this point release the button; the L.E.D. will then go solid.
Press and release the Volume-Up button the number of times corresponding to the new button number selected. Refer to the Dual Assignment Legend. The L.E.D. will flash rapidly while the Volume-Up button is being pressed, and then go back to a solid L.E.D. once released. Go to the next step once the Volume-Up button has been pressed the desired number of times.
Caution: If more than (10) seconds elapses between pressing the Volume-Up button, this procedure will abort, and the L.E.D. will go out.
To store the long press button in memory, press the button that you assigned a long press button to (the button held down in Step 2). The L.E.D. will now go off indicating the new information has been stored.

Note: These steps must be repeated for each button you would like to assign a dual purpose feature to. To reset a button back to its default state, repeat Step 1, and then press the Volume-Down button. The L.E.D. will go out, and the long press mapping for that button will be erased.

Remapping the steering wheel control buttons
The interface makes it possible to change the button assignments on the steering wheel. For example, the Seek-Up button could be reassigned as the Mute button. Follow the steps below to remap the steering wheel control buttons:

Turn off the radio and ensure that the LED light on the interface is visible to confirm button recognition
Within the first (20) seconds of turning the ignition on, press and hold the Volume-Up button on the steering wheel until the L.E.D. goes solid.
Release the Volume-Up button, the L.E.D. will then go out; The Volume-Up button has now been programmed.
Follow the list in the Button Assignment Legend to reference the order in which the steering wheel control buttons need to be programmed.
Note: If the next function on the list is not on the steering wheel, press the Volume-Up button for (1) second until the L.E.D. comes on, and then release the Volume-Up button. This will tell the interface that this function is not available and it will move on to the next function.
To complete the remapping process, press and hold the Volume-Up button on the steering wheel until the L.E.D. in the interface goes out.
