PROGRAMMING THE INTERFACE AND CLIMATE DISPLAY
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 7390 harness to the wiring harness in the vehicle.
• The L.E.D. will initially turn on solid Green, then turn off for a few seconds while it auto
detects the radio installed.
• The L.E.D. will then flash Red up to (18) 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 a couple 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.
Refer to “Steering Wheel Control Settings” for customizing the buttons, if so desired.
• 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.
1. Secure the climate control assembly to the dash in reverse order of disassembly using the
factory screws.
2. Secure the radio assembly to the dash using the factory screws.
3. Reassemble the dash in reverse order of disassembly to complete the installation.
FINAL ASSEMBLY
Programming the climate display:
7. Turn the parking lights on.
8. Turn the vehicles light dimmer all the way down, then all the way up.
9. Turn the lights off.
10. Test all functions of the installation for proper operation, before reassembling the dash.

STEERING WHEEL CONTROL SETTINGS
L.E.D. feedback
The (18) Red L.E.D. flashes represent what brand radio the ASWC-1 believes it is connected to.
Each flash represents a different radio Manufacturer. For example, if you are installing a JVC
radio, the ASWC-1 will flash Red (5) times, and then stop. Following is a legend that dictates
which radio Manufacturer corresponds to which flash.
* Note: If the Axxess interface flashes Red (7) times, and you do not have an Alpine radio
connected to it, that means the Axxess interface does not detect a radio connected to it. Verify
that the 3.5mm jack is connected to the correct steering wheel jack/wire in the radio.
** Note: The AX-SWC-PARROT is required (sold separately). Also, the Parrot radio must be
updated to rev. 2.1.4 or higher through www.parrot.com.
† Note: If you have a Clarion radio and the steering wheel controls do not work, change the radio
type to the other Clarion radio type; same for Eclipse. The following section explains how to do
this.
‡ Note: If you have a Kenwood radio and the L.E.D. feedback comes back showing as a JVC radio,
change the radio type to Kenwood. The following section explains how to do this.
Attention: The Axxess Updater App can also be used to program the following (3)
sub-sections as well, pending that the Axxess interface has been programmed.

Changing radio type
If the L.E.D. flashes do not match the radio you have connected, you must manually program the
Axxess interface to tell it what radio it is connected to.
1. After (3) seconds of turning the key on, press and hold the “Volume-Down” button on the
steering wheel until the L.E.D. in the Axxess interface goes solid.
2. Release the “Volume-Down” button; the L.E.D. will go out indicating the Axxess interface is
in “Changing Radio Type” mode.
3. Refer to the Radio Legend to know which radio number you would like to have programmed.
4. 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.
5. 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.
6. Once the L.E.D. goes out, the “Changing Radio Type” mode will then end. You can now test
the steering control 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.

Remapping the steering wheel control buttons
Once the ASWC-1 has been programmed, the button assignment for the steering wheel controls
may be reassigned if so desired. For example, if the “Seek-Up” button is preferred to be the
“Mute” button instead. Follow the steps below to remap the steering wheel control buttons.
1. Ensure the Axxess interface is visible so you can see the L.E.D. flashes to confirm
button recognition.
Tip: Turning the radio off is recommended.
2. Within the first twenty seconds of turning the ignition on, press and hold the “Volume-Up”
button on the steering wheel until the L.E.D. goes solid.
3. Release the “Volume-Up” button, the L.E.D. will then go out; The “Volume-Up” button has
now been programmed.
4. Follow the list in the Button Function 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 to skip that function, and then release the
“Volume-Up” button. This will tell the Axxess interface that this function is not available,
and it will move on to the next function.
5. To complete the remapping process, press and hold the “Volume-Up” button until the L.E.D.
in the Axxess interface goes out.
