Installation

It is highly advisable to read the following steps beforehand, to ensure a clear understanding of what is to be expected. The following steps must be done in the order that they are numbered.

With the vehicle completely off:

Touchscreen display

1. Connect the 16-pin harness with stripped leads into port “B” in the touchscreen display.
2. Connect the 5840 harness to the wiring harnesses in the vehicle. These harnesses are the ones removed in step 13 of dash disassembly. Then insert the 5840 harness into port “A” in the touchscreen display. But do not install this harness until exactly before step 1 of Programming section. This is a timed process.
3. Connect the 4-pin harness with yellow RCA jacks into port “C” in the touchscreen display.
4. Disregard ports “D” and “E”, they will not be used in this application.
5. Port “F” is an update port for future firmware upgrades.

HVAC interface

1. Connect the HVAC interface harness into the HVAC interface, and then to the wiring harnesses in the vehicle. These harnesses are the ones removed in step 11 of dash disassembly.
2. Then connect the 10-pin harness into the engine start/stop circuit board assembly.
   Attention: There are (2) 10-pin connectors, one in the engine start/stop circuit board assembly, and one in the touchscreen display. Use only the appropriate connector and disregard the other one. If the incorrect port is accidentally used, the vehicle will need to be reset by removing the battery for a couple minutes.
3. Note: Disregard the 4-pin flat to 4-pin stacked harness, it will not be used in this application.
4. Connect the 6-pin harness from the 5840 harness to the HVAC interface.
5. Connect the female connector of the 54-pin backup camera harness, to the wiring harness in the vehicle. This connector is located behind the factory display screen, which was removed in step 12 of dash disassembly.
   Note: Disregard the male connector, it will not be used in this application.
6. Locate the factory antenna connector in the dash and complete all necessary connections to the radio. Use the antenna adapter provided to adapt the factory antenna connector to the aftermarket radio.

Programming

1. Refer to step 2 from the Installation section.
2. Press the push-to-start button to start the vehicle.
3. Program the kit:
   a. Once the touchscreen display loads up, select the vehicle type.
   b. Wait until the radio comes on, and the touchscreen display shows SWC Configured. This process may take up to 3 minutes.
   Note: If the touchscreen display does not load up, or the radio doesn't come on within 3 minutes, and/or the touchscreen display does not show SWC Configured, check all connections, then reset the interface and try again. Refer to the Troubleshooting section.
4. Cycle the key off. If the driver's door is closed, open and close the door. Cycle the key back on.
5. Test all functions of the installation for proper operation, before reassembling the dash.

Final Assembly

1. Connect the USB cable attached to the radio trim panel with touchscreen display, to the USB port in the back of the radio, if applicable.
2. Secure the completed assembly into the upper dash using the factory hardware removed in step 12 of dash disassembly.
3. Snap the radio trim panel with touchscreen display over the completed assembly, and then reassemble the dash in reverse order of disassembly.

The interface has the capability to assign two functions to a single button, except Volume-Up and Volume-Down. Follow the prompts on the touchscreen display to program the button(s) to your liking.
Note: Seek-Up and Seek-Down come programmed as Preset-Up and Preset-Down for a long button press.

Select Radio

• To show which brand radio is "auto detected" to the interface, press the “Autodetect” button. The radio detected will have a filled in circle. If the incorrect radio is shown, select the proper radio.
• Following is a list of radio manufacturers that the interface presently acknowledges. Others may be added at a later date. Universal “2 or 3 wire” radios can show up as any of these radio manufacturers.

Radios Detected by Interface

*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 function, refer to the Changing Radio Type document 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 document available at axxessinterfaces.com.
