Prior to Installation

Installation requires a certain level of technical knowledge. It is important to read the manual before installation. Select a location for installation that is dry and free from heat sources. Use the correct tools during installation to prevent any damage to the vehicle or the product. Aerpro cannot be held liable for any issues arising from improper installation.

Before proceeding with installation, disconnect the negative battery terminal and ensure the key is removed from the ignition.

Interface Features Explained

KEY1 and KEY2

KEY1 and KEY2 are specifically tailored for analog learning mode-style radios. The SWC module is designed with a resistor chain that precisely matches the required resistance for seamless compatibility with this type of head unit.

KEY1 and KEY2 EXTEND

This mode extends every button press to 2 seconds during the learning process. However, with rotary wheel-designed steering wheel buttons, holding for 2 seconds isn't feasible. The KEY1 and KEY2 extend feature addresses this by automatically prolonging each press, simplifying head unit programming even in such scenarios. Extend mode is not intended for normal use; it is only used in the teaching process.

ANALOG SINGLE WIRE and ANALOG SINGLE WIRE EXTEND

This function operates similarly to KEY1 and KEY2 but transmits all unique values through the IR SWC single wire. This is crucial for compatibility with learning-style head units featuring only one learning input wire. To ensure compatibility, this feature has been incorporated into the steering wheel control interface, ensuring seamless operation across various head unit setups. The Analog Extend mode functions identically to its counterpart within the KEY1 and KEY2 system but transmits through a single wire.

SWC Interface Components

The SWC interface consists of the following main components:

• 18-PIN HARNESS CONNECTOR: Connects to the vehicle harness.
• DIPSWITCHES: Used for configuring the interface.
• 16-PIN HEAD UNIT CONNECTION LEAD: Connects to the aftermarket stereo.
• USB-C: For software updates.

Connection Guide

Before Installation

Prior to installing the interface, it is essential to remove and disconnect the factory stereo. For guidance on this process, refer to the vehicle owner's manual/handbook or seek assistance from a professional.

Setting the Dipswitches

This interface includes a set of dipswitches. Consult the dipswitch selection guide to select the appropriate configuration. To activate a dipswitch, press it downward into the 'ON' position. Refer to the diagram for an example of the 'KENWOOD1' dipswitch configuration.

Installation Steps

1. Take the interface, then connect the 16-PIN head unit connection lead and the 18-PIN steering wheel harness connectors to their respective ports.
2. Connect the head unit connection lead to the steering wheel remote input on the rear side of the aftermarket stereo. Connection methods vary based on the stereo brand, utilising either a 3.5mm jack connector SWC IR wire or wired inputs KEY1 and KEY2. For specific connection guidance, refer to your aftermarket stereo's installation manual if not clearly labelled on the stereo harness.
3. Connect the power/speaker ISO connector from the interface to the corresponding power/speaker ISO connection on the aftermarket stereo. For aftermarket stereos lacking an ISO connector, refer to the "Wiring Key" on Page 2 for guidance on connecting wires. Certain interfaces may also include extra "flying" wires for additional functionalities such as parking brake trigger, reverse gear, and speed pulse. Further information on these wires is available in the "Flying Wire Wiring Key" section.
4. Connect the vehicle-specific connectors from the interface harness to the corresponding connectors on the vehicle harness.
5. Connect the flying wires on the harness to the rear of the stereo (if applicable).
6. Connect the antenna adapter to the vehicle's existing connection at the rear of the aftermarket stereo.
7. When installing an aftermarket reverse camera, connect the yellow RCA from the harness to the yellow RCA of the aftermarket camera. (If supported by the interface and vehicle)
8. When installing a DAB antenna, ensure to connect the DAB aerial connector to the rear of the new stereo.
9. After connecting all wires (along with any additional accessories), it's crucial to thoroughly test the stereo and steering wheel controls before reassembling the dashboard. If steering wheel controls are unresponsive, inspect connections and check dipswitch settings. Repeat the connection process if necessary, following the outlined steps.

Steering Wheel Control Configuration

The following diagram illustrates common steering wheel control functions. Actual configurations may vary depending on the vehicle.

• A Volume Up
• B Volume Down
• C Track Up
• D Track Down
• E Source
• F Voice Control
• G Pick Up
• H Hang Up

Button Remapping

The steering wheel buttons offer flexibility for re-configuration or assignment of dual functions, depending on the vehicle and aftermarket radio support. Each button can be programmed for both a short press and a long press command. Bespoke configurations can be created. Button configuration can be done via PC, MAC, or smartphone through the USB port. Detailed instructions are available on the Aerpro website.

Connection Diagram Overview

The connection diagram visually represents the interface's integration points.

Head Unit Connection Lead

This lead connects to the aftermarket stereo and includes wires for Ground, Key 2, Key 1, SWC IR, and a 3.5mm jack plug. It connects to the stereo via a 16-pin harness connector.

SWC Interface

This is the central module featuring dipswitches for configuration and a USB-C port for updates. It connects to the head unit lead and the vehicle harness.

SWC Vehicle Harness

This harness connects to the vehicle's factory wiring. It includes an ISO connector for radio harness connection and a vehicle connector for direct vehicle harness connection. The 18-pin harness connector links to the SWC interface.

Note: Harness wire colours are for illustration purposes only and may differ from the actual harness.
