Dipswitch Configuration

PLEASE NOTE: The dipswitch settings for the MOST SWC interfaces differ from those for the SWC interface range. Please refer to the appropriate dipswitch table in the instruction guides for accurate configuration.

SWC MOST Interface Components

• FIBRE-OPTIC CONNECTOR PORT
• HARNESS CONNECTOR PORT
• HEAD UNIT CONNECTION LEAD PORT
• CAN USB UPDATE
• DIPSWITCHES
• MOST USB UPDATE

Software Update

The interface software can be updated using the two micro USB ports on the device. These ports serve specific purposes: one is dedicated to updating the MOST software, while the other is for updating the CAN Bus software. By connecting to these ports, users can ensure their interface remains up-to-date, maintaining optimal performance and compatibility with their vehicle's systems.

Software update instructions can be found in a separate guide on the ACV website.

Connection Guide

Before Installation

Prior to installing the interface, it is essential to remove and disconnect the factory stereo. For guidance on this process, please 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.

Installation

1. Once the head unit is removed, carefully route the extension cables behind the dashboard and glove compartment, guiding them into the passenger footwell area. Once in place, install the interface following the below steps and connect it to the radio in the footwell taking care to avoid the yellow airbag cables as shown in the image.
2. Take the interface in the footwell of the vehicle, then connect the head unit connection extension lead and the steering wheel harness connectors to their respective ports.
3. 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 or brown SWC IR wire. For specific connection guidance, refer to your aftermarket stereo's installation manual if not clearly labelled on the stereo harness.
4. 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.
5. Connect the vehicle-specific connectors from the interface harness to the corresponding connectors on the vehicle harness.
6. Connect the flying wires on the harness to the rear of the stereo (if applicable).
7. Connect the antenna adapter to the vehicle's existing connection at the rear of the aftermarket stereo.
8. 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)
9. When installing a DAB antenna, ensure to connect the DAB aerial connector to the rear of the new stereo.
10. 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.

Installing the Fibre-Optic Cable

To adapt to the MOST interface, you must remove the original fibre-optic connection.

1. Place the amplifier interface into the black connector housing provided with this kit and snap it into place. (Image A)
2. From the original fibre-optic connector: Using a pick tool, carefully pull the tab toward the outer edge of the connector housing. Gently remove the grey fibre-optic insert from the connector. (Image B)
3. From the MOST interface: Push the tab toward the grey dust cover. Using needle-nose pliers, remove the grey dust cover. Insert the factory fibre-optic cables into the MOST interface's black connector housing in place of the grey connector. (Image C)
