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

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 our 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 dip switches. Consult the dipswitch selection guide to select the appropriate configuration. To activate a dipswitch, press it downward into the ‘ON’ position.

INSTALLATION

1. Take the interface, then connect the head unit connection lead and the 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, utilizing 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 labeled 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 yellow/black Fibre Amp retention connector to the power connector that was previously disconnected from the back of the head unit.

5. Remove the kick panel beneath the glove box and route the Blue/White CAN wire behind the dashboard, bringing it out under the glove box. Plug the Blue/White connector into an empty slot in the CAN Hub.

6. Connect the flying wires on the harness to the rear of the stereo (iff applicable).

7. Connect the antenna adapter to the vehicle’s existing connection at the rear of the aftermarket stereo.

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.

INSTALLING THE FIBRE-OPTIC CABLE
To adapt to the MOST interface, you must remove the original fiber-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 fiber-optic connector: Using a pick tool, carefully pull the tab toward the outer edge of the connector housing. Gently remove the grey fiber-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 fiber-optic cables into the MOST interface’s black connector housing in place of the grey connector. (Image C)
