Steering Wheel Control Adapter for Audi ACV SWC 42SAD003-0

Retain the original functions of steering wheel radio control when replacing the original radio with an aftermarket unit. Depending on the vehicle's equipment, the range of functions, and the software of the newly installed radio, some functions may be limited or replaced by others. Compare the displayed connector cables with the connectors in your vehicle to ensure they match both technically and visually. Check if any of the listed OEM radios were originally installed. Before final installation, verify the vehicle's functionality, system settings, and correct operation of the steering wheel control (SWC).

General Installation Guidelines

Verification Before Installation:

1. Check all control functions and vehicle settings with the original OEM head unit.
2. Remove the original radio (OEM HU) without power.
3. Verify all interface connections for correct wiring – without power.

Connection and Wiring Order:

1. Set up and configure the interface hardware without power.
2. Check the configuration of the connection cable to the HU.
3. Connect the cable to the HU according to the aftermarket device instructions.
4. Connect other wires according to the device instructions.
5. Connect the entire installation to the vehicle – the main power connection should be the last to connect.
6. Perform software configuration of the interface according to the product description and BDA.
7. Configure the aftermarket HU (steering wheel control, camera, hands-free, antenna power, and more).
8. Perform a functional test of the steering wheel control and vehicle communication.

Changing Interface Configuration and HU Cable:

• All changes should be made without power.
• After changes, repeat steps 5 to 8 mentioned above.

In Case of Interface or Vehicle System Failure:

• Return the original OEM HU to the vehicle.
• Start the original unit.
• Induce the rest (sleep) of the CAN Bus system.
• Check the HW configuration of the interface.
• After the CAN Bus calms, repeat steps 5 to 8 mentioned above.

For Connection or Wiring Modifications:

• Only professionally trained personnel are allowed to perform connections and modifications.
• All changes must be verified for manufacturer approval or warranty impact before connecting.
• All modifications must be verified by measurement and comparison with the vehicle's wiring diagram before connecting.
• Modifications are made at your own risk, without warranty of functionality.
• Modifications are conducted at your own risk, without guarantee of eliminating vehicle, device, or interface damage.
• Modifications to pre-installed wiring may lead to a loss of product warranty.
