A solution of this type allows for maintaining the factory look of the cockpit while expanding the functionality of the sound system. The port is integrated with the wiring and connectors provided by the manufacturer, which promotes stable system operation and limits the risk of signal interference.

Construction and integration with the electrical system

The component belongs to the Cables, harnesses, and connectors group, meaning it is designed to work with the vehicle's factory electrical installation. The connectors used are matched to the original sockets in the Smart Fortwo C451, which facilitates installation and limits the need for modifications. Key design features of this type of port include:

• dedicated connectors matching the Fortwo C451 model's installation,
• stable connection of wires to the USB AUX port panel,
• pin layout adapted to the requirements of the Smart audio system. This configuration promotes secure seating in the mounting location and proper cooperation with other elements of the electrical harness.
