Purpose and function of the USB/AUX socket

The presented socket with wiring harness is designed for BMW E60, E61, E81, E87, E90, and E91 series models, where a stable, wired connection of external devices to the factory multimedia system is required. The set combines a USB and AUX input, which allows for:

• connecting memory sticks or mobile devices via USB,
• audio signal transmission via a classic AUX connector,
• maintaining an aesthetic, factory-look interior. Thanks to the use of a dedicated wiring harness, signals are routed in an orderly manner, which promotes system stability and reduces the risk of interference.

Construction, color, and interior integration

The element is made in black, which facilitates discreet integration into the center console or other factory-provided mounting locations. The neutral color scheme blends well with typical BMW interior finishes, ensuring the socket does not stand out from other equipment elements. The wiring harness is factory-terminated with appropriate connectors, which promotes proper integration with the vehicle's installation. This type of solution is particularly beneficial when replacing a damaged module or retrofitting the car with additional multimedia inputs, without the need to create custom connections.

Benefits of using an original BMW module

Choosing an original BMW solution from the Electronic control modules and controllers group allows for maintaining compatibility with the vehicle's factory electrical architecture. The most important advantages include:

• secure fit to the intended mounting locations in the listed models,
• stylistic consistency with other cockpit elements,
• maintaining audio system functionality according to the manufacturer's specifications,
• reducing the risk of compatibility issues compared to universal solutions. This approach is particularly important in vehicles where maintaining the original equipment configuration and proper cooperation with other electronic modules is a priority.

Condition, service application, and part selection

The offered item is used, making it an attractive cost-effective alternative for repairs and upgrades of the multimedia system. It works well both for replacing a damaged socket and for retrofitting the car with additional inputs, provided the vehicle configuration allows it. Before purchasing, it is worth verifying compatibility with the specific equipment version and the car's production year using the OEM part number and available replacement numbers in the specification section. This allows for precise component selection for a given vehicle, which is crucial in the case of onboard electronics. If you are planning a comprehensive repair or upgrade of the multimedia installation area in your BMW and need other elements from the same group, such as control modules, interfaces, or additional connectors, check the available parts in the BMW electronic control modules and controllers category.
