Original Origin and Replacement Numbers

The presented controller comes from the BMW OE line, which means it adheres to factory quality, compatibility, and software standards. The module has a dedicated OEM part number and assigned replacement numbers, allowing it to be used as a substitute in various equipment configurations, provided the designations used in the specific vehicle match.

The presence of reference numbers enables precise matching of the module to a specific equipment version, minimizing the risk of communication problems within the vehicle network and facilitating diagnostic work for BMW specialists.

Condition, Selection, and Installation in the Vehicle

The module is offered as a used original part, which translates to a favorable cost-to-functionality ratio while maintaining factory specifications. Before installation, it is recommended to verify the compatibility of the OEM part number and replacement numbers with the vehicle's data, and to consult with an automotive electrician or BMW service regarding potential software adaptation.

When planning a replacement, it is worth considering:

• compatibility of equipment versions (audio system, presence of iDrive, type of wiring harness),
• condition of the electrical harness and connectors in the car,
• the need for module coding or programming after installation.

Benefits of Using an Original BMW Module

Using a factory BMW Bluetooth controller ensures stable connectivity system operation and proper cooperation with other vehicle controllers. An original module is designed for a specific electrical architecture, reducing the risk of interference, dashboard errors, or software update issues.

Compared to universal solutions, the original controller:

• maintains full integration with the factory BMW interface,
• does not require modifications to the wiring harness beyond the standard installation procedure,
• allows for maintaining the vehicle's functional consistency, which is important for further diagnostics and servicing.
