Purpose and function of the Bluetooth antenna cable

The Bluetooth antenna cable in the Mercedes W205 is responsible for the correct signal transmission between the communication module and the antenna. In practice, this means more stable pairing of mobile devices, less susceptibility to interference, and predictable operation of the hands-free system and audio streaming. Using an original component allows you to maintain compatibility with the vehicle's factory electrical architecture.

Benefits of using an original cable

Choosing a Bluetooth antenna cable dedicated to the W205 series is a solution that reduces the risk of compatibility and connector fitment issues. The original geometry of the harness and the correct type of terminals speed up installation and facilitate routing the cable along factory paths. For workshops and users, this means:

• maintaining the factory harness routing in the body,
• a secure connection to the Bluetooth module and antenna,
• reduced risk of looseness and abrasion during operation.

Condition of the item and installation aspects

The offered cable comes from disassembly, which allows for an economical repair of the connectivity system while maintaining the manufacturer's original specifications. The item is intended for installation in place of the factory cable, without the need for modifying the installation or using adapters. In practice, this comes down to recreating the original cable routing and correctly connecting the terminals in accordance with the layout used in the Mercedes W205.

Application in Mercedes multimedia systems

A functional Bluetooth antenna cable has a direct impact on the quality of the multimedia system – from the hands-free set, through music streaming, to phone integration with the vehicle interface. In the case of symptoms such as connection drops, poor range, or problems with device pairing, replacing the cable is one of the basic diagnostic steps that allow for restoring system stability.
