Purpose and function of the module

The presented Mercedes C205 W213 USB SD Card Module Multimedia Reader Port Socket is a component that integrates data ports with the vehicle's factory multimedia system. It is responsible for stable communication between external media and the head unit, which translates into correct music playback, file access, and support for system functions provided by the manufacturer.

Its placement in the front interior area ensures quick access to the connectors for the driver and passenger, without the need for interference with the electrical installation or additional modifications. The module is designed as an OEM solution, ensuring consistency with the dashboard and other console elements.

Construction and integration with the vehicle installation

The module acts as an interface between the physical USB/SD slots and the onboard electronics. The applied design allows for:

• secure seating in the factory mounting location in the front of the vehicle,
• mechanical fitment to the center console panel or glove box (depending on the equipment version),
• electrical integration with the wiring harness intended for the multimedia system in the C-Class C205 and E-Class W213.

As a result, installation usually comes down to connecting the dedicated harness and seating the module in the socket, without the need to modify the installation or use universal adapters.

Application in diagnostics and multimedia upgrades

A functional Mercedes C205 W213 USB SD Card Module Multimedia Reader Port Socket is important not only for multimedia user comfort but also for handling service data and updates. In many vehicle configurations, these ports are used for:

• uploading map and multimedia system software updates,
• reading and writing user data (playlists, settings),
• functional tests during electronic system diagnostics.

Replacing a faulty module with an original part from the same group allows for restoring full system functionality without interfering with the head unit or wiring harnesses, which is cost-effective and time-efficient.

Product characteristics and condition

The offered item comes from a Mercedes vehicle and is classified in the Electronic control modules and controllers group. The placement defined as front means that the module is intended for installation in the front part of the cabin, in the zone accessible to the driver and passenger. The product is used, which in practice means it comes from dismantling and may show signs of wear, while maintaining the functionality required for further use.

To facilitate identification in the store system, an SKU designation has been used, and the technical specification also includes the OEM part number and related interchangeable numbers. This allows for precise matching of the module to the specific equipment configuration in the Mercedes C-Class C205 and E-Class W213.

Selection, compatibility, and additional materials

When selecting a USB/SD reader module for a specific vehicle, it is crucial to compare the part number and the multimedia system equipment version. In case of doubt, it is worth checking the data against service documentation or the number found on the currently installed module to avoid compatibility issues.
