Vehicle placement and integration

The presented module is intended for installation in the rear part of the vehicle, in accordance with the factory design for electronics placement in the Mercedes W204. This location promotes stable operating conditions for the controller, limits exposure to vibrations from the engine compartment area, and facilitates the routing of wiring harnesses between the head unit and other system components.

Integration with the vehicle's installation is carried out via dedicated connectors, which allows for maintaining the factory connection standard. In practice, this translates into:
