• Proper visual fit – the control panel maintains the original look of the cockpit without interfering with the interior styling.
• Stable operation of the multimedia system – maintaining the functions and ergonomics intended by the manufacturer.

Such a solution is particularly important in premium class cars, where electronics are responsible not only for comfort but also for many functions related to vehicle safety and communication.

To fully utilize the potential of this module, installation by a workshop with experience in Mercedes electronics is recommended. This allows for:

• proper connection to the vehicle's electrical system,
• potential adaptation or configuration using appropriate diagnostic software,
