Important – MOST25 Compatibility

This converter is designed for compatible MOST25 fibre-optic systems. It is not a D2B converter.

Mercedes-Benz and Porsche vehicles may use different audio networks depending on the model, production year, original head unit and factory sound system.

MOST25 and D2B systems are different and the converters are not interchangeable.

Before purchasing, please confirm:

• Vehicle make, model and production year
• Factory radio/head unit
• Factory amplifier or BOSE system
• Fibre-optic connector type
• Existing wiring and connections
• MOST25 system compatibility

If you are unsure about compatibility, we recommend providing your vehicle details and clear photographs of the original radio, amplifier and fibre-optic connections before ordering.

Installation

Professional installation is strongly recommended.

Installation requirements may vary depending on the aftermarket head unit and the vehicle's original audio configuration. Additional wiring, adapters or configuration may be required.
