Keep the original vehicle amplifier working when upgrading the factory screen or head unit.
This optical fiber audio decoding box converts an external RCA audio signal into an optical fiber signal and transmits it to the vehicle amplifier through the original optical fiber system.
It is designed for selected Mercedes-Benz vehicles and can help retain the original amplifier when replacing the factory multimedia screen or head unit.
If there is no sound after installing the fiber optic box, check the following connections:
The optical fiber audio decoding box is installed between the aftermarket multimedia system and the vehicle's original audio system. It converts the external RCA audio output into an optical fiber signal that can be transmitted to the original vehicle amplifier.
When replacing the original factory screen or head unit, this fiber decoder box can be used to retain the original vehicle amplifier while providing audio from the replacement multimedia system.
According to the product information, the decoder box is applicable to the following Mercedes-Benz vehicles:
Power: Yellow wire to 12V battery power. Black wire to ground.
CAN Bus: Connect CAN-H and CAN-L according to the vehicle system.
Installation Location: Behind the vehicle audio screen/head unit or near the vehicle power amplifier.
The vehicle's optical fiber communication system must operate normally for audio signal transmission to work correctly.
It converts an external RCA audio signal into an optical fiber signal and transmits the signal to the vehicle amplifier through the original optical fiber system.
The decoder box is designed to help retain the original vehicle amplifier when replacing the factory multimedia screen or head unit on compatible vehicles.
It can be installed behind the vehicle audio screen or head unit, or near the vehicle power amplifier.
The yellow wire connects to 12V battery power and the black wire connects to ground. The ACC power supply does not need to be connected.
Check the 12V power and ground connections first, then confirm the CAN-H and CAN-L connections. The vehicle's optical fiber communication system must also operate normally.
The listed applications include selected S/CL, E, SL, C/CLK and ML Class vehicles from the model years specified in the compatibility section above.
Only the above package contents are included. Other products shown or referenced are not included. Product color may vary slightly due to lighting and display differences. Measurement tolerance is approximately ±1–3 cm.
This optical fiber audio decoding box provides a practical solution for integrating an aftermarket multimedia system with the original vehicle amplifier on compatible Mercedes-Benz models.

If there is no sound after installing the fiber optic box, check the following connections:
Check the power supply. Use a multimeter to confirm the power connection. Yellow wire: battery power 12V. Black wire: ground. The ACC power supply does not need to be connected.
Check the gateway signal. Confirm that the CAN-H and CAN-L connections are connected correctly.
Check the optical fiber communication. The optical fiber signals in the vehicle system must communicate normally. If another electrical device interrupts the optical fiber communication, the affected signal may need to be bypassed according to the vehicle's original system configuration.
