Mercedes-Benz B200 Car Stereo Optical Fiber Decoder Box GPS

Introducing the Mercedes-Benz B200 Car Stereo Optical Fiber Decoder Box GPS by EzoneTronics. This compact optical-fiber decoder preserves your car’s Bose or Harman Kardon sound system when integrating with factory fiber-optic interfaces. By decoding the optical signal, it keeps the original amplifier active, delivering clear, balanced sound without needing to replace components or reroute long cables. Designed specifically for Mercedes-Benz B200, this decoder box maintains premium audio fidelity while simplifying installation.

Built for reliable performance, the decoder features gold-plated copper wiring inside a durable plastic enclosure and operates at 6 V. Its compact dimensions—7.4 x 5.5 x 2.5 cm—and light weight (0.82) make it easy to position in the engine bay or trunk area. The device connects to the car’s fiber-optic interface and to the factory B+ GND and audio lines, enabling seamless integration with the existing system and preserving the original sound stage.

Important installation note: The fiber-optic box installation can vary by vehicle model. If you’re not sure your vehicle will be installed, take a photo of your radio and let us know. No need to run 6 meter long cables from front to rear — your car’s trunk wiring is simplified because all necessary connections are made at the front. It’s designed to be plug-and-play and easy to install.
