CTX-3303 | Optic Fiber decoder | Mercedes E class w211 | S/SL/SLK/CLK | from 2009

The CTX-3303 Opticfiber decoder makes it possible to connect an after-market car radio in, for example, the Mercedes E-class w211 or Mercedes Clk w209 With a Bose or Harman Kardon amplifier and sound system. Thanks to the decoder, there's no need to run additional cables from the amplifier in the trunk to the radio unit.

The CTX-3303 decodes the audio that flows from the amplifier to the speakers via a fiber optic connection. This allows you to connect an Android or other aftermarket car stereo to your original speakers.

Connect and install

A fiber optic connection is often an orange wire located on the back of your factory radio. The CTX-3303 fiber optic decoder is installed on the back of the aftermarket car radio. All cables only need to be connected to the front.

Installing this product is simple, but requires some knowledge. The CTX-3303 comes with an installation manual. This item is only required in conjunction with a Bose or Harman Kardon sound system.

If you have an original CD changer from the Mercedes factory, it will no longer work after replacing the original radio. It's also not possible to connect the original radio antennas. In that case, we recommend using the free digital radio via CarPlay or Android Auto.
