Thanks to the Optic fiber decoder, it is not necessary to pull cables from the trunk to the radio

Connect and install

A fiber optic connection is often an orange wire located on the back of your factory radio. The CTX-3301 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-3301 comes with an installation manual so you can complete the installation yourself. This item is only required in combination 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.
