Mercedes Benz Porsche Aftermarket Head Unit Extension Cord for fiber optic most amplifier

MOST Mercedes Benz and Porsche come with factory fiber optics audio system. The audio signal is not the same as the aftermarket head unit. In this case, there will be no audio at all after installing the aftermarket navigation head unit. And you need this product.
One end connects to the aftermarket head unit, and another end connects to the amplifier plugs in the trunk.

This product includes a six meters audio/power cable and a six meters FM/AM antenna adapter cable. It allows you to bypass the factory Harmon Kardon audio fiber optic system or BOSE audio fiber optic system when installing the aftermarket navigation head units from www.sigmacarstereo.com, it may also work with aftermarket head units from other manufacturers, please contact us if you are not sure about the compatibility before place the order.

 Attention:
1. There will be only four car speakers working after bypassing the factory fiber optics audio system.
2. It is plug-and-play for Mercedes-Benz/Porsche with Harmon Kardon fiber optic audio system, they have the same connectors. But if your car has BOSE fiber optic audio system, then the audio connectors are not the same, you need to splice wires. Please contact us before placing the order if your car has BOSE fiber optic audio system.
