Porsche Boxster, Cayman and 911 fibre optic BOSE amplifier retention interface 23-240

MOST fibre optic interface designed to retain the use of the original Bose fibre optic amplifier in Porsche Boxster, Cayman, 911 and Cayenne cars fitted with original CDR23 CDR24  PCM2, PCM2.1 and PCM3 head units to allow the fitting of an aftermarket radio upgrade.

The interface connects at the back of the radio, it takes the phono audio output from the new radio and converts it to a digital signal that works with the original Bose amplifier. Note, the front to rear fade feature will be lost.

Vehicle compatibility:

This interface is to retain audio with the Bose amplifier only, it does not generate an ignition power supply or retain the use of the steering wheel controls.
