Aftermarket car radio replacement quadlock to ISO adapter cable suitable for multiple Audi vehicles with amplified rear speakers built between 2005 and 2013.

Allows an aftermarket radio to be fitted without cutting the original wiring.

This cable features a CANBUS interface which provides a switched 12v feed for the radio to turn on and off with the key making this interface plug and play. Additionally this adapter includes an interface for the amplified rear speakers found in most Audi cars that allows the volume levels to be adjusted on the rear speakers to create a balanced sound around the car and avoid interference or external noise being heard.

This interface does not retain steering wheel controls.
