ISO radio adapter harness for Mercedes cars with original quadlock radios.

This adapter cable is designed to adapt from the original ISO wiring in the vehicle to standard aftermarket ISO wiring to allow the fitting of a new radio upgrade.

This lead has a built in CANbus interface which provides an ignition feed to the new stereo so that it turns on and off with the key. Additionally it will provide an illumination signal to dim the radio display when the headlights are on. The CANbus interface is built into the adapter cable for a plug and play installation.

NOTE: This adapter cable does not support steering wheel control functions. Not suitable for cars with a fibre optic amplifier (BOSE, Harman Kardon, or BMW TOP Hi-Fi) or Mercedes with Audio 5 or 10 head units.
