This interface is supplied with a universal patch lead. This links the steering control interface to the steering wheel control input on the back of the new stereo.

PLEASE NOTE: This interface is only suitable for cars with original basic NTG1 radios. Cars with the upgraded COMAND APS NTG1 radio will require a different interface.
