3 SERIES CD RADIO STEREO HEADUNIT ISO WIRING HARNESS LEAD ADAPTOR CT20BM03

This adaptor will enable you to replace your factory fitted head unit with an aftermarket model.

It converts the cars power and speaker plug into a standard ISO connection, suitable for all aftermarket head units (Alpine, Clarion, JVC, Kenwood, Pioneer, Sony etc).

You simply plug one end of the adaptor into your cars original wiring harness, and the other end into the new head unit. No cutting of wires is necessary.

 With vehicles that have the new Fakra or Quadlock connection there is no ignition switched 12v supply. This is usually required for aftermarket head units, and they won't power up with out this being connected
