This adaptor will enable you to replace your factory fitted stereo with an aftermarket unit. It converts the cars original wiring plug into a standard ISO connection for all new stereos. You simply plug one end of the adaptor into your cars original wiring harness, and the other end into the new stereo, so no cutting of wires is necessary. Fits all Mk2.5 2000>2005 and all Mk3 models 2005>2008
Please Note: This is not suitable for any cars fitted with a Bose stereo system.
