  • Question: 05 January 2022
    Car: Vauxhall Corsa - 2009>

    What is the correct ISO harness for Pioneer DMH-A240BT. Also can this unit be connected without the steering wheel controls & head unit function as normal? Thanks


    No, you need a CAN-BUS loom or you will have issues with the vehicle. Please confirm year and we will advise accordingly.
