If it is on the radio harness can anyone supply me with a full wiring diagram to include steering control wires? Thanks Alot!!!!!!!

  • Reply ModifiedLife January 12, 2012 at 11:29 pm

    David, if you’re installing an aftermarket radio into your 2001 BMW 325xi and want to retain your steering wheel controls it is possible but it depends on the manufacturer of your aftermarket radio:

    Steering Wheel Control Adapter for Alpine Radio
    Steering Wheel Control Adapter for Blaupunkt Radio
    Steering Wheel Control Adapter for Clarion Radio
    Steering Wheel Control Adapter for Eclipse Radio
    Steering Wheel Control Adapter for JVC Radio
    Steering Wheel Control Adapter for Kenwood Radio
    Steering Wheel Control Adapter for Pioneer Radio
    Steering Wheel Control Adapter for Sony Radio
    Steering Wheel Control Adapter for Valor Radio

    If you have never installed car audio before, we advise you to take your car to an experienced mobile audio installer. Hope this helps. Good luck with your 2001 BMW 325xi stereo installation.
