    :)

    thank god, this paired with the pac ic-av is 10 times better than alpines ipod cable, if you like scrolling through your ipod instead of the headunit...if you get this, you need to change the settings to an aux input on the headunit..use your manual.

    Great Product

    This product worked great with my alpine cda-9883, I plugged it in to the back of my unit and it fit perfectly. I would recommend this product to family and friends. I do recommend you checking to make sure you can use this product on your alpine headunit.

    Worked great, as expected

    Works without fault, highly recommend over cheap eBay knockoff. Alpine proves to be a time tested reliable company
