Hello, I just purchased a used RBZ from Ebay from a reputable seller but it needs the security code. I know there is no way to guarantee that the radio isn't stolen but I don't think a power seller with 100% feedback would sell a stolen radio & then lie about it. He has contacted his radio guy who works in a dealership to get me the code but is there any other way? Is there a universal code? The radio is from a 2012 Caravan & I am installing it in my 2010 Ram so I know it won't recognize the serial number in my truck & it needs the unlock code. He is willing to take it back & refund me all my money plus shipping but since it's here I would rather find a way to keep it.
