Hey! I bought a 8.4 uconnect radio to upgrade the 5.0 uconnect that came in my 2015 challenger off of eBay. When I installed it in the car it ask for a 4 digit code. I went to the dealership to get it programmed and they told me they couldn't without the vin number of the car that the 8.4 came out of, so I emailed the seller on eBay and asked him for the vin and he said he didn't have it. Is there anything else I can do to get the code?
