Hello guys, I'm having issues with upgrading my radio. I have the 5 inch radio and i wanted to put the 8.4 in my 2015 Chrysler 200. my understanding is it should work just fine getting one from another vehicle and that's what I did. I got one from a 2017 jeep grand cherokee. I plugged it in back up camera works climate controls work and the anti theft code needed popped up and I thought no problem I have the code but I typed it in and it said it was wrong. so I called the dealership told them the S/N number and VIN to the jeep. They confirmed I had the right code but still wasn't working. any suggestions on what to try? is the 2017 to new for my car?
