I traded my Challenger last year and I just ran across my diablo Predator kit while packing. I'm guessing this thing is useless since the last install was on my Challenger. There goes a couple hundred bucks.
The one you have now most likely will not work on a car you get in a few years. In 11 they have a new controller and I think you'll need a new one for your new car. I think your best bet would be to get rid of it and have the new owner send it off and get it fixed. I'm sure it would be worth something and something is better than nothing.
