Sooo, When I got my 2012 Leaf, the dealer set up the whole carwings app and account for me. It was awesome. For car #2, I was in a bit of a rush, and they didn't set it up. I have had this car for nearly 3 years and have NEVER used carwings. Is it too late? Does it cost money (I had heard something about this, and can't quite discern this from the other forum posts I looked at)? Can I do it, or do I have to have the dealer set it up?
