This is my first reply on this forum..... but for what it,s worth if you find what you want to do to your car on a forum and you have a diy on it, take your lap top out with you stick some clear plastic over the keys and "voila" you have your guidance tool right beside you. I have done this many times while working on cars, or doing repairs around the house, it,s like having a teacher right beside you. Hope this helps.
