Edison,
All of the guys above have welcomed you and done their best to help you with a subject that they are not familiar with and you have been downright rude to them. They have taken time out to find what they can for you, quite frankly if you are doing some kind of research then you should know how to use a search engine, perhaps you should ask your teacher how to spell GOOGLE. The art of research is not only knowing what questions to ask, but also knowing how to ask them so that folks are willing to share their information, perhaps you should work on that.
Not only do I have this information, but also have the contact of a guy who works in the motor industry in Detroit developing such systems, he is polite, articulate and very knowlagable, however I will not put you in contact with him for fear of you being as rude to him as you are to us.
Perhaps I am being immature, but who cares, I have the info that you want, it has taken me time to accumulate it but I would have willingly shared it with anyone who had asked, NOT demanded!
Perhaps you would like to review your attitude before you leave school![](smileys/bigcry.gif)
Love and hugs 525iX
