I have a climate control screen in my rx300. It is basically a lcd, not a nice pc type though more of a digital alarm clock type. Well, what I am trying to do is to display that info in a pc program but I have no idea how to get it. Is there something I could hook up to the harness and get the data from it? I am fairly good at programming in C++, and VB, but not too familiar with car stuff so any help would be greatly appreciated.
No announcement yet.
