I currently have a Viper alarm on my truck with remote start, tilt sensor, glass and shock sensors, hood an trunk, motion detection, and the list goes on. It was about $600 alone with all the add ons. So to put that in a temperamental beast like the 7 series, I can only imagine the kind of work involved. props to you and I can't wait to see it when it's all done.
