I have the app and i love it. start my truck from where ever i am and lock or unlock it too. its not as intrusive as some think. the app can not track you. onstar can only track you with your expressed permeation. and if you have onstar and the government wants to know where you are the have to get a subpoena to access your tracker same as if they want to track of bug your cell phone unless you are suspected of terrorist activity them your free game per the patriot act. get the app you will love it i use it all the time.
