Abstract: An internet based two-way data communication system for interrogating and programming the electronics of motor vehicles, with global positioning system (GPS) and real-time class 2 communication capabilities. A vehicle communications package (VCP) is located aboard each subject motor vehicle which is electronically interfaced with selected electronics of the respective motor vehicle and which provides wireless reception of GPS signals and reception and transmission of Class 2 data with respect to communication satellites, and further includes a website having a predetermined internet URL. Wireless communication between the website and the VCP is provided via a communication satellite provider having an internet interface, or a cellular telephone provider having an internet interface. The website is by a user using any computer, located anywhere and having internet access, simply by entering the website URL and the user's pre-established password/user name permissions.
