Prautogy's iPhone application "Halo" can control everything from starting your car, unlocking the doors, honking the horn, and turning on the headlights. The application provides feedback to show that headlights are on. From the iPhone screen you can control the hydraulics of the car. The application uses a blue tooth interface and is modular, so that you can choose which modules to use.
