I have a Pontiac Solstice which is a convertable with a manual top. I have built since managed to motorize the top and even have a remote control for the top. I also added door locks and trunk control to the remote so that I do not have to carry the manufacturer remote any more. The core of the system is an XScale Windows CE computer, and I use Phidget servo controllers for the movement of the latch, top, rear-flaps, and trunk. I also have added security switches and a GPS so I can tell when the doors open and if the car is moving, and if the car moves when the system is armed it sends me a text message with the current location, speed, and direction to assist with recovery. The system also can be told to shut down the engine so that the car cannot be driven further.
