The C3 system gives a car owner a link to their vehicle from anywhere they get cell phone reception, using either java-based software or a WAP interface. Among its many features, C3 can unlock and start your car, track it via GPS, alert you to unwanted car movement, and arm your car alarm. Paranoid parents can also set a "speed alert" that will message them when the car exceeds a certain preset speed.
Our picture shows the java interface on a Nokia, but Autopage assures us that the WAP interface gives C3 iPhone compatibility as well. The price for all of this control starts at $149 for a year of "basic usage" which offers the full feature set, but is limited to 200 uses per month - unlimited use costs $249 per year. The system itself is installed as an aftermarket product and will cost around $1000 when it is released in two weeks. [C3]
