1. A system mounted in a vehicle for enabling a user to control a component of the vehicle, said system comprising:
- a computer having a CPU;
application software installed in said computer;
said software comprising code executable by said CPU for controlling the component by said computer generating a command sendable to the component;
a user interface connected to said computer for generating an input indicative of a function of the component in response to actuation by the user, said application software receiving said input; and
