1. A vehicle application wireless remote control communications system comprising:

  • a remote unit comprising a receiver and transmission circuitry, for carrying by a user, the remote unit being operative to exchange data in a plurality of modulation modes, the remote unit further being operative to contain and transmit a representation of a user-selected vehicle application function, the remote unit further being operative to receive representations of vehicle-selected vehicle application functions;

    a mobile unit comprising a receiver and transmission circuitry, for mounting on a vehicle and exchanging data with the remote unit, and operative to transmit and receive data in the plurality of modulation modes, the mobile unit further being operative to contain and transmit one or more of the representations of the vehicle-selected vehicle application functions;

    a means for the communications system to select a selected modulation mode from among the plurality of modulation modes for exchange of data between said remote and mobile units; and

    an interface from the mobile unit to a vehicle application controller so that the user-selected vehicle application function is implemented whereby the representation of the user-selected vehicle application function is transmitted from said remote unit to said mobile unit by said selected modulation mode, wherein, in response to receiving at the mobile unit the representation of the user-selected vehicle application function transmitted by the selected modulation mode from the remote unit, a signal corresponding to the user-selected vehicle application function is sent from the mobile unit via the interface to the vehicle application controller for execution.
