In an automobile, communications to and from the automobile are in the form of
messages. Such messages are referred to as "electronic car-mail" or "C-mail" messages
as each message has a destination or origination address which includes an identifier,
e.g., a vehicle identification number (VIN), identifying the automobile. The messages
may be delivered to the automobile from a remote server through a communications
network, e.g., the Internet. One such message may contain a recall notice to the
automobile. Another message may contain just-in-time map information for navigation,
depending on the current location of the automobile. Yet another message may contain
advertising information concerning selected entities, e.g., restaurants, gas stations,
department stores, etc., also depending on the current location of the automobile.
The messages transmitted from the automobile to the remote server may contain,
e.g., GPS information identifying the location of the automobile, dynamic data
furnished by sensors in the automobile for analysis, an odometer reading and a
speedometer reading for records, etc.
