A motor vehicle entertainment system includes a radio receiver and a
control unit. The control unit receives a first status signal indicative
of whether or not a motor vehicle door has been unlocked and initiates
the application of power to the radio receiver upon the first status
signal indicating that the door has been unlocked. Upon the application
of power to the radio receiver, the radio receiver scans through a
selected frequency spectrum to identify valid frequencies and their
associated broadcast identifying information and stores a list of the
valid frequencies and their associated broadcast identifying information
in a memory device associated with the radio receiver. The radio receiver
acquires and records information on a plurality of transmitters initially
in a standby mode before it switches over to an operating mode. The radio
receiver has a device for receiving an ON command from the user and
switches from the standby mode to the operating mode when the ON command
is received. The radio receiver may begin to operate before the ON
command is input by the user, and independently of this input. If the
radio receiver begins to operate in sufficient time before input of the
ON command, then collection of transmitter information by the radio
receiver may already be complete before the user inputs the ON command,
which is typically indicative of the desire of the user to listen to an
audio signal.
