Abstract:
1. A motor vehicle telephone system that is operative in both a normal motor vehicle power-on mode and in a stand-by mode when the vehicle is turned off, the telephone system comprising: a transmit/receive unit that transmits data over a wireless communication channel, and receives data over the wireless communication channel and provides a received signal indicative thereof; a control unit that selectively communicates with the transmit/receive unit; a first memory device; a computing device that receives the received signal and automatically stores the received signal data in the first memory device when the telephone system is in the stand-by mode; and a switch that selectively controls communications of the control unit with the transmit/receive unit, where the switch prevents transmission of an outgoing telephone call originated by the control unit to the transmit/receive unit when the telephone system is in the stand-by mode, and where the transmit/receive unit automatically communicates with an external service when the telephone system is in the stand-by mode and stores data received from the external service in the first memory device.
