Abstract: A communication system for vehicle management includes a vehicle, a vehicle management system disposed in the vehicle outputting first data to control substantially a function of the vehicle and recording second data substantially analogous to an operating parameter of the vehicle, a base station substantially remote from the vehicle and having a second transceiver, a first transceiver disposed in the vehicle and connected communicably to the vehicle management system to receive third data from the second transceiver and send the second data to the second transceiver, the third data updating the vehicle management system.

Abstract: A audio communication system for a vehicle includes a primary audio source producing a primary audio signal, a secondary audio source producing a secondary audio signal, a speaker, a vehicle ignition switch having an on position and an off position, and a relay. The primary and secondary audio sources may be alternatively transmissibly connected to the speaker by the relay. The relay receives the primary audio signal and transmits substantially the primary audio signal to the speaker when the vehicle ignition switch is in the on position and the secondary audio signal is not present. The relay receives the primary and secondary audio signals and transmits substantially the secondary audio signal to the speaker when the vehicle ignition switch is in the on position. The relay receives the secondary audio signal and transmits substantially the secondary audio signal to the speaker for a predetermined period of time after the vehicle ignition switch has been switched from the on position to the off position.
