An apparatus and methods for enhanced data communications and control between a vehicle and a remote data communications terminal are disclosed. The apparatus preferably includes a first protocol converter adapted to be positioned in communication with at least one electronic subsystem of the vehicle, a first transceiver, a first requestor, and a first buffer. The apparatus also preferably includes a second transceiver, a second protocol converter, a second requestor, and a second buffer. The first protocol converter converts data of a vehicle communication protocol to data of an over-the-air communication protocol. After the first requestor opens a window in an over-the-air communication channel between the vehicle and the remote data communications terminal, the first transceiver in the vehicle wirelessly transmits data over-the-air from the vehicle to the second transceiver in the remote data communications terminal preferably not using the over the air communication protocol. When the vehicle is not transmitting data via the first transceiver, data received from the remote data communication terminal and stored in the first buffer is then transferred to the at least one electronic subsystem of the vehicle. Also, when the remote data communication terminal is not transmitting data via the second transceiver, data received from the vehicle and stored in the second buffer is then transferred to other portions of the remote data communication terminal.
