Methods and systems are provided for vehicle data communications. The system includes a vehicle communication component configured to receive data, encode the data to be transmitted, and transmit the encoded data wirelessly. A data delivery unit is configured to receive the encoded data, decode the encoded data, and present data in at least one format. A wired communication link couples the vehicle communication component and the data delivery unit. The wired communication link is configured to relay decoding information from the vehicle communication component to the data delivery unit such that the data delivery unit may decode the encoded data.
