Abstract

An onboard apparatus uses two modes to transfer audio data from a mobile phone. A first mode transfers and outputs audio data stored in the mobile phone. The first mode communicates control data according to a control data transfer protocol and transfers and outputs audio data according to an audio data transfer protocol. The second mode permits the mobile phone to successively buffer audio data stored in a server on a communication network and to concurrently transfer and output the buffered data. The second mode replaces the control data transfer protocol with a specific data communication protocol. The second mode communicates control data according to the specific data communication protocol and transfers and outputs audio data according to the audio data transfer protocol. The second mode can communicate any commands and data using the specific data communication protocol regardless of commands specified in the control data transfer protocol.
