1. A method of operating an audio, video, navigation (AVN), the method comprising:
- determining whether a vehicle speaker and a vehicle microphone connected to the AVN are operational when a car accident occurs;
releasing pairing with a paired terminal and performing role change of changing the terminal to a hands-free unit (HF) when at least one of the vehicle speaker and the vehicle microphone is not operational; and
performing, by the AVN, voice call using a speaker and microphone of the terminal after the role change is completed,wherein the role change is an operation of exchanging functions of the AVN and the terminal with each other such that the AVN operates as an audio gateway (AG) and the terminal operates as the HF.
