Abstract: A hands-free apparatus includes a memory, and a hardware processor coupled to the memory. The hardware processor is configured to: perform a hands-free connection process of connecting to a mobile phone by using a hands-free communication protocol for performing a hands-free phone conversation; perform a first data transfer process of making a first connection with the mobile phone by using a data transfer protocol for transferring phone data related to phone, and causing the phone data to be automatically or manually transferred from the mobile phone; and depending on a status of a different data transfer process than the first data transfer process, perform transfer control related to transfer by at least one of the first data transfer process and the different data transfer process.
