Hands-free system, navigation system, and terminal memory data management method

A hands-free system that stores therein terminal memory data transferred from a mobile terminal and permits access to the terminal memory data when the mobile terminal is identified through predetermined identification information, the hands-free system comprising:

• a storage portion that stores therein the terminal memory data stored in a memory of the mobile terminal in association with first identification information and second identification information;
• a receiving portion that receives first identification information and second identification information from the mobile terminal;
• a collation portion that that collates first received identification information as the first identification information that has been received and first stored identification information as the first identification information stored in the storage portion with each other and collates second received identification information as the second identification information that has been received and second stored identification information as the second identification information stored in the storage portion with each other;
• and
• a terminal memory data deletion portion that deletes the terminal memory data associated with the first stored identification information and the second stored identification information when it is determined that the first received identification information and the first stored identification information cannot be collated with each other and that the second received identification information and the second stored identification information can be collated with each other.

A terminal memory data management method in a hands-free system that stores therein terminal memory data transferred from a mobile terminal and permits access to the terminal memory data when the mobile terminal is identified through predetermined identification information, the data management method comprising:

• storing in advance into a storage portion of the hands-free system the terminal memory data stored in a memory of the mobile terminal in association with first identification information and second identification information;
• receiving first identification information and second identification information from the mobile terminal by a receiving portion of the hands-free system;
• collating first received identification information as the first identification information that has been received and first stored identification information as the first identification information stored in the storage portion with each other and collating second received identification information as the second identification information that has been received and second stored identification information as the second identification information stored in the storage portion with each other by a collation portion of the hands-free system;
• and
• deleting the terminal memory data associated with the first stored identification information and the second stored identification information when it is determined that the first received identification information and the first stored identification information cannot be collated with each other and that the second received identification information and the second stored identification information can be collated with each other, by a terminal memory data deletion portion of the hands-free system.
