2. Description of the Related Art In order to enjoy a drive, it is common practice to play back favorite music using an on-vehicle audio device. In many conventional methods, a recording medium such as a cassette tape or a CD that is brought into a vehicle is mounted on an in-vehicle audio device and the contents are reproduced. Therefore, the user prepares a recording medium that suits his / her preference in advance,
They must be brought into the car.

On the other hand, there has been proposed a method in which music information is obtained from a predetermined information center to a vehicle-mounted audio device via a wireless line without a user bringing in a recording medium. For example, JP-A-11-30986 discloses a "music data acquisition system for vehicles". In this system, data relating to music playback conditions of the in-vehicle audio device is transmitted to an information center (for example, an existing system such as a VICS (Vehicle Information Communication System)), and the information center generates data adapted to the playback condition data. This is transmitted to the vehicle side and reproduced on the vehicle side. In this case, for example, the quietness in the vehicle is set as a reproduction condition, and a sound of a level that cannot be heard even when reproduced at the information center is deleted at the time of transmission.

[0004]

In the above-mentioned conventional method, in the case of a cassette tape, it takes time to find a desired music piece, and it is difficult to quickly select a music piece. Also, in the case of a CD, there is a problem that sound skipping occurs when traveling on a rough road and stable reproduction is difficult. Also,
The method of distributing music using the VICS system solves the above-mentioned problems of cassette tapes and CDs. However, the VICS system is limited in its application area and cannot be used by any user anywhere.

Therefore, an object of the present invention is to provide a portable telephone or a PH
