PROBLEM TO BE SOLVED: To provide a radio LAN system for sharing data both in a domestic area and in a vehicle. SOLUTION: In a radio LAN control unit 1, a shared holder of hard disk of personal computers P1, P2 is certified when radio LAN connection with a radio router 21 is established (steps S1-S3). If there is data in the shared holder, the radio LAN control unit 1 receives the data on condition that power is fed to the navigation control unit 3 and the hard disk 4 (steps S4-S8). The received data is stored in the hard disk 4 by the navigation control unit 3 (step S9). When all data of the shared file is received, the radio LAN control unit 1 sets the power supply of the navigation control unit 3 and the hard disk 4 to the same condition as before receiving the data (steps S10-S12).
