Abstract: A non-contact power supply system supplies electric power in a non-contact manner from a power transmission device to a vehicle. The power transmission device includes an impedance adjusting unit configured to adjust an impedance between a power supply unit and a power transmission unit. A vehicle ECU assists an alignment between the power transmission unit and the power receiving unit in the parking operation based on a power transmission efficiency between the power transmission unit and the power receiving unit. A power transmission ECU, at the time of the alignment in the parking operation, controls the impedance adjusting unit based on a distance between the power transmission unit and the power receiving unit in a vertical direction (vehicle height). Accordingly, lowering of the power transmission efficiency caused by a change in an impedance along with a change in the vehicle height can be suppressed.

The information center prepares a guidance data of recommended route using latest road data held in the information center, and transmits the data to the navigation apparatus. When the information center transmits the guidance data, the information center selects the type of data of the road links along the recommended route, in the guidance data, by comparing the version data received from the navigation apparatus and the version data of each road link along the recommended route.
