Abstract
In a vehicle-installed AV device, the power is supplied to various sections of the vehicle-installed AV device via a key switch from a battery of a vehicle. The vehicle-installed AV device is provided with: a predicting/detecting section for detecting a running state of the vehicle to predict an engine stop; a flash memory and a main memory for storing operation data of the vehicle-installed AV device; and a CPU for controlling the flash memory and the main memory. When the predicting/detecting section predicts the engine stop, the operation data stored in the main memory is written into the flash memory.
