Abstract
A navigation device at least includes a CPU and a detector generating a detection signal for determining whether a main device is used inside a vehicle or not. If determining, based on the detection signal from the detector, that the main device is used inside the vehicle, the CPU operates in on-vehicle mode to carry out first navigation (present position estimation and route search) suitable for use in the vehicle. Otherwise, the CPU operates in off-vehicle mode to carry out second navigation (present position estimation and route search) suitable for use outside of the vehicle. Thus, the navigation device can automatically switch its operation mode between on-vehicle mode and off-vehicle mode.
