Abstract
An object of the present invention is to provide a navigation device that can automatically open/close an electric garage door by remote control without manual operation and that can prevent erroneous opening/closing of the electric garage door. A navigation device can be connected to a wireless garage door opener transmitter . The navigation device transmits an open signal to the wireless garage door opener transmitter when a vehicle position calculated by a GPS receiver and an orientation detected by a gyro sensor are within a predetermined range that respectively includes a preset electric garage door open instruction position and orientation, and a vehicle speed detected by a vehicle speed sensor is no greater than a predetermined value. Thus, erroneous opening of the electric garage door when the vehicle approaches the electric garage with an object other than entering the electric garage can be prevented.
