• wherein the controller in the navigation device is further configured to obtain an electricity amount for traveling and an electricity amount for air conditioning,
• wherein the electricity amount for traveling denotes an amount of electricity needed by the vehicle to travel from the current location to the destination,
• wherein the electricity amount for air conditioning denotes an amount of electricity needed by the air conditioner to keep functioning during travel from the current location to the destination,
• wherein the controller in the navigation device is further configured to add the electricity amount for air conditioning to the electricity amount for traveling to obtain a total amount of electricity, and
• when a remaining amount of electricity stored in the battery is less than the total amount of electricity, the controller in the navigation device operates the display to show a site where the vehicle is reachable with the remaining amount of electricity and is located between the current location and the destination, along with positional information on a charging spot around the site.
