Abstract

There are provided a CPU (11A) and an ignition key switch (17) detecting that a vehicle stops, and a transmission circuit (11C) and a transmitter (11D) for transmitting a map-image data for displaying a map image on a display (14) of a car navigation system, to a portable terminal (T) when the CPU (11A) and the ignition key switch (17) detects that the vehicle stops.

Claims

1. A device for copying map-information from a car navigation system, which has a current vehicle position detection means and a data base for accumulating map-image data, displays a current position of vehicle, and performs navigation, comprising:

vehicle stop detection means, other than the current vehicle position detection means, provided in the car navigation system for detecting a stopping of the vehicle, and

transmission means provided in the car navigation system for reading out image data of a map including a stop position of the vehicle from a map-image database when said vehicle stop detection means detects a stopping of the vehicle to transmit the image data of the map to a portable terminal, which saves the map image data transmitted from said transmission means in an internal memory, and displays a map image on a display panel based on the saved map image data;

wherein said vehicle stop detection means detects an OFF signal of an ignition key switch to detect the stopping of the vehicle.

2. The device for copy map-information from a car navigation system according to claim 1, wherein said transmission means wirelessly transmits the map-image data to the portable terminal.

3. The device for copy map-information from a car navigation system according to claim 1, wherein said vehicle stop detection means detects a vehicle speed of the vehicle to detect the stopping of the vehicle.

4. The device for copy map-information from a car navigation system according to claim 1, further comprising set means for setting a range of the map-image data transmitted from said transmission means to the portable terminal.

5. A device for copying map-information from a car navigation system which has a current vehicle position detection means and a data base for accumulating map-image data, displays a current position of vehicle, and performs navigation, comprising:

vehicle stop detection means, other than the current vehicle position detection means, provided in the car navigation system for detecting a stopping of the vehicle, and

storage means provided in the car navigation system for reading out image data of a map, including a stop position of the vehicle from the map-image database when said vehicle stop detection means detects a stopping of the vehicle, and for storing the stop position in a recording medium connectable to a portable terminal, which displays a map image on a display panel based on the stored map image data stored by said storage means in the recording medium;

wherein said vehicle stop detection means detects an OFF signal of an ignition key switch to detect the stopping of the vehicle.
