Abstract

A navigation device is disclosed. In at least one embodiment, the navigation device includes a storage device to store map information;

a processor to determine a route of travel based upon a current position of the navigation device and an input or selected destination position; and
a display to display the current position on the map information corresponding to the determined route of travel, the display displaying zoomed-in display of the map information upon the processor determining that a speed of a vehicle, in which the navigation device is located, is below a threshold speed.

Claims

1. A navigation device, comprising:

a storage device to store map information;

a processor to determine a route of travel based upon a current position of the navigation device and an input or selected destination position; and

a display to display the current position on the map information corresponding to the determined route of travel, the display displaying zoomed-in display of the map information upon the processor determining that a speed of a vehicle, in which the navigation device is located, is below a threshold speed.

2. The navigation device of claim 1, wherein the zoomed-in display of the map information relatively increases as the speed of the vehicle in which the navigation device is located relatively decreases.

3. The navigation device of claim 1, wherein the zoomed-in display of the map information progressively increases as threshold speeds are reached.

4. The navigation device of claim 1, wherein the display returns to a normal display of the current position on the map information corresponding to the determined route of travel, upon the speed of the vehicle reaching the threshold.

5. A method, comprising:

storing map information in a storage device of a navigation device;

determining a route of travel based upon a current position of the navigation device and an input or selected destination position; and

displaying, on a display of the navigation device, the current position on the map information corresponding to the determined route of travel, the displaying including a zoomed-in display of the map information upon determining that a speed of a vehicle, in which the navigation device is located, is below a threshold speed.

6. The method of claim 5, wherein the zoomed-in display of the map information relatively increases as the speed of the vehicle in which the navigation device is located relatively decreases.

7. The method of claim 5, wherein the zoomed-in display of the map information progressively increases as threshold speeds are reached.

8. The method of claim 5, wherein the displaying returns to a normal display of the current position on the map information corresponding to the determined route of travel, upon the speed of the vehicle reaching the threshold.
