Patent ID: 8099108

Claim:
A method comprising: estimating a current geographic position of a mobile terminal including a communication module and a display screen; determining if the estimated current position of the mobile terminal is within a boundary of geographic map information stored in the mobile terminal, the geographic map information defining geographic features within a first geographic area; in response to determining that the estimated current position of the mobile terminal is within the boundary of the stored geographic map information, displaying the map including the current position of the mobile terminal on the display; in response to determining that the estimated current position of the mobile terminal is not within the boundary of the stored geographic map information, providing additional geographic map information to the mobile terminal using the communication module, the additional geographic map information defining geographic features within a second geographic area that includes the estimated current position of the mobile terminal; and determining a current scale for the display screen to display a map by estimating a current speed of the mobile terminal and automatically selecting a display scale in response to the current speed of the mobile terminal, wherein selecting the display scale comprises selecting a relatively larger scale if the speed of the mobile terminal is higher and selecting a smaller scale if the speed of the mobile terminal is smaller.
