Map transmission for in-vehicle navigation system with dynamic scale/detail adjustment

A method of providing map information of varying resolution to a navigation device comprising the steps of:

• generating position information of a navigation device,
• transmitting said position information of said navigation device to a base station,
• transmitting map information of varying resolution related to said position information of said navigation device from said base station to said navigation device,
• receiving said map information at said navigation device, and displaying at said navigation device said map information related to said position information of said navigation device such that a visual representation of said map information related to said position information of said navigation device is produced.

An apparatus for providing map information of varying resolution to a navigation device comprising:

• a base station adapted to transmit map information of varying resolution therefrom,
• a navigation device communicatively coupled to said base station, said navigation device further comprising:
• a receiver adapted to receive said map information of varying resolution transmitted from said base station, and
• a display adapted to display said map information of varying resolution, and
• a position determining system coupled to said navigation device, said position determining system generating position information of said navigation device, said position determining system communicatively coupled to said base station, said position determining system adapted to transmit said position information of said navigation device to said base station,
• wherein said map information of varying resolution transmitted from said base station is related to said generated position information of said navigation device transmitted to said base station from said position determining system.
