The present invention provides systems and methods for reducing the `cold
start` TTFF of navigation receivers. The systems and methods receive
geographical information from a user, such as the nearest city, state or
country, and use this geographical information to approximate the
position of the receiver. The systems and methods then make use of the
approximate position to reduce the `cold start` TTFF. In an embodiment,
the approximate position of the receiver is determined from a co-ordinate
database in the receiver based on the geographical information provided
by the user. In another embodiment, a user provides geographical
information to the receiver through a displayed map with several stages
of zooming capability.
