Methods and apparatus are described for displaying information corresponding to a current vehicle position on a display of a vehicle navigation system. After the current vehicle position is determined by a separate process, the system determines the road on which the vehicle is currently located. The system then refers to a map database to construct a current road database corresponding to the current road. A current road segment corresponding to the current vehicle position is then determined. The system then refers to the current road database to determine a first geographical location based on the current vehicle road segment. The system then displays a text representation of the current vehicle position relative to the first geographical location.

Method and apparatus for displaying current vehicle position

A method for transmitting data from a navigation system to a vehicle controller in a vehicle having a plurality of systems controlled by the vehicle controller is described. The plurality of systems includes a user interface and the navigation system. A request is received from the vehicle controller for interface data of a particular data type to be presented in the user interface. A first transmission protocol is selected from a plurality of transmission protocols for transmitting the interface data to the vehicle controller. The first transmission protocol is selected based, at least in part, on the data type of the interface data. The interface data are then transmitted to the vehicle controller according to the first transmission protocol.

Communication protocol for a vehicle navigation system

A method and apparatus for selecting a destination in a vehicle navigation system are described. The vehicle navigation system includes a display and a selection control. A first destination is selected from a primary list of destinations in response to a selection signal generated by the selection control. The first destination is placed on a secondary list of destinations in response to its selection. The secondary list includes previously selected destinations from the primary list. For subsequent destination selections, the primary and secondary lists are presented on the display thereby facilitating selection of destinations from both the primary and secondary lists. A feature by which the system may search for a destination across categories is also described.
