Abstract: A portable GPS navigation device displays map information and navigation instructions; the device (a) includes a two-way wireless transceiver operable to connect to a mobile telephone; (b) is operable to enable a user to control one or more functions of the mobile telephone and (c) includes an audio output and a microphone to enable a voice call to be made using the mobile telephone.

Abstract: A navigation device programmed with a map database and software that enables a route to be planned between two user-defined places. The device may be further programmed to be able to display on a touch sensitive display a main navigation mode screen showing a map and to allow the user to task away from that screen by touching the navigation mode screen. The device is especially advantageous for an in-car navigation device since it allows the user to easily and reliably task away, for example to the main menu, by simply touching the main navigation mode screen anywhere.

Abstract: A navigation device programmed with a map database and software that enables a route to be planned between two user-defined places. The device may also be programmed to be able to display on a touch sensitive display a main navigation mode screen showing a map and to allow a user to set a desired location as a location to be stored in device memory by touching the screen, for example at the desired location shown on the map. The navigation device is especially advantageous for an in-car navigation device since it allows the user to easily and reliably input the current location as a waypoint such as, a reference point for future navigation, even while the device is mounted in a vehicle.

Abstract: A navigation device programmed with a map database and software that enables a route to be planned between two user-defined places. The device may be further programmed to be able to display on a touch sensitive display a main navigation mode screen showing a map and to allow a user to input destination address information using a virtual keyboard whose keys are sized to allow reliable finger activation. The device is especially advantageous for an in-car navigation device since it allows the user to easily and reliably input address information, even whilst the device is mounted in a vehicle.
