Abstract

A navigational device, where an input destination is first clearly and unambiguously determined on the basis of a data record stored in the navigational device, and, only then, is this destination transmitted to a central processing unit for purposes of route determination.

Claims

1. A navigational device comprising:

a control unit;

a memory unit having stored name designations for determining a stored name designation from an input using the control unit to establish a destination;

an interface for transmitting destination data assigned to the determined, stored name designation; and

a central processing unit for receiving the destination data from the interface and for calculating a route to the destination.

2. The navigational device according to claim 1, further comprising a data medium drive for accommodating a data medium having stored name data.

3. The navigational device according to claim 1, wherein one of (a) name designations and (b) a group of name designations are selected and transmitted via an interface to the navigational device.

4. The navigational device according to claim 3, wherein the interface is a radio interface, to at least one of a cellular radio network and a data network.

5. The navigational device according to claim 1, wherein the name designations include at least one of (a) location names, (b) street names and (c) names of institutions.

6. The navigational device according to claim 1, further comprising an encoding unit for at least one of an encoded transmission and a compressed transmission of destination data to the central processing unit.

7. A method for inputting and transmitting a destination, the method comprising:

inputting data for establishing a destination into a navigational device;

from the input data, transmitting specific destination data to a central processing unit; and

matching the input data to a data record of the navigational device prior to transmission in such a way that the transmitted destination data in the central processing unit allows a clear, unambiguous assignment of the transmitted destination data to a position in a road network.

8. The method according to claim 7, wherein the data is transmitted via a radio communications link to the central processing unit.

9. The method according to claim 8, further comprising first establishing the radio communications link from the link to the central processing unit when a determination of the destination data is concluded.

10. The method according to claim 8, further comprising transmitting the data record used for a matching operation via the radio communications link to the navigational device.

11. The method according to claim 10, wherein the radio communications link includes a data network.

12. The method according to claim 7, further comprising assigning the data record used for a matching operation to a user of the navigational device.
