Method for inputting destination data through a mobile terminal

1. A method of inputting destination data into a navigation system, the method comprising:

bringing a mobile terminal including a short range wireless interface into wireless communication with the navigation system via the short range wire less interface;

selecting, at the mobile terminal, at least one data record that is stored in the mobile terminal, said at least one data record including data associated with an address;

transferring the at least one data record that is selected from the mobile terminal to the navigation system via the short range wireless interface;

extracting, at the navigation system, destination data from the at least one data record that is received and using the destination data that is extracted as a destination address to determine a destination route corresponding to the destination address by the navigation system;

checking, at the navigation system, plausibility of extracted destination data using an address data base, or correcting, at the navigation system, the extracted destination data using the address database;

providing a back-channel between the mobile terminal and the navigation system; and

sending a notification back via said back-channel to the mobile terminal if the address data are not correct or if the address data are corrected.

2. The method of claim 1 , wherein the transferring the at least one data record comprises transferring a data record as the at least one data record comprising a whole entry of a selected user that is stored in a directory data base of the mobile terminal; and the method further comprises scanning, at the navigation system, the at least one data record for address data included in the whole entry of the selected user and extracting the address data that is detected by the scanning.

3. The method of claim 2 , wherein the at least one data record is encoded in an ASCII format and transferred to the navigation system.

4. The method of claim 1 , further comprising extracting, at the mobile terminal, address data included in an entry of a selected user that is stored in a directory data base of the mobile terminal and transferring the address data that is extracted within the at least one data record to the navigation system.

5. The method of claim 1 , wherein the method further comprises checking, at the navigation system, the plausibility of the destination data that is extracted by comparing the destination data that is extracted with address data stored in an address data base.

6. The method of claim 1 , further comprising correcting, at the navigation system, the destination data that is extracted with address data stored in an address data base.

7. The method of claim 5 , further comprising sending a query to a remote address data base, which is remote to the mobile terminal and the navigation system.

8. The method of claim 5 , further comprising sending a notification via the short range wireless interface back to the mobile terminal, if the destination data that is extracted is not correct based on the checking of the plausibility of the destination data.

9. A mobile terminal, comprising:

a short range wireless interface unit which communicates wirelessly with a navigation system;

a storage unit which stores data associated with at least one address; and

a control unit which selects at least one data record including data associated with an address and wirelessly transfers the at least data record that is selected to the navigation system via the short range wireless interface unit;

wherein the mobile terminal receives a notification from the navigation system via a back-channel provided between the mobile terminal and the navigation system if the navigation system determines that the address data are not correct or if the address data has been corrected by the navigation system.

10. A system comprising:

a navigation system; and

a mobile terminal including a short range wireless interface unit which communicates wirelessly with the navigation system, a storage unit which stores data associated with at least one address, and a control unit which selects at least one data record associated with an address and wirelessly transfers the at least one data record that is selected to the navigation system via the short range wireless interface unit,

wherein the navigation system extracts destination data from the at least one data record that is received and uses the destination data that is extracted as a destination address to determine a destination route corresponding to the destination address; and

wherein the navigation system checks plausibility using an address data base or the navigation system corrects the extracted destination data using the address data base,

wherein the navigation system sends a notification back to the mobile terminal via back-channel provided between the mobile terminal and the navigation system if the address data are not correct or if the address data are corrected.
