Communication device for updating current navigation contents

Abstract

The invention provides a communication device for updating current navigation contents stored in a navigation device. The communication device comprises a retrieving element for retrieving information indicating current navigation contents from the navigation device, a transmitter for transmitting the information indicating the current navigation contents to a remote network device via a communication network, a receiver for receiving updated navigation contents from the remote communication device and a processor for displaying information relating to the updated navigation contents or for installing the updated navigation contents on the navigation device.

1 . A communication device for updating current navigation contents stored in a navigation device, the communication device comprising: 
 a retrieving element for retrieving information indicating current navigation contents from the navigation device;    a transmitter for transmitting the information indicating the current navigation contents to a remote network device via a communication network;    a receiver for receiving updated navigation contents from the remote communication device; and    a processor for displaying information relating to the updated navigation contents or for installing the updated navigation contents on the navigation device.    
     
     
         2 . The communication device according to  claim 1 , the retrieving element being further configured to retrieve information indicating device identification or user identification from the navigation device, the transmitter being further configured to transmit the device of user identification to the remote communication device.  
     
     
         3 . The communication device according to  claim 1 , the transmitter being further configured to transmit the information indicating the current navigation contents as meta data or as a table of contents file.  
     
     
         4 . The communication device according to  claim 1 , the retrieving element being configured to connect to the navigation device for obtaining current navigation contents from the navigation device.  
     
     
         5 . A method for updating current navigation contents stored in a navigation device, the method comprising: 
 retrieving information indicating current navigation contents from the navigation device;    transmitting the information indicating the current navigation contents to a remote network device via a communication network;    receiving updated navigation contents from the remote communication device; and    displaying information relating to the updated navigation contents or installing the updated navigation contents on the navigation device.    
     
     
         6 . The method according to  claim 5 , further comprising retrieving information indicating device identification or user identification from the navigation device or transmitting the device of user identification to the remote communication device.  
     
     
         7 . The method according to  claim 5 , comprising transmitting the information indicating the current navigation contents as meta data or as a table of contents file.  
     
     
         8 . The method according to  claim 5 , comprising verifying the entitlement of a user associated with the navigation device or verifying the entitlement of the navigation device for obtaining certain updated navigation contents.  
     
     
         9 . The method according to  claim 5 , the navigation contents or the updated navigation contents comprising information indicating routing information or updated firmware or map information.  
     
     
         10 . The method according to  claim 5 , the information indicating the updated navigation contents comprising priority information indicating that a certain navigation content has a higher priority than another navigation content.  
     
     
         11 . A computer program for performing the method according to  claim 5  when the computer program runs on a computer.
