  • Stores the information downloaded in the navigation function so the information can be reused as required.
  • Destination Assist Connect is an in-vehicle service that allows subscribers to request directions to any location. Subscribers are connected to an agent through the Destination Assist button and may ask the agent to download the location of any destination to the navigation function in the vehicle. Agents are able to locate specific Points Of Interest (POI's) by search terms, locate specific addresses, or provide Zagat-rated restaurants as premium POI's. Agents are able to search for POI's using the distance from the vehicle, from a city, or from another POI. The navigation function can store up to 5 POI's at a time, which can be added to the device queue as the first or last entry, or as a replacement for all entries.

(c) Dynamic Navigation

  • Dynamic navigation searches the server for the latest map data and traffic information, etc., and depending on the latest traffic status and other data, optimizes the route and updates the map.
  • Dynamic navigation requires a contract, and a full update of the map database in the navigation ECU should be performed every 3 years.

(d) Dynamic Voice Recognition

By performing the voice recognition process with the server, natural talk input and other interactive voice operations besides the specified commands can be performed. In addition, by storing all of the user's utterances, the server will learn, and be able to perform voice recognition with greater accuracy.
