SERVICES FUNCTION

(a) "Toyota" app

"Toyota" app enables the usable content of a cellular phone to be displayed on and operated from the radio and display receiver assembly screen.
The "Toyota" app is divided into two categories, infotainment and fleet*1.
As "Bluetooth" communication is used for the communication between a cellular phone and the radio and display receiver assembly, before using the "Toyota" app function on the audio and visual system*2 or navigation system*3, the cellular phone needs to be registered to the audio and visual system*2 or navigation system*3 as a "Bluetooth" device. For details regarding the "Toyota" app operations, each of the applications and compatible phones, refer to http://www.toyota.com/audio-multimedia/.

*1: Fleet is only available on vehicles with a DCM (telematics transceiver).
*2: w/o Navigation System
*3: w/ Navigation System

(b) Destination Assist Connect (w/ Navigation System)

Downloads the user's desired destination information to the navigation function after the call center is told the destination.
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.

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 (w/ Navigation System)

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.

Refer to the navigation system for information about voice recognition.
