Does not Recognize Voice Commands Performed to Contact Support Center

PROCEDURE

1.	CHECK COMMUNICATION BASED VOICE RECOGNITION FUNCTION

(a) While paying attention to the condition of the spoken voice command, say "Find a gas station in New York" and check that voice recognition is operating normally.

HINT:

When the voice command is recognized, the content of the voice command is displayed in the voice recognition result display area to the right of the mic icon. (Example: When "Find a gas station in New York" is spoken, "Find a gas station in New York" is displayed in the voice recognition result display area.)
If an unnecessary word (such as "um" or "ah") is spoken before or after the recognition word, the system incorrectly recognizes the recognition word.
The system cannot recognize voice commands when multiple people are speaking simultaneously.
If the speaking speed is too fast or too slow, the recognition rate may decrease.
The system may have difficulty recognizing voice commands depending on the voice quality (such as a hoarse voice due to poor physical condition).

OK:

Voice command is recognized normally.

GPS Mark is not Displayed

CAUTION / NOTICE / HINT

NOTICE:

Depending on the parts that are replaced during vehicle inspection or maintenance, performing initialization, registration or calibration may be needed. Refer to Precaution for Audio and Visual System.

The following may occur if a radio and display receiver assembly from another vehicle is installed to this vehicle. Therefore, when replacing the radio and display receiver assembly, be sure to replace it with a new one.
- A communication malfunction DTC may be stored.
- The radio and display receiver assembly may not operate normally.

PROCEDURE

1.	CHECK CABIN

(a) Check the cabin for any objects that might interrupt radio reception and devices which use radio waves on the instrument panel. If such an object exists, remove it and check if the GPS mark reappears.

HINT:

The GPS uses extremely faint radio waves originating from satellites. If the signal is interrupted by obstructions or other radio waves, the GPS may not be able to properly receive the signal.

OK:

The GPS mark appears.

END

2.	CHECK SURROUNDINGS

(a) Check if the vehicle is in a location where GPS signal reception is poor. If the vehicle is in such a place, relocate the vehicle and check if the GPS mark reappears.

HINT:

The GPS uses 24 satellites in 6 orbits. At any point in time, 4 satellites should be able to pinpoint your vehicle. However, GPS signals may not reach the vehicle due to influence from the surroundings, vehicle direction and time. For examples, see the following illustration.

*a	Example	*b	In a tunnel
*c	In a building	*d	Under an overpass
*e	In a forest or on tree-lined path	*f	Between tall buildings
*g	Under a cliff or overhang	-	-

OK:

The GPS mark is displayed.

END (SYSTEM RETURNED TO NORMAL)

Toyota Entune App Suite Connect enables the usable content of a cellular phone to be displayed on and operated from the radio and display assembly screen.
Toyota Entune App Suite Connect 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 Entune App Suite Connect 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 Toyota Entune App Suite Connect operations, each of the applications and compatible phones, refer to http://www.toyota.com/Entune/.

*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

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.
