Land Rover Discovery: Description - Incontrol Touch Audio Systems

The Audio Head Unit (AHU) is located in the center of the instrument panel, below the Touch Screen (TS).

Level C AHUs support voice control and navigation. Level B does not support voice control or navigation.

For additional information, refer to: Audio System (415-01, Description and Operation).

The AHU contains the recognizer, dialogue and Text-to-Speech (TTS) parts of the voice engine used to determine what the user wants to control by voice. Additional voice control software is located on the SD memory card installed in the portable audio interface panel.

Portable Audio Interface Panel

Portable Audio Interface Panel

Voice control software is stored on the SD memory card in addition to the software contained within the AHU. Navigation and telephone system software is also stored on the SD memory card.

Vehicles with a Level C AHU have a portable audio interface panel which includes an SD memory card slot for navigation system, voice control and telephone software.

For additional information, refer to: Navigation System (415-01 Information and Entertainment System, Description and Operation).

NOTE:

The SD memory card must not be removed or the files modified. If the card is removed, the navigation, voice control and telephone will be inoperable. The SD memory card slot cannot be used for media files. Installation of any external content or modification of the files on the SD memory card can corrupt the SD memory card and cause voice control, telephone and navigation systems to be inoperable.

Removal and re-installation of the SD memory card when the ignition is on (power mode 0) will cause voice control, telephone and navigation systems to be inoperable. To re-initialise the SD memory card, switch the ignition to 'off' and lock and arm the vehicle (power mode 6). Install the SD memory card in the slot in the portable audio interface panel and switch the ignition to 'on' (power mode 6). The card will be detected and voice control, telephone and navigation will operate correctly.

A microphone is located in the front overhead console and is hardwired to the AHU. The microphone is used for the voice control system and hands free telephony.

TOUCH SCREEN (TS)

The TS is located in the center of the instrument panel.

The controlling software for the voice system is contained in the TS. The software is responsible for starting and ending the voice engine in the AHU as well initiating any requested actions. It also provides information to a 'Say What You See' visual prompter in the TS which determines what is displayed during a dialogue with the voice system.

The driver can control voice functions by briefly pressing the voice button on the left steering wheel switchpack. The TS will then initiate a voice session in the AHU, allowing the user to say voice commands to activate some of the infotainment system features.

MICROPHONE

The directional type microphone is fitted to the driver side of the overhead console so that it is directed towards the driver.

It is connected to the AHU for hands free telephony and voice control systems. The AHU has an integrated noise suppression and echo cancellation system for hands-free telephone use.

INCONTROL TOUCH PLUS AUDIO SYSTEM - JAPAN

The Japanese voice system is part of the Japanese navigation system and uses the standard system components, with the exception that the map and voice data is not stored on the IAM hard disc drive. Additional components are:

  • A Navigation Control Module (NCM)
  • A Navigation Interface Module (NIM).

The two additional modules are used to read the map and voice data and output audio and video signals to the TS, IAM and Audio Amplifier module (AAM).

Navigation Control Module (NCM)

Navigation Control Module (NCM)

The NCM is located below the front right seat, attached to a bracket on the floorpan.
