Part 2
Audio System
Touch Screen Display (TSD)
The TSD is an 8" color touch sensitive display, located in the instrument panel, above the ICP.
Two versions of the TSD are available; single view and dual view. Additionally the switches surrounding the TSD differ depending on system specification, for example if navigation, dual view or parking aid is specified on the vehicle, these switches will replace tone, mode and set-up respectively.
The TSD is the Bus Master for the MOST system and contains the timing master for the MOST system.
When the vehicle systems become active the TSD is woken up by CAN (controller area network) bus activity and subsequently wakes up the other audio module via the MOST.
The TSD forms the basis of the audio system. It communicates with the rest of the audio/infotainment system on the MOST ring and allows control of the audio system and other infotainment systems from a single point. The TSD communicates with the IAM on the MOST ring and provides the primary user interface and display of the audio system controls. No configuration procedure is required if the TSD is replaced.
Calibration of the TSD using approved Land Rover diagnostic equipment enables updates to be downloaded as new technology becomes available or any fault concerns require software updates.
The TSD provides user control of the following systems:
Dual View
The dual-view TSD enables the passenger and driver to view completely different images from their respective seating positions. This technology has provided a solution for the legal issues attached to viewing moving images whilst the vehicle is in motion. It is not possible for the driver to view moving images with an active speed signal but the passenger can.
NOTE:
Due to legislation the NAS markets will not receive this option. A single view display is available in these markets.
The dual-view TSD uses Parallax Barrier Shutter Technology to alternately hide and reveal columns of pixels to the left and right hand views of the screen. The display comes with a specially designed agar coating to help prevent sunlight bleaching.
To access a TV or video image when the vehicle is in motion and single view is selected, the dual view button on the TSD should be pressed by either the driver or the passenger. This will then switch the TSD to dual-view mode allowing the passenger to view TV or video, but not the driver. A second press of the button will change the TSD back to single view.
Before and After Dual View Selection
Once dual-view has been selected, the driver can change the current screen without affecting the passengers view by the source on the TSD.
The audio system can only broadcast one audio source. Therefore, the TV / video source that is current for the passenger will also be the audio the driver can hear. If headphones have been specified as an option, then the passenger's can choose to listen to the sound source accompanying the TV / video. This allows the driver to listen to a different audio source or navigation commands via the vehicle speaker system.
The driver's view is also event driven, for example, if reverse gear were to be selected the rear view camera will be displayed automatically, overriding the currently displayed information.
Clock
The TSD contains the master clock functionality. Other vehicle infotainment modules that require clock functionality use the time supplied from the TSD.
The clock is available to any control module that is connected to an interconnecting bus, for example, either of the CAN (controller area network) buses or the MOST ring.
The clock display configurable to show in AM / PM or 24 hour format. Midnight is shown as 12:00AM or 00:00 respectively. The default condition, if not specified, after power on or delivery, should default to 12:00PM or 00:00. Depending upon the market set the clock will default to either 12 or 24 hour format.
The time is adjusted from the TSD. Under conditions when any bus system could be asleep or shut down, the TSD does not allow clock adjustments.
Integrated Control Panel (ICP)
The ICP is located in the instrument panel, above the ATC (automatic temperature control) module.
The ICP has a rotary control for audio volume control. The control can also be pressed to turn the audio system on and off.
The ICP duplicates many of the TSD audio user control features. Any volume setting made whilst in audio, TV, phone, navigation or voice activation mode will be memorized for that system. The ICP communicates with the TSD on the medium speed CAN (controller area network) bus. The TSD converts control/command signals from the ICP and then distributes the information onto the MOST system to the audio system and other information and entertainment systems.
A slot in the front of the ICP allows a CD to be inserted into the IAM.
Three buttons below the CD slot operate the following audio functions:
Seek Up
- Short press - Select next radio station up the frequency band
- Short press - Select next track on chosen audio source
- Long Press - Enter radio manual seek up the frequency band
- Long Press - Scan forward through a CD track
NOTE:
In radio manual seek, further short presses will change the frequency in single increments.
Seek Down
- Short press - Select next radio station down the frequency band
- Short press - Select previous track on chosen audio source
- Long Press - Enter radio manual seek down the frequency band
- Long Press - Scan backward through a CD track
CD Eject
- Press to eject CD from audio head unit.
Portable Audio Interface Panel and AVIO Panel
Both the front and the rear auxiliary input connectors are located in the floor console. AUX (Auxiliary Input) mode allows extra equipment to be connected to the vehicle's audio system. Items such as a personal stereo, MP3 player, hand-held navigation unit etc., can be plugged in to the vehicle's audio system.
To listen to an auxiliary input source portable devices must be connected via 3.5 mm stereo jack sockets or USB (universal serial bus) ports. If the device has a line out socket it is preferable that this is used for connection.
Portable Audio Interface
The portable audio interface is located in the floor console cubby box and is fitted to all Hi-Line and Premium audio specified vehicles. The interface is a media hub between the portable input device and the IAM. The interface contains two USB (universal serial bus) ports and a 3.5mm jack plug connector.
Devices that can be connected to the portable audio interface include:
- USB (universal serial bus) mass storage devices (for example a memory stick). Devices must use FAT or FAT32 file format.
- iPod(R) (iPod Classic, iTouch, iPhone and iPod Nano are supported - full functionality for older devices cannot be guaranteed). iPod Shuffle functionality cannot be guaranteed.
- Auxiliary device (personal audio, MP3 players).
- Devices with Bluetooth(R) connectivity. Devices must support A2DP and AVRCP Bluetooth(R) protocols).
When connecting a portable storage device, select AUX on the TSD to select that device input. Depending on the device connected, many of the audio controls on the TSD and ICP can be used.
NOTE:
It is recommended to disconnect an iPod when leaving the vehicle. Failure to do so may result in the iPod battery discharging.
To maximize playback quality, it is recommended to use lossless compression for any media files on iPod. Failing this, it is recommended that compressed files utilize a minimum bit rate of 192 kb/s (a higher bitrate is strongly recommended for increased quality playback).
For media files delivered via USB (universal serial bus) or MP3 players, the highest compression rate supported is 320 kbits per second (kbps). If anything less than 128 kbps is used, Digital Signal Processing (DSP) functionality may be lost.
Some MP3 players may have a file system that is not supported by the IAM. To use an MP3 player, it must be set to USB (universal serial bus) Removable Device or Mass Storage Device mode. Only music that has been added to the device in this mode can be played.
AVIO Panel
The Audio Video Input/Output (AVIO) panel is located at the rear of the floor console. The AVIO panel is only fitted to vehicles with RSE installed.
The panel contains one USB (universal serial bus) port and three Audio/Video (AV) plug sockets. The AVIO panel is connected directly to the Rear Seat Entertainment (RSE) module.
The AV sockets allow for the connection of video (yellow socket), right audio (red socket) and left audio (white socket) from a remote device such as a PlayStation. The USB (universal serial bus) socket allows for the connection of a portable media device.
Steering Wheel Controls
The steering wheel mounted audio control switches are located on the LH (left-hand) side of the steering wheel. The switches are a resistive ladder type which return a different voltage to the ICP in response to different switches being pressed.
The steering wheel audio switch controls the following functions:
- MODE - Press repeatedly to scroll through all audio/video sources.
- Short press up -
- to select the next radio preset
- to select the next track on chosen audio source
- when telephone is in use, press to scroll up lists of calls or phonebook entries.
- Short press down -
- to select the previous radio preset
- to select the previous track or start of current track on chosen audio source
- when telephone is in use, press to scroll down lists of calls or phonebook entries.
- With radio manual seek mode activated, further short presses will change the frequency in single increments. A further long press will scan forwards through the current waveband until the button is released
- Long press up -
- to auto seek up the frequency to the next radio station.
- Long press down -
- to auto seek down the frequency to the next radio station.
-
- Volume increase for any audio source
- Volume decrease for any audio source.
Digital Audio Broadcasting (DAB)
DAB Receiver
DAB is a digital radio network designed to provide reliable, multi-service broadcasting for reception by mobile, portable and fixed receivers.
DAB provides a clear signal with minimal interference, hiss or fading. After a channel (or station) has been tuned and stored, it does not need retuning.
NOTE:
Radio signals travel in a straight line so large obstacles, such as tall buildings, can shield the vehicle from the signal causing temporary loss of reception (known as dead spots).
Digital radio is transmitted from regional terrestrial transmitters. Local digital radio channels are not available outside the range of a transmitter. To receive new local channels during vehicle movement around a country, the auto-tune function is used to build new channel lists.
NOTE:
When the vehicle DAB radio is first used the system will not receive any digital stations until the auto-tune function has been completed.
Digital radio channels are organized into groups called ensembles (also known as multiplexes). Some individual channels may also provide a number of subchannels. For example, if several sports events are being held simultaneously, the channel may temporarily choose to broadcast each different event on a separate subchannel.
DAB is broadcast across Europe, Canada and parts of Asia. System transmission is via a terrestrial network, on two separate broadcasting bands:
- DAB band-L - Received from roof pod or Sigma pod antenna
- DAB band III - Received from spoiler mounted antenna.
The DAB system requires additional components to be added to the audio system. DAB antennas and a receiver are fitted to allow reception of the service.
Operation of the DAB system is the same as the radio operation with selections made through the TSD and ICP to access and navigate the system functions.
The DAB receiver is a dedicated tuner which is controlled by the IAM on the MOST ring. The receiver processes the signals from the DAB antennas. Information is transmitted on the MOST ring and processed by the IAM. The processed information is sent out to the power amplifier and broadcast through the speaker system.
No configuration procedure is required if the DAB receiver is replaced. Calibration of the DAB receiver using Land Rover approved diagnostic equipment enables updates to be downloaded as new technology becomes available or any fault concerns require software updates.
Satellite Digital Audio Radio Service (SDARS)
SDARS Receiver
The Satellite Digital Audio Radio Service (SDARS) receiver is located in the RH (right-hand) side of the luggage compartment. The receiver is a dedicated tuner which is controlled by the IAM on the MOST ring. The receiver filters the signals from the satellite radio antenna located in the roof pod or sigma pod. Information is transmitted on the MOST ring and processed by the IAM. The processed information is sent out to the power amplifier and broadcast through the speaker system.
The digital radio format adopted for NAS vehicles is satellite radio operating in the S-Band frequency range (2.3 GHz). SDARS service provider 'Sirius' transmit a signal from their up-link facility (which is the original point of transmission of data, voice or other information through an antenna system) to a satellite where the signal is then down linked to both the terrestrial repeater network and the individual satellite car radios. The radio switches between the satellite signal and the repeater network signal depending on the strength of the signal at any given time.
The Sirius satellite system comprises:
- Satellites
- Ground repeaters
- Up-link ground stations
- Radio receiver systems
The Sirius satellite radio system uses three satellites on an inclined elliptical orbit. This ensures that each satellite spends approximately 16 hours a day over the continent of North America, with at least one satellite over the country at any one time.
The satellites beam their signals down to the ground where the signal is picked up by receivers or is transmitted to repeater stations to cover built up areas where the signal is obscured. The satellite service comprises over 100 channels of digital entertainment which is provided by subscription requiring a monthly payment. In order to obtain a subscription the SDARS unit ID number will need to be retrieved from the unit. This is achieved as follows:
- When the vehicle first receives live signal within the US or Canada, the TSD will display ch184 as the tuned channel (labelled as Preview). The radio text will display Call 1888-539-Sirius. Alternatively, when the radio is subscribed, unsubscribe channels shall also display this information in the radio text
- The ESN/SID can always be found the following way, regardless of the subscription status of the radio. Press Settings on the TSD, then select Sat Info icon in the settings view. This will display the ESN/SID and the phone number. If a cell phone is paired to the Bluetooth system, the user can select the green phone button in the Sat info view to call the call center.
If no subscription has been taken, the TSD will display the Sirius telephone number. To subscribe to Sirius use the displayed phone this number. The user will need payment details, the Sirius ID number and details of the required package.
The SDARS function is accessed by pressing the SAT button. This allows the user access to another bank of possible favorites, with the option to store 6 favorites on each of SAT 1, SAT 2 and SAT 3.
Operation of the satellite radio system is the same as the radio operations with selections made through the TSD and ICP to access and navigate the system functions.
No configuration procedure is required if the SDARS receiver is replaced. Calibration of the satellite radio receiver using approved Jaguar diagnostic equipment enables updates to be downloaded as new technology becomes available or any fault concerns require software updates.
HD Radio
HD Radio technology is a free digital radio format broadcast available in the NAS market and may become available for other markets in the future. HD Radio digital broadcasts are transmitted alongside the analogue AM and FM signals by stations broadcasting HD Radio signals. HD Radio technology has the ability to deliver improved sound quality and content to the listener, blending between analogue and a digital audio streams of the primary station and delivering extra multicast stations on the same frequency. The HD Radio receiver is integrated into the AM FM tuner on NAS variants of the IAM.
Amplifier
The audio system has two amplification options dependent on the audio system specified:
- 380W Amplifier - Hi-Line systems
- 825W Surround Sound Amplifier - Premium systems.
The amplifier is located under the LH (left-hand) front seat. It is connected to the audio system via the MOST. Speaker connections are hardwired.
TV Tuner
The TV tuner is located below the LH (left-hand) front seat. The TV tuner forms part of the entertainment system and is available on vehicles fitted with satellite navigation. The TV images can also be viewed on the RSE rear screens when fitted.
TV audio output is sent from the TV tuner on the MOST to the audio power amplifier.

REAR SEAT ENTERTAINMENT (RSE)
RSE Module
The RSE system consists of the following components:
- Passenger infrared touch screen remote control panel (mounted in the rear of the floor console)
- Two 8'' LCD video display screens (mounted in the back of the front headrests)
- DVD video player (IAM)
- Rear AVIO panel connectivity
- RSE module
- Two headphone sets (three for dual view vehicles).
The fibre optic, Media Orientated System Transport (MOST) based system provides video and audio entertainment for the rear seat occupants. The RSE system provides control of a number of audio and video sources, channelling the output independently to the rear seat passengers via personal infrared digital wireless headphones and video screens or allows output over the main vehicle audio speaker system. The video images can also be displayed on the front Touch Screen Display if the vehicle is below a predetermined speed threshold (or dual view is selected by the passenger).
The video display screens mounted in rear of the front seat headrests can display video pictures from a number of sources and are controlled via the RSE remote control for the rear seat entertainment controls.
The RSE module is located in the RH (right-hand) side of the luggage compartment and manages the request signals from the RSE remote control. The module is connected directly to both rear video displays via a medium speed CAN (controller area network) link. Infrared signals from the RSE remote control are received by the rear video display screens and user requests are communicated via the medium speed CAN (controller area network) link to the RSE module. Video signals are communicated via the LVDS (Low Voltage Differential Signal) to one or both screens as requested.
The RSE module is connected directly to the following modules for the purpose of processing audio, video, input and output signals:
- TSD - DVD video and TV to rear screens
- Audio power amplifier - Process audio signals for output on vehicle speaker system or headphones
- TV Module - TV signals processed and passed to TSD and rear screens
- Rear screens/RSE remote control - process infra-red signals
- AVIO panel - process audio and video signals from remote source.

ANTENNAS - ALL AUDIO SYSTEMS
The AM/FM, DAB band III, VICS and two of the four TV antennas, are located in the rear spoiler. They are part of the spoiler assembly which is a bonded component and therefore are not serviceable as separate items.
Two additional TV antennas are located in the rear quarter window glass and their amplifiers are located above the window glass. For additional information, refer to Video System Component Locations
The rear spoilers for 3 and 5 door models are physically different components. Each variant spoiler has five options of antenna configuration dependant on infotainment equipment level and vehicle market.
SDARS and DAB Band L antennas are located in the roof pod or sigma pod (depending on vehicle roof specification). The roof pod and sigma pod are also used for GPS reception for the satellite navigation system, when fitted.
